Abstract
A method of fabricating a piston for use in an automobile by welding. The head section and the skirt section of the piston are separately fabricated by casting such that these sections form the top wall portion of the piston when joined together and that the abutting surfaces of these sections form a portion of an oil circulating passage. Then, these sections are connected and welded together using an electron beam.
