ABSTRACT:
A bulge (12) formed by coldwelding two wire sections (10-11) is removed by advancing the wire through a bore (91) formed in a split cutting tool (64) having a pair of stepped-back tapered surfaces (92,96) at one end. The tapered surfaces terminate along a diameter of the bore to form a pair of spaced semi-elliptical cutting surfaces (93,97) which are successively rendered effective to remove semi-circular sections of the bulge. The apparatus includes facilities (31,32) for temporarily holding the wire in place within the cutting tool (64) and a clamping arrangement (35,36) for securely holding the wire during the weld bulge removal operation.
