Abstract
The invention concerns a method for welding hinge pins onto links each formed of one or more elements, the links being connected to each other by means of said hinge pins arranged in passages provided for this purpose in the links, each pin being fixed onto one of the links and hinged onto the next link, characterised in that the connection of the pin to the link is made via an arc welding operation with the aid of an electrode in an inert atmosphere without using a solder.
