There are three main ways to learn how to weld stainless steel. Stick welding, SMAW (shielded metal arc ) or GMAW are all common ways to learn how to weld stainless steel.

An arc welder is a much more efficient way to weld stainless than welding mild steel. For arc welding stainless metals, a small gauge of stainless steel electrode is preferred. Like mild steel, there will be a coating of slag on the finished bead. 

However, stainless slag can 'ping' as it cools. An arc machine is an easy way to learn how to weld stainless steel. You can also explore more about stainless steel pipe fabrication at https://tiptigusa.com/stainless-steel-welding-applications/.

TIG Welding is the most difficult method to weld stainless steel, but it's also the most rewarding. It offers a perfect joint between base and filler metal.

Although it requires more skill, the process of using a TIG is very similar to that of the Oxy-Acetylene gases process. To create an arc, tig welders use a small torch with a tungsten electrode. 

Because of its high melting point, tungsten is commonly used. When the tungsten tip is struck against the metal, it creates an arc that starts the fusion process. A filler rod is then added to give the joint more substance.

It all comes down to the right equipment and the best process to learn how to weld stainless. The arc or the MIG process is sufficient for the basic welding of stainless steel. However, if you need a high-quality finish or are building an item such as a commercial food mixer component, the tig welder will be your best choice. You will quickly hire an expert to get the best products.
