How to Weld Stainless Steel: Tips and Tricks

Stainless steel is a popular metal to weld for creating physical structures because of its durability and longevity. The high chromium amounts in stainless steel make it more resistant to rain and bad weather.  

However, welding stainless steel requires advanced techniques and tricks to do it successfully. Therefore, beginner welders should take note of the tips and tricks outlined below for welding stainless steel.

 

Tips and Tricks for Welding Stainless Steel

High heat levels can cause stainless steel to warp because it retains heat efficiently. That is why welding stainless steel is more challenging compared to other metals. If you’re not careful, the stainless steel material will become distorted after you try to cool it off. For this reason, use a low level of heat whenever you weld stainless steel.

Begin the weld on a cool setting and gradually add more heat to see how well it welds the metal. Since stainless steel usually consists of thin metal sheets, temporary tack welding is needed to align the sheets and prevent warping. This welding must be done in short 3 to 4-second welds, with time to cool off between each attempt. 

Now choose between stick, MIG, or TIG welding to finish the weld and make it permanent. The best option for amateurs working on stainless steel is MIG welding, as long as you don’t care about the structure’s aesthetics. Just be careful with the heat because if the chromium content in the steel gets destroyed, the steel will be susceptible to rust.
