Methods for Welding Stainless Steel
Stainless steel is a popular welding material that is utilized in a variety of industrial applications. While it is not as difficult to weld as some metals, stainless steel has specific properties that present a unique set of challenges. As a leading provider of complete fabrication and welding services, the team at LWS Manufacturing & Welding knows that there are several effective methods for welding stainless steel. That is why our team has compiled some information on 3 of the most common methods to help you determine which is best for your project.

3 Common Welding Methods for Stainless Steel
The following methods are commonly used when welding stainless steel:
1. TIG Welding
TIG (Tungsten Inert Gas) welding is named for the tungsten electrode and the inert gas sheathing surrounding it. With this method, the non-consumable tungsten electrode delivers the current to a welding arc. TIG welding is ideal for critical joints, making it a popular choice for fine and precise welds. It is also the most common method for welding thin stainless steel sections on thinner metals due to the low electrode wear, pore-free welds, concentrated heat source, precise control, stable arc, and lack of oxidization residue, resulting in a simplified cleaning process after the job is done.
2. MIG Welding
MIG (Metal Inert Gas) is a popular welding process that uses electricity to melt and join pieces of metal together. The primary advantage of MIG welding is that it allows the metal to be welded at faster speeds than traditional stick welding techniques. The MIG welding method produces long and continuous welds faster, making it a great choice for thicker stainless steel that requires a long weld line. Since the shielding gas protects the welding arc, this type of welding produces a clean weld with very little splatter, enhancing appeal for the final product.
3. Resistance Welding
Resistance welding is the process used for spot and seam welding. When an electrical current is sent through an electrode and encounters metal, resistance heat is produced to create a “nugget”, or round metal joint. When compared to other methods of welding, resistance welding can be much more efficient for manufacturing as the process can be mechanized and automated, eliminating the required hours of pre-service training for welders. This allows you to create high-quality welds while enhancing productivity, reducing costs, and creating fewer fumes for a healthier working environment.
