Clean the joint area with a stainless steel brush and a dedicated cleaner to remove oils, mill scale, and oxides. Masking off adjacent surfaces prevents carbon steel splatter from contaminating the stainless.
Effective MIG Welding Stainless Steel Masking Techniques
Back purging with argon for root passes or inside diameters dramatically reduces internal oxidation and produces cleaner, stronger joints. Excessive heat input can burn off the chromium, creating weak, rust-prone welds, while too little heat leads to poor fusion and lack of penetration.
For most stainless steel mig applications, a mixture of argon and oxygen is standard. Wire feed speed typically ranges from 200 to 400 inches per minute, adjusted until the arc sounds smooth and the bead looks consistent.
