The invention relates to a welding method of a titanium-steel bimetal composite plate. The welding method comprises the following steps of S100, machining and treating a welding groove, specifically, S101, machining the groove; S102, cleaning the groove; S103, assembling the groove; S200, welding a base layer; S300, filling and welding a transition layer; and S400, welding a covering layer. Compared with the prior art, the welding process can be effectively guaranteed to be smoothly conducted, the welding quality is effectively guaranteed, the cost is reduced on the premise that the welding quality is guaranteed, welding is completed in a multi-channel overlapping mode, the welding residual stress is low, the welding quality is high, the welding process limitation is small, actual production and application are facilitated, and the problems that the titanium-steel bimetal composite plate is high in welding cost, low in welded joint quality, poor in weld forming and low in welding efficiency can be solved. 本发明
