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.
