Abstract
At least two workpieces are provided and an intermediate member is arranged as a filler between opposed end faces of the workpieces. The workpieces are pressed against each, other via the intermediate member to produce friction pressure therebetween while rotating or vibrating the intermediate member at a high speed. Then, each workpiece is upset to the intermediate member on bringing the rotation or the vibration of the intermediate member to a halt. Thus, the workpieces are easily and securely joined without causing any defects.
Claims9
A method of joining at least two workpieces at their end faces by friction, filling welding, said method comprising the steps of:
- arranging an intermediate member as a filler between opposed end faces of the workpieces,
- pressing said workpieces against each other via the intermediate member to produce friction pressure therebetween while rotating or vibrating the intermediate member at a high speed, and
- upsetting said workpieces to the intermediate member on bringing the rotation or the vibration of the intermediate member to a halt.
