Stainless steel welding requires distinct WPS + welder + procedure due to stainless characteristics: (1) sensitization + chromium carbide precipitation (Cr23C6) reducing corrosion resistance; (2) austenitic + duplex + ferritic + martensitic families with different weldability; (3) thermal expansion 50% higher than carbon steel causing distortion; (4) protective gas + heat input control critical; (5) post-weld cleaning + passivation for corrosion resistance restoration.
