3 Common Methods for Welding Stainless Steel

Welding stainless steel takes serious know-how.

Are you looking for metalworking services that can handle stainless steel? There are several types of stainless steel commonly used today that including austenitic, martensitic, and ferritic, for different applications. Each application takes training and experience to do right. Take a look at the various types and what it takes to weld them properly.

  • Austenitic - this is the most common type of stainless steel used in the metal fabrication industry to make automotive, housewares, industrial, and food and beverage equipment.
  • Martensitic – this type of metal is less chemical-resistant than austenitic, and its application is most common when there is a need for hard steel in the manufacturing of items like sharp-edged tools such as knives.
  • Ferritic - this magnetized stainless steel is full of chromium and is common in the automotive and industrial industries.

What Are the Methods Used for Welding Stainless Steel?

The methods used for welding stainless steel vary depending on the type of metal used. The three welding methods most commonly used on stainless steel are:

  • TIG Welding - TIG (Tungsten Inert Gas) welding works best with thin material due to the low output of heat by the welding torch. The tungsten serves as a conductor to create heat to melt the metal and seal it. The use of filler material is optional, depending on the type of weld you need.
  • Spot Welding - spot welding is also called resistance welding. It uses an electrical current to produce heat and melt the stainless steel. The welding machine presses down on the material and sends an electric current through it to heat it until it melts to the degree required for the weld. This method allows for the precise position of the weld for your project.
  • MIG Welding - MIG (Metal Inert Gas) welding is the most common one used when you need a filler to complete the weld or seal. The filler is continuously fed through the welder as the stainless steel gets fused.
