DESCRIPTION
VSS-630 is a precipitation hardening stainless steel used for welding of materials of similar chemical composition whose mechanical properties influenced greatly by the heat treatment.
INSTRUCTION FOR WELDING
(1) Keep the arc length as short as possible.
(2) The welding current should be used as low as possible.
