Materials
Can you laser welding stainless steel?
Quick answer
Yes — excellent — minimal discolouration. Laser on stainless steel: match technique to the material; filler ER308L.
The verdict and why
Excellent — minimal discolouration. Low thermal conductivity but retains heat: lower amps (~10% under mild steel), faster travel, or it sugars and distorts
Watch-outs
- dedicated stainless brushes and discs — carbon steel contamination causes rust later
