Thin-wall titanium plate flat butt welding equipment and welding method

The invention relates to the technical field of titanium plate welding, and discloses thin-wall titanium plate flat butt welding equipment and a welding method.The equipment comprises a rack, a core column, a lifting driving device, a pressing device, a welding machine and a sliding driving device.In the working process, a weldment is positioned and centered after being fed; argon is introduced into the ventilation cavity, and cooling liquid is introduced into the cooling pipe; and then the welding machine is driven by the sliding driving device to move from one end of the connecting seam of the two welding pieces to the other end of the connecting seam of the two welding pieces, flat butt welding of the two welding pieces is achieved, the welding efficiency is high, in the welding process, argon in the ventilation cavity is conveyed into the welding groove through the ventilation holes, the effects of removing impurity air and cooling the back face of the welding seam are achieved, and the welding quality is
