Title:
METHOD FOR FRICTION WELDING AND APPARATUS FOR CARRYING OUT THE SAME
Document Type and Number:
Japanese Patent JPH04224087
Kind Code:
A
Abstract:

PURPOSE: To decrease tensile residual stress by controlling a heat cycle of friction welding through supplementary heating with joint use of a means of induction heating.

CONSTITUTION: A thermal cycle at a friction welding part of two member parts 1, 2 to be welded by use of supplementary heating with a means 5 of induction heating is controlled. After an operation of friction welding is finished, further the supplementary heating is continued for a prescribed time. The induction heating means is constituted of an inductor comprising a water cooled single coil surrounding the member to be welded. Thereby, an operation capacity of the welding machine is improved.
