ABSTRACT:
A friction welding machine for welding first and second tubular workpieces together comprises a workhead assembly having a rotatable chuck for forcefully displacing the first workpiece into frictional engagement with the second workpiece. The workhead includes a shear mechanism having a shear tool mounted for selected displacement along the chuck's rotational axis. A shear cylinder of the shear mechanism positions the shear tool at a selected ready position within the first tubular workpiece preparatory to a welding operation, advances the shear tool upon completion of the welding operation into the second tubular workpiece thereby shearing the freshly formed internal weld flash, and retracts the shear tool to a remote position after shearing.
