Abstract

Method for welding underwater arc, including the stages of supplying gas to a fixed welding chamber located under water, to create a gaseous environment around the region where the filler metal is to be deposited, and to feed a rod of welding to the arc, continuous and consumable, to the region in which the filler metal is to be deposited, the rod comprising a tubular sheath containing a core in which a metal powder is included.
