[0016] The present invention is a method for controlling the clearance of a laser-welded plate based on an exhaust pipe. The thickness opening of the material opening is set at intervals. The thickness opening is open on the thinner side of the material. The area of the binder surface is correspondingly larger, and the corresponding part of the die and punch is correspondingly smaller. Using the punch makes the laser melting During the welding process, there is a gap between the clamped outer plate and the inner plate in the overlapping area. The mold structure is used to form the weld part first to control the movement of the weld, and a reasonable reinforcing rib is designed near the weld. The mold structure first shapes the weld area to control the movement of the weld. The punch is formed by stamping again on the stamped inner plate with a punch and a die. The welds are straight lines. The punch is on the outer surface of the inner plate. In this embodiment, a punch i...
