It is recommended to pre-heat the materials to 200 - 300°C before welding, and carry out post-weld heat treatment at 650°C. Welding can be performed using grade 410 filler rods, but ductile welds can be achieved using grades 308L, 309 or 310 steels. Stainless Steel - welding engineerDuplex stainless steel weldability is generally good, although it is not as forgiving as austenitic stainless steels. Control of heat input is important. Solidification cracking and hydrogen cracking are concerns when welding duplex stainless steels, but not as significant for some other stainless steel alloys.
