  3. Laser welding different grades of stainless steel?

    May 16, 2008 · Laser welding (especially pulsed welding) has propensity to form cracks in 316 SS. The main source of crack formation is the solidification mode. If the melt solidifies as primary austenite, the austenite phase has low solubility for impurities and rejects them; the impurities (sulphur and phosphorous) then form low melting phases with Fe and lead to cracking.
