Steel plates and stainless steel can be welded. Before welding, it is necessary to use an angular grinding wheel to grind off the galvanized layer at the place to be welded. If you are using manual arc welding, use a DC welding machine and use stainless steel electrodes for welding. When selecting welding rods, you must choose austenitic stainless steel welding rods, such as A132, A202, etc. When welding, use as little current as possible, reduce the swing when transporting the bar, hammer the weld bead, release stress, and keep the temperature of the workpiece as low as possible. In this way, welding does not require preheating and can be welded directly with good results. However, it should be noted that if the type 3 pressure vessel is manufactured, these two different materials cannot be welded, and materials with similar performance should be used for welding.
