METHOD AND APPARATUS OF FRICTION WELDING TO INCREASE TENSILE STRENGTH OF WELDED WORKPIECE |
摘要 |
A friction welding method includes a step of friction welding a first workpiece and a second workpiece together by pressing the first workpiece against the second workpiece relatively while rotating the two workpieces relatively, and a step of annealing the friction welded workpiece at a position adjacent to a welded portion thereof with high frequency induction heating. A friction welding apparatus is provided for friction welding a first workpiece and a second workpiece together by pressing the first workpiece against the second workpiece relatively while rotating the two workpieces relatively. The friction welding apparatus includes a high frequency induction heater for annealing the friction welded workpiece at a position adjacent to a welded portion thereof with high frequency induction heating.
