Welding defines as a process where two or more pieces of metal or thermoplastics are secured together by use of heat and pressure. This process begins with the application of heat which softens the material and enables it to affix together as one piece in a joint area. The process ends when the welder applies an adequate amount of pressure, and the pieces have become connected.
In the latter parts of the 19th-century welding came into existence and with the onset of the industrial revolution, welding matured and left its cousin known as forge welding behind. Today, the most common form of welding includes resistance or spot welding, or others like an Arc, MIG, or TIG welding that relies on the use gas. Whichever version is used history has shown that electric and gas based flame heating methods have proven to be much safer and faster for welders.
ICR’s repair technicians have the experience and knowledge to repair a multitude of welding equipment used within an industrial manufacturing environment.
Types of Welders ICR repairs:
Resistance welding is a process that utilizes electrically-produced heat as well as the pressure to connect two separate materials. Although these particular processes refer to bonding metals, resistance welding can also pertain to plastic bonding as well. When spot welding correctly it’s considered both efficient and quick. Manufacturers that support this type of welding are Weltronic (WTC), Pertron, Square D, and Degensha.
MIG or metal inert gas welding is a method of welding that uses a gas to shield the weld metal. This process uses the gas to keep the metal from being welding and also exposing it to the natural elements in the environment of the industrial application. This effective form of welding allows the welder to operate at a continuous rate, thus quicken the process. MIG welding does not require an expert level of welder skills. However, the equipment used can only be operated indoors due to the gas involved in the welding process.
TIG or tungsten inert gas welding resembles MIG welding in a way. The main difference between the two forms of welding is that TIG uses a tungsten current form, while MIG’s process uses a metal electrode. Since tungsten uses the method, it requires additional filler placed within inside the welding device. This additional procedure is done because tungsten does not melt during the welding process. The tungsten current form is unique because it can heat to a higher temperature before melting all the other metals. The stainless steel industries work with this type of welding.
Arc or stick welding is a type of welding that has slipped in use within plants. Stick welding known as shielded metal arc welding or SMAW begins as electrodes become self-shielded, and companion equipment isn’t needed. There’s no need for gas, as with other forms of welding.
Wire feeders used within the welding process come in two different types, which are constant speed or voltage sensing. The difference between the two kinds boils down the power sources used by each. Constant speed can only use a CV or constant voltage power supply while voltage sensing wire feeders use a CV or a CC or constant current power supply.
Used with resistance spot welders, water savers help avoid welding tip loss with the ability to sense issues in the welding process. The device compares total inflow and outflow of cooling water being used and is especially useful with robotic welding guns.
Manufacturers ICR supports:
ICR warrants our repairs to be free of defect for a period of one year in service. Unlike the OEM, our warranty doesn’t expire while the part sits on the shelf waiting to be used.
