Sheathed welding wire for electric arc welding without slag in particular for applications calling for welding in a descending vertical position

摘要

A sheathed wire, for welding without slag, comprises an external metal envelope and some filler elements. The filling elements contain iron and represent 8 to 27 wt.% of the filler elements. The total quantity of calcium contained in the wire represents 100 ppm to 0.14 wt.% of the total mass of the wire or 0.035-1.9 wt.% of the mass of filler elements : Independent claims are also included for : (1) arc welding with this sheathed wire; (2) a weld joint or metal deposited by arc welding with this sheathed wire; and (3) a metal component incorporating a joint welded by this method.
