two more welding processes in sheet metal fabrication


In past post of this blog, we have already considered TIG, MIG, SAW, SMAW. These are perhaps the most common welding processes used for sheet metal fabrication.

But, we cannot skip the following two:

Plasma Arc Welding (PAW): Plasma Arc Welding is a welding process that uses a focused plasma arc to melt the base metal and join metal components. It is similar to TIG welding, but the plasma arc is more tightly concentrated, allowing for higher welding speeds and deeper penetration. PAW is suitable for sheet metal fabrication where precision and control are critical, and it can be used to join a variety of metals, including stainless steel, aluminum, and titanium.

Resistance Spot Welding (RSW): Resistance Spot Welding is a welding process that uses electrical resistance to create heat and join metal components. It involves clamping two or more metal sheets together and passing a high electrical current through the sheets at the desired weld points, creating heat that melts and fuses the metal. RSW is commonly used in sheet metal fabrication for joining overlapping sheets or metal parts, such as in automotive and aerospace industries. It is a fast and efficient welding method that does not require additional filler material, making it ideal for mass production and high-speed assembly.

Both PAW and RSW have their advantages and limitations, which we will cover in following posts. The choice of the welding method depends on various factors, including the type of metal being used, the desired weld quality, and the specific requirements of the project.

We will review these two in more detail soon!
