Welding Mild Steel Stainless. Since stainless steel has low heat conductivity using a welding application that features a shielding gas is perfect for the task. Microstructure to analyze and investigate the weldability of Stainless Steel and Mild Steel sheet.
I need to weld two plates together one 316 mild steel and the other 12 stainless using a wire feed welder and flux cored steel wire or the same welder using an argon shielded solid steel wire. For any of these. 316 would be betterespecially if you wish to leave the weld as a feature.
Ideally using an E309 welding electrode.
TIG welding stainless steel is performed by using a non-disposable tungsten electrode with a TIG welder for striking up the arc. Oil grease general dirt or carbon from an exhaust are all weld contaminates. Keep this in mind if youre repair welding a car exhaust. If the weld is a short bead length.
