Холодная сварка для металла инструкция по применению

Холодная сварка для металла в течение последнего времени набирает все большую популярность, следовательно, в продаже появляются все новые и новые её разновидности. Так что же такое холодная сварка и как ее применять, Вы найдете в нашей инструкции.

Некоторые считают, что холодную сварку используют, чтобы соединять металлические детали всевозможными композитными материалами. Но думать так про холодную сварку – это не правильно. Понятие холодной сварки подразумевает самую настоящую жидкую сварку, выполняемую без нагревания свариваемых деталей.

Принцип действия данного процесса заключается в том, что при сваривании металлических деталей на них оказывается влияние одновременного направленного деформирования.

Используя холодную сварку, можно выполнять соединения достаточно разнородных материалов. Например, можно сварить посильно серебряную деталь и алюминиевую. Это означает, что составные части сварного соединения могут иметь совершенно разный химический состав и другие физические свойства. Когда осуществляется холодная сварка, такие параметры как температура и давление, не играют существенной роли.

как пользоваться холодной сваркой для металла

Добрый день. Что такое холодная сварка? Об этом пойдет речь в сегодняшнем посте. Это мой первый пост в 2018 году после новогодних праздников с которыми  вас друзья и поздравляю ! Рассмотрим инструкцию как использовать холодную сварку.

 

Холодная сварка. Как пользоваться холодной сваркой?

Это разновидность клея, ну или можно его так назвать,  который при застывании превращается в твердую субстанцию. Результат применения этого вида сварки, можно получить соединение выполненное профессиональным сварочным аппаратом.

Если сказать честно, такой вид восстановления подходит далеко не всем ремонтникам и домашним мастерам очумелых ручек. К примеру для восстановления  деталей испытывающими серьезные нагрузки такой вид сварки применять не рекомендую, хотя производители обещают высокую прочность таких соединений.

Для начала посмотрите вот это видео:

Собственно говоря путем таких манипуляций можно скреплять металл, пластмассу, полимеры, бетон да собственно любые материалы. Будьте уверены, что результат вас порадует — это проверено на личном опыте.

Вот еще одно видео по теме

В этом ролике такой вид сварки называют шпатлевка, ну в принципе и я соглашусь с автором немного по своему внешнему виду похожа.

Как выглядит холодная сварка.

А чуть не забыл сама по себе холодная сварка это эпоксидный клей, а такое название она получила из-за своих специфических свойств при скреплении поверхностей.

Имеются два основных вида холодной сварки:

Брусковая .

Она представляет из себя «колбаску» которая состоит из двух слоев. Верхний слой более тонкий по сравнению с  центральной сердцевиной бруска. Для использования достаточно отрезать кусочек этого состава и как в детстве при лепке пластилином помять ее в руках. Перемешав и хорошенько разогрев холодную сварку можно лепить на соединяемые поверхности и скреплять их.

Жидкая (двухкомпонентная).

Тут немного сложнее. Мы имеем два тюбика как зубная паста, но зубы лучше ей не чистить. Мы выдавливаем из одного и другого тюбика компоненты и смешиваем их в пропорции 1:1. Перемешивать необходимо до получения однородной массы. Когда мы этого добьемся, то все чудо клей готов. Можете использовать. Такой вид этого клея наиболее предпочтителен, так как после вскрытия и смешивания холодная сварка не хранится. А в данном случае можно просто закрыть тюбики и воспользоваться клеем через любой временной промежуток.

Советую почитать про гаджет Ploota. Особенно будет полезно тем кто не умеет плавать.

Как пользоваться холодной сваркой и меры предосторожности.

Едем дальше обсудим вопрос — как использовать холодную сварку. Для прочного и долговечного соединения необходимо соблюдать ряд правил, а каких сейчас мы рассмотрим.

1.  Перед нанесением холодной сварки необходимо хорошо очистить соединяемые поверхности и по возможности обезжирить.
2. После того как вы смешали или размяли в руках клей у вас есть 5 минут до его затвердевания. Действуйте быстро.
3. Если вы хотите ускорить процесс склеивания (сваривания) поверхностей можно немного подогреть соединение, но сильно разогревать не стоит.
4. Когда холодная сварка затвердела окончательно вы можете ее обработать напильником или наждачной шкуркой для придания более эстетичного вида.

Не допускайте попадания холодной сварки в глаза и открытые раны. Если же это произошло срочно промойте рану водопроводной водой и при необходимости обратитесь к врачу

Примеры склеивания поверхностей холодной сваркой. Что можно заклеить.

С помощью холодной сварки можно закрепить и отремонтировать много различных элементов, таких как:

• Металлически детали, трубы, кронштейны и др.
• Различные пластиковые изделия. Но помните, что холодная сварка разъедает изделия из полиэтилена.
• Изделия из камня натурального и искусственного.
• Стеклянные предметы.
• Смешанные материалы. Например можно приклеить стекло к камню или пластику.
• Керамика различных видов.
• Линолеум.

В принципе лично мое мнение, что это более клей чем сварка и такое название это просто какой то пиар ход который производители умело раскручивают на просторах нашей необъятной родины.

На этом фото вы видите как с помощью этого чудо клея заделывают пробоины в водопроводной трубе. Перед тем как это сделать высушите хорошенько все поверхности. В противном случае такое соединение будет не прочным.

Тут мы видим как соединили стержень и полусферическую поверхность. Такое возможно только если в последующем эта конструкция не будет испытывать серьезных нагрузок на изгиб и излом. Хотя такое применение холодной сварки встречается достаточно редко.

Присоединить часть кронштейна который был отломан в результате удара не составила ни какого труда. Ну тут мы скорее видим не отломанную часть, а трещину которая была загерметизирована клеем. И даже не сомневайтесь такая герметизация выдержит достаточно высокое давление.

Пожалуй на сегодня все. Думою сегодняшний пост получился достаточно информативным и теперь у вас не возникнет вопроса — как использовать холодную сварку. А если у вас еще остались какие нибудь вопросы по данной теме пишите мне в комментариях или на почту обсудим.

90000 Cold Welding: Joining Metals Without Heat 90001 90002 When we think of a welding procedure, the very first thing that springs to our mind is the use of heat. Heating the metals to their melting point and fusing them together is how most welding techniques work. 90003 90002 90005 RELATED: FRICTION STIR WELDING: PRINCIPLE, BENEFITS, AND APPLICATIONS 90006 90003 90002 Techniques like arc welding, friction welding, ultrasonic welding, and laser welding, all involve heat in some way or another.In fact, heat is considered synonymous with welding and is integral to join two materials. 90003 90002 But this is far from the truth and cold welding is the obvious proof. Cold welding is the process of joining two metals without using heat. 90003 90002 It might sound impossible, but it is one of the most popular welding methods out there. 90003 90002 The element of heat in a welding process is used to make the parts plastic enough so that diffusing of the atoms can take place, either between the two workpieces or with a different medium in the middle.90003 90002 However, it is not mandatory to use heat to join materials. Cold state welding demonstrates that in real-time. 90003 90002 Cold welding (also known as cold pressure welding and contact welding) uses pressure to join two materials. Scientifically, this process is called solid-state diffusion and it uses pressure to create welds. 90003 90002 When two materials are pressed together, they generally do not weld to each other. This is mainly due to the fact that there is an oxide layer or a thin barrier on the surface of the materials.90003 90002 If we take the case of a metal, an oxide layer on the surface is like a barrier that does not allow it to diffuse with another metal. 90003 90002 Cold welding overcomes this issue by preparing the metals before they are welded. The preparation process involves cleaning or brushing the metals to such an extent that the top oxide or barrier layer is removed. 90003 90002 This is achieved by de-greasing the metal and then wire brushing it. 90003 90002 Once the desirable surface cleanliness is obtained, both materials are pressed together mechanically with the right amount of force.The amount of force depends on the material itself, as some materials may only weld at high pressures. 90003 90002 One of the conditions required for cold welding is that at least one of the materials must be ductile and must not have undergone severe hardening. 90003 90002 This obviously narrows down the list of materials that can be the candidate for the cold welding. Soft metals are the best choices for cold welding. 90003 90002 90035 90036 90003 90002 The most common joints that are possible with cold welding are: 90003 90002 In Butt joint, removing the barrier layer of the metal is not often required as the plastic deformation that happens during the joining process breaks up the barrier automatically .However, lap joints do require special treatment because otherwise, the material will not adhere to each other. 90003 90002 Cold welding has centuries of history to it. Excavators have found cold weld utensils that date back to the bronze age. 90003 90002 The first scientifically made cold weld experiment was done in 1724 by Reverend J I Desaguliers. 90003 90002 His experiment was fueled by the observation that when he pressed and twisted two lead balls of the same diameter together, they would stick to each other.Further testing showed that sometimes, the bond strength is almost similar to the parent metal. 90003 90002 There have been many theories that tried to explain this phenomenon including recrystallization and energy hypothesis. However, they all have been disproved. 90003 90002 Currently, the accepted explanation is the creation of a metallic bond that comes as a result of the interaction between the free ions and electrons when two metals are pressed together. 90003 90002 When cold welding is done with the right procedure and material treatment, the results are often as strong as the parent metal.90003 90002 90055 90036 90003 90002 Perfect cold welding is very hard to achieve. This is due to several reasons like oxide layers that form on top of the metal in atmospheric conditions, surface irregularities, surface contamination, and more. 90003 90002 Optimum cold welds only happen when the two surfaces that are being pressed together are clean and free from any form of contaminants. Also, more flat and regular the surface is, the easier and uniform the weld is going to be. 90003 90002 Also, there are limitations on the types of metals that cold welding can join.Non-ferrous soft metals are the only candidates suitable for cold welding. 90003 90002 Copper and Aluminum are the two most commonly cold-welded metals. Metals that contain carbon are not possible to cold weld. 90003 90002 90067 90036 90003 90002 The most noteworthy advantage of cold welding is that the resultant welds have the same bond strength that of the parent material. This feat is very hard to recreate in metalworking. 90003 90002 Cold working can also weld Aluminum 2xxx and 7xxx series which is often not possible with other forms of welding.90003 90002 In industries, cold welding is known for its ability to weld aluminum and copper together which are often hard to weld with other forms of weld techniques. However, the bond created between the two materials by cold welding is very strong. 90003 90002 Cold welding provides clean and strong welds without the formation of brittle intermetallic compounds. 90003 90002 Cold welding is mostly applied in welding wires. Since there is no heat involved and the process can be done quickly, cold welding can ensure perfectly welded wires, mainly with aluminum, copper, 70/30 brass, zinc, silver and silver alloys, nickel, and gold.90003 90002 There are even handheld tools available that you can use to cold weld wires, making it very portable and easy to use. 90003 90002 90083 90036 90003 90002 Cold welding is also used in cases where dissimilar metals have to be joined, like the one between the copper and aluminum that we already discussed. 90003 90002 90005 RELATED: LASER WELDING: TYPES, ADVANTAGES, AND APPLICATIONS 90006 90003 90002 Cold welding provides one of the most solid welds for creating parent metal like bonds.It does not require heat energy nor special tools. Among the most popular weld techniques, cold weld shows that heat is not necessary if you are joining specific types of materials. 90003.90000 Pressure Welding Machines Limited – What is cold pressure welding? 90001 90002 90003 90004 90005 90002 90003 90004 90005 90002 Cold pressure welding is a form of solid phase welding, which is unique because it is carried out at ambient temperatures. (Other forms of solid phase welding are conducted at elevated temperatures, but although these temperatures are high, the material is not molten, merely more ductile.) 90005 90002 As early as 3,000 BC, the Egyptians prepared iron by hammering a metal sponge in order to weld the red-hot particles together.Blacksmiths have also hammer welded wrought iron for centuries. This type of welding was always carried out at high temperatures. 90005 90002 The first known example in Britain of hammer welding at ambient temperatures (therefore true cold pressure welding) dates back to the late Bronze Age, around 700 BC. The material used was gold, and gold boxes made by this process have been found during excavations. 90005 90016 Discovery of cold pressure welding 90017 90002 90019 The first scientific observation of cold pressure welding was made in тисячу сімсот двадцять чотири by the Reverend J I Desaguliers.He demonstrated the phenomenon to the Royal Society and later published the details in the scientific journals of the time. Reverend Desaguliers discovered that if he took two lead balls about 25mm each in diameter, pressed them together and twisted them, then the two pieces would join together. The joint strength was measured on a steelyard and although the results were erratic, good bonds were produced, with some as strong as the parent material. 90005 90002 After Reverend Desaguliers ‘discovery in the 18th century, it appears that very little happened until the Second World War.This accelerated developments, especially in Germany, where light alloy cooler elements for aircraft were pressure welded, although it is understood that this welding was carried out at elevated temperatures. 90005 90002 Seen for the first time, cold pressure welding can appear an almost magical process. People unfamiliar with it are often reluctant to accept a method of welding that does not involve heat or electricity and some form of flux to make the joins. After a demonstration, they inevitably ask, “How are the two pieces of metal joined?” 90005 90002 There have been several explanations as to the actual mechanism by which a cold pressure weld is obtained.For example, it has been suggested that it happens via recrystallisation or by an energy hypothesis, but most explanations have been either experimentally disproved or refuted on theoretical grounds. 90005 90002 The currently accepted hypothesis that accounts for a cold pressure weld taking place involves the atoms of metals being held together by the metallic ‘bond’, so called because it is peculiar to metallic substances. The bond can be described as a ‘cloud’ of free, negatively charged atoms formed into a unit as a result of attractive forces.90005 90016 Creating a weld 90017 90002 90032 Therefore, if two metallic surfaces are brought together with only a few angstroms separation (there being 300 million angstroms to one centimetre) interaction between the free electrons and ionised atoms can occur. This will eliminate the potential barrier, allowing the electron cloud to become common. This, in turn, results in a bond and therefore a weld. 90005 90002 A simpler way of explaining this rather awesome process is that if two surfaces are put together, both being anatomically clean and anatomically flat when considered on an atomic scale, a bond is effected equal to that of the parent material.90005 90016 Early applications 90017 90002 In practice, however, bonding is virtually impossible under most conditions, because of surface irregularities, organic surface contamination and chemical films such as oxide films. 90005 90002 In order to obtain maximum weld efficiency, any form of contamination must be reduced to a minimum, while the area of ​​contact, the weld area, has to be made as large as possible. 90005 90002 In earlier applications of cold pressure butt welding, the upset and radial displacement of the interfaces was undertaken in a single step.This technique had several disadvantages: it was necessary to square off the ends to be joined; both surfaces had to be kept free of contamination; and the amount of material which projected from the gripping die was such that bending and lack of coaxiality could occur, thereby spoiling the correct flow of metal. 90005 90016 The multi upset principle 90017 90002 90047 Then came the system of butt welding developed by GEC, employing what is known as the ‘multi upset principle’. When the material is inserted in the die, each time the machine is activated, the material is gripped by the die and fed forward.90005 90002 In this way, the two opposing faces are stretched and enlarged over their entire surface area as they are pushed against each other. The oxide and other surface impurities are forced outward from the core of the material and a bond is effected. A minimum of four upsets is recommended to ensure all impurities are squeezed out of the interfaces. 90005 90002 The advantages of this type of welding are easily seen in practice. The ends of the wire or rod need no preparation prior to welding and the alignment of the two butt ends is automatic as the material is placed in the die.There is no heat setting to be arrived at; no gap setting to be made, as this is built into the die; and no spring pressure to be set. Any one of these things incorrectly set on a resistance butt welder would result in a weld failure. 90005 90016 Suitable metals 90017 90002 90056 Cold pressure welding is restricted to nonferrous materials or, at best, soft iron that has no carbon content. Most nonferrous metals can be cold welded, and while copper and aluminium are the most common, various alloys such as Aldrey, Triple E, Constantan, 70/30 brass, zinc, silver and silver alloys, nickel, gold and many others have good cold weldability.Plated wires, including tinned copper, silver plated and nickel-plated, can all be welded to themselves or to plain copper. 90005 90002 The usual methods of joining dissimilar metals such as copper and aluminium, namely resistance welding, friction welding or flame brazing, will all result in a rapid breakdown of the joint. This reaction in a copper / aluminium joint begins to take place as soon as the two metals are placed together. 90005 90002 The problem is created by the oxides and the air space, which are left between the interfaces during these methods of welding, rather than by the dissimilarity between the metals themselves.However, with cold pressure welding, these oxides and air spaces are squeezed out in the weld process and, since no heat is applied, only the metallurgical changes that operate at ambient temperatures occur. 90005 90002 Cold pressure welding provides the most satisfactory way of joining copper to aluminium without the formation of brittle inter-metallic compounds. The quality is excellent because it produces a worked structure as opposed to the cast structure obtained in fusion welding. Also, there is no heat-affected zone with unsuitable properties.90005 90002 To test weld strength, most people rely on a tensile tester. Alternatively, you can make a reverse bend test. However, the most stringent test is to pass the weld though a number of dies in a wire drawing machine. 90005 90016 The role of dies 90017 90002 90069 The dies play an important role in the cold butt weld process. Firstly, they must grip the material firmly and, therefore, the inside of the cavity is either etched with an electric pencil or, when the die is to be used for welding large pieces of aluminium, grip marks are put in the cavity before the die is heat treated.90005 90002 The gap between the two faces, or noses, of the die is also extremely important. If it is too large, the material will just collapse or bend away. This dimension is taken care of during manufacture and can not be changed. 90005 90002 Finally, there is the offset of the die noses, which has the effect of making the weld look out of line around the circumference of the material. The purpose of the offset is to break the flash into two halves, so that removal is easy: otherwise the flash is likely to remain as a loose ring around the material and have to be cut off.The noses of the die also have to be sharp enough to virtually pinch off the flash around the weld, again to ensure that the complete flash can be easily removed. 90005 90002 The hardness and the temper of the die are most important as well. In the early days of cold welding, die breakage was very common and long after a machine was designed to weld 8mm copper rod, there were problems in containing the necessary forces within a die of this size. 90005 90002 PWM has been producing dies to extremely high standards and tolerances for over 30 years.As wire technology has improved, so has the demand for precision. PWM’s on-going research and development programme has enabled it to produce dies that are capable of joining extremely fine wire. PWM was the first company outside the USA to develop a die that could be used in conventional cold welders to join wire as fine as 0.08mm (0.003145 “) in diameter. Individually handmade in matched sets to the highest possible tolerances by skilled craftsmen, PWM’s industry standard dies can now be produced for wire sizes between 0.08 (0.003145 “) and 6.50mm (0.256”). Dies can also be manufactured to suit round or profile wires and rods according to customers ‘specifications. 90005 90002 PWM dies can also be manufactured to suit various profiles, as long as the profile allows the die to be made in two halves – which is necessary for the removal of the welded wire – and the cross-sectional area is within the capacity of the machine. 90005 90002 It is also possible to weld two different wire sizes together. Generally, the larger diameter should not be more than 30% greater than the smaller.If the copper is considerably smaller in diameter than the aluminium, the copper will merely embed itself into the aluminium and no weld will be achieved. 90005 90002 90005.90000 Common Mistakes to Avoid In Pipe Welding 90001 90002 Pipe welding or pipe fabrication is a method where two pipes are joined together. This process is achievable through different welding methods like Arc Welding, MIG Welding, TIG welding, and several other welding techniques. 90003 90002 Job opportunities for welders have risen over the years thanks to the booming industries. 90003 90002 90007 RELATED: SEAM WELDING: APPLICATIONS, ADVANTAGES, AND DISADVANTAGES 90008 90003 90002 However, Pipe welding in industries requires skilled workers.Since welding is a complex process, the margin for errors to occur is quite significant. 90003 90002 Hence, precision and resistance are key in this field. 90003 90002 Mistakes in pipe welding can happen from both beginners as well as experts. Understanding them is the best way to prevent such occurrences from happening in the first place. 90003 90002 Mistakes in welding pave the way for weld defects. Recently, Honda had to recall some of their CR-V models because of a faulty weld that could result in fuel leakage.The Kursk Submarine Disaster is another example of how weld defects can cause massive harm to not just machines, but also human lives. 90003 90002 Pipe welding processes need to be on point because any mistake could result in a leak of the payload. Let’s look at some of the common mistakes in pipe welding that are common in the industry. 90003 90002 Preparation of the pipe is very important when it comes to pipe welding. There are only a hand few of welding processes that do not require workpiece prep before welding.90003 90002 This preparation of the pipes begins with ensuring that the edges to be joined are smooth and uniform. 90003 90002 In many cases, the pipes to be joined would have undergone some sort of cutting or welding before it reaches the hands of the welder. So before the actual weld process, a surface grinding procedure is often used to get the edges right. 90003 90002 The next step is cleaning the pipes to remove any form of lubricants, oils or other contaminants present on the pipe surface.90003 90002 Without following good pipe preparation practices, the weld is likely to face multiple challenges such as hydrogen inclusion, slag entrapments, and lack of fusion. These ultimately result in weaker welds and weld defects. 90003 90002 Even though the filler material will adjust to resolve minor alignments of the surfaces, there is a limit to what it can achieve. When parts are not joined at the right alignment, we see instances like a bevel with too steep of an angle. 90003 90002 Part fit-up is standard procedure in pipe welding.However, sometimes we see welders rushing the process and this creates misalignment welding defects that are both unsightly as well as structurally weaker when compared with a proper weld. 90003 90002 90003 90002 90037 90038 90003 90002 WPS or Welding Procedure Specification is a document that contains information targeted towards the welders, helping them with making welds that are in line with the code requirements. Too often, experienced welders ignore going through such documentation.90003 90002 But that is not a wise choice. Pipe welding has many variables from the material of the pipe to the type of weld that is being used in the process. 90003 90002 A WPS will have all sort of information that is relevant to the welding process like weld type, welding positions, filler material classification, preheat temperatures, post-heat temperatures, weld treatment, and much more. 90003 90002 Referring to the WPS before starting the welding process is always a good practice. 90003 90002 Preparation of joints does not have a universal procedure that you can follow.These procedures change according to the type of welding used. 90003 90002 Preparing a joint for stick welding is not as same as that used in MIG welding. They both require a different set of approaches and using the right one for the right weld is the only way you can ensure perfect pipe welds. 90003 90002 Without following the right weld procedure, you will end up with serious weld defects. 90003 90002 Shielding gas is used to present the weld from interacting with atmospheric gases like Hydrogen and Nitrogen.Many weld processes like laser welding use shielding gases to create better welds. 90003 90002 However, one among the most common misconception that many welders have is that more shielding gas will offer more protection. However, this is not true, and in some cases, it can even adversely affect the weld. 90003 90002 High-pressure welding gas at full speed wastes a lot of shielding gas without any advantages. Also, the force from the shielding gas can agitate the weld puddle. 90003 90002 It is always recommended to use a flow regulator to ensure that the weld receives the proper amount of shielding gas.90003 90002 Many welders blame the power sources for the porosity in the welds. A power source can not cause the weld to become porous. 90003 90002 However, other factors like changing the wire spool, using the wrong gas, or not prepping the workpieces often lead to porosity in the welds. 90003 90002 This goes to show that the welder must remain cautious at every step of the process to ensure good pipe joints. Things that appear seemingly harmless, such as the momentary disruption in a gas flow can create porosity in the welds.90003 90002 Arc welding often causes the formation of slag. Flux coating plays a major role in creating slag inclusions. 90003 90002 Welders must use the correct speed and angle to ensure that slag production is restricted to minimal levels. Slag inclusion can also be prevented by using the right amount of voltage for the welding wire. 90003 90002 Cleaning between weld passes is another way you can prevent slag accumulation. 90003 90002 90003 90002 90077 90038 90003 90002 Pipe welding requires a strong and perfect weld.Why this is important is easy to understand because bad weld jobs result in leaks that can cause serious damages based on the fluid that it will hold. 90003 90002 90007 RELATED: COLD WELDING: JOINING METALS WITHOUT HEAT 90008 90003 90002 Hence, mistakes are not an option. As a welder, you need to make sure that each step of the process is done to perfection. 90003 90002 When you follow every single step with caution and perfection, you leave no room for error. 90003.90000 Cold Tig Welder Metal Cold Welding Machine Welding Wire Tig Cold Welder Aluminum Stainless Tube Copper Welder No Deformation 90001 90002 90003 90004 Metal cold welding machine 90005 90006 90007 90002 90003 90004 Welding wire for cold welding 90005 90006 90003 90004 machine TIG welder 90005 90006 90007 90002 90003 1.Welding Machine Difference 90020 At present, there are three kinds of welding machines in the market: 90020 (1) Argon arc welding machine: the argon arc welding machine has high welding efficiency, but in the welding process, the 90020 deformation is large, the weld joint is rough, and so on.It is the welding machine with the highest utilization rate on the 90020 market at present. But it takes 3-5 years for argon arc welders to mature and cost a lot of labor. Limited to “people”. 90020 (2) Laser welding machine: its expensive price is enough to make people hesitate. 90020 (3) Precision cold welding machine: welding principle is high frequency discharge and instantaneous high temperature principle. 90020 Its welding characteristics are silver white, small deformation, and clean fish scale.Ordinary workers are also operable, 90020 focusing on the release of “manual”. Not limited by operation and its welding characteristics, it can save a lot of labor costs 90020 and solve the trouble caused by the follow-up process. 90020 2.Main Functions 90020 (1) Repair cracks as this machine with good compact and permeability. 90020 (2) Soldering thin stainless steel plate, table-board, tube together. 90020 3.Application Essentials 90020 (1) Main characteristics of thin plate cold welder welding: 90020 When CWT (Cold Welding Technology) is used to weld stainless steel sheet, the effect is obviously better than that of traditional 90020 welding machine.It has the advantages of small output current, less heat concentration, less heat affected zone, smaller welding 90020 deformation, uniform heat source input at all points of the weld, better control line energy, cooling effect of protecting gas 90020 flow, reducing surface pool temperature and increasing surface tension of the weld pool, simple operation, mechanical properties 90020 of the weld and so on. It has the advantages of good compactness and beautiful surface forming. 90020 At present, CWT welding is widely used in all walks of life, especially in stainless steel sheet welding.90020 (2) Splice welding: 90020 Splice welding refers to splicing two sheets of the same thickness into one piece, or welding the rolled sheet into a whole, when 90020 splicing welding, the splicing seam of spare parts should be small and flat. 90020 4.Advantages 90020 (1) Small heat affected zone while welding. 90020 (2) No need preheating processing, no need annealing for the work pieces after welding. 90020 (3) No deformation and edge after welding. 90020 (4) No air hole and sand holes after welding.90020 (5) Precise and accurate: can weld very small and precise part, the finest wires used for welding can be 0.10mm-0.20mm. 90020 (6) It is convenient and flexible for welding, site repair is also available. 90020 (7) Widely used in repair all cracks, sand holes, collapse edges, corners, abrasion, etc. 90020 (8) It is also available welding the toughing mouth of cold dies and tools. Thus exempt from the preheating, heat preservation 90020 process of ordinary arc welder. 90020 5.Applications and introduction 90020 (1) Kitchen Equipment / Stainless-steel Table Board / Sink.90020 (2) Stainless-steel Products / Stainless-steel Advertisement Characters / Advertisement Frames / Doors and Windows / Light Box / Main 90020 Case / Electricity Box. 90020 (3) Available for stainless steel panel welding (E.g.
