Abstract
An electric-arc welding process for assembling parts that are components of a motor vehicle, in which a consumable wire is used that is subjected to a cyclic mechanical movement. The wire is moved closer to and then further away from the parts to be welded so as to create a short arc between the end of the consumable wire and at least one of the parts to be joined. In this way, molten metal is deposited in order to progressively produce a welded joint between the parts.
