摘要

PROBLEM TO BE SOLVED: To provide a punching blade intended to reduce cost through a long time use and a pressure welding machine equipped with this punching blade in the punching shear of a pressure-welded material. SOLUTION: In the pressure welding machine 100 for welding materials to each other by pressure in the axial direction, there is attached punching blade 1 which is made slidable in the axial direction for the purpose of shearing a bulge 63 in the pressure welding zone. This punching blade 1 is provided with a replenishing blade part 12 in the part that comes into contact with the bulge 63; thus, the cost is reduced through the longer service life.
