Abstract
Two workpieces are frictionally welded by a friction welding apparatus which comprises a fixing holder and a rotary holder. One of the workpieces are held by a fixing chuck provided on the fixing holder, while the other is held by a rotary chuck provided on the rotary holder. Pressing portions are formed on opposing surfaces of the chucks. When the work pieces are pressed by the holders and welded to each other with friction heat, burrs generated around a bound portion of the workpieces are prevented by the pressing portions from expanding axially of the workpieces
