Abstract
A chain link (1) consists of two loops (2a, 2b) and two sides (3a, 3b), and a post (5) welded in between the chain link's sides (3a, 3b). The post (5) has sections (7) of reduced thickness against the chain link's sides (3a, 3b) in order to produce weld grooves for welding the post (5) to the chain link's sides (3a, 3b) with a through-weld. A sacrificial anode (9) is affixed around the chain link's post (5), by means of casting, welding or clamping.
Claims8
A chain link comprising:
- two loops and two sides, wherein a distance between the loops constitutes a length of the chain link, and a distance between the sides constitutes a width of the chain link;
- and
- a post welded in between the chain link's sides, wherein adjacent the chain link's sides the post has reduced thickness with respect to other parts of the post in
- a direction transverse to a plane of the chain link, in order to produce weld grooves for welding the post to the chain link's sides, and for allowing entire contact areas of the post to be through-weld to the chain link's sides.
A method for manufacturing a chain link including two loops and two sides, wherein a distance between the loops constitutes a length of the chain link, and a distance between the sides constitutes a width of the chain link, and wherein a post is welded in between the chain link's sides, the method comprising:
- providing a post, wherein adjacent the chain link's sides the post has reduced thickness with respect to other parts of the post in a direction transverse to a plane of the chain link, in order to produce weld grooves for welding the post to the chain link's sides, and for allowing entire contact areas of the post to be through-weld to the chain link's sides;
- and
- through-welding the entire contact areas of the post to the chain link's sides.
