Abstract

PURPOSE: To form a chain link through one time of welding by butting a pair of U-shaped links formed by curving a round steel bar to each other and welding these simultaneously.
CONSTITUTION: A round steel bar of length half that of a round steel bar forming a conventional chain link is heated and is curved at the intermediate part, whereby a U-shaped piece 11 is formed. With one 11a of a pair of such U-shaped pieces 11 held detained through an existing link 12 and both end parts of the other 11b held butted to the respective end parts of the 11a, a stud 13 is located in the position where its both end parts match the butt parts, then these three are welded simultaneously by electric resistance welding, more preferably electron beam welding, whereby a chain link 14 connected to the existing link 12 is formed.
