After welding, the inside of the carbon steel stainless steel composite plate (4) is a stainless steel layer (42), and the outside is a carbon steel layer (41). The welding method is arc welding, resistance welding, laser welding, electron beam welding, friction welding, plasma welding or brazing; The welding material is (E71T-1) φ2.5 low-alloy welding wire, the current is 170-180A, TIG base is self-melting, the upper layer is covered with 5-6 layers of gas shielded welding, each layer is 3-4mm thick, the current is 190-200A, and after each layer is covered, the oxide scale is removed with a wire brush before stacking the next layer.
