Abstract (en)

A method of forming a hollow head portion (72) of a piston (14) for a swash plate type compressor, comprising the steps of fixing a closing member (154, 310) to a hollow cylindrical member (158, 200, 300) which is open at at least one of opposite ends thereof, so as to close an open end of the hollow cylindrical member, and applying a welding beam to welding surfaces of the closing member and the hollow cylindrical member, which welding surfaces are adjacent to or in contact with each other, so that the closing member and the hollow cylindrical member are bonded to each other at the welding surfaces, wherein the welding beam is incident on the welding surfaces of the closing member and the hollow cylindrical member in a direction which intersects the welding surfaces. <IMAGE>
