ABSTRACT:
A heavy-duty chain link which constitutes a chain for use with vessels and the like. The link is fitted with a stud across the center thereof, which tends to prevent stretching and kinking of the link. Heat sources such as electron beams and plasma arcs fusion weld the abutting of two ends of the link, and the stud is wedged at at least one of its ends to said link by means of roots of weld beads provided by the heat sources. Such wedges lie at a right angle with the axis of the link for most effectively preventing the stretching and kinking of the link when it is subjected to a heavy load. A method of making this kind of stud chain link is disclosed also.
