摘要

The invention relates to a process for an apparatus which automatically, by welding, is attached to a metal construction underwater and a method for automating the realization of a weld joint underwater. The invention is characterized in that the welding electrode 3 is situated in a watertight chamber b, the base 1 of which is constituted by the piece which is to be welded in place and which is partially filled with a burning compound 4. The piece which is to be welded in place has at the site to be welded a thinned material a, which during the welding operation melts and forms with the molten substrate c and with the molten material of the welding electrode a weld joint. The device also incorporates equipment for conducting the welding current to the welding electrode and for igniting the filler compound and the welding electrode. IMAGE
