Most types of stainless steels have good weldability and can be welded with all arc welding processes (GMAW, FCAW, GTAW, SMAW and SAW). Stainless is used in many different applications for its strength, abrasion resistance and corrosion resistance. Unfortunately, many assume it can be welded just like carbon steel. In fact, this is the first [.]

Welding stainless steel can be tricky because it is very good at retaining heat, and this can lead to problems such as warping, embrittlement, and rust. In fact, as little as five amps can make the difference between the perfect weld and a blued or burnt-through part.

For "outdoor" stainless steel welding or cutting, approved respirators must be worn; again, an airline respirator rather than an air-purifying fume respirator provides the best protection. Cal/OSHA construction standard GISO 1537 also regulates the welding and cutting of metals coated with toxic substances, including chromium.

Jun 18, 2020· Stainless steel grows and warps excessively from heat. It also forms the red, blue, and black coloring you're familiar with on welds. The coloring is all from excess heat. Welding will always need heat, otherwise the metals won't weld together, but the heat on stainless steel is from the job heating up more than it needs to.
