a laser beam with the electric arc kombinierendes welding technology and device with a abschmelzbaren electrode assembly of aneinanderstossenden metallleitungen to the formation of rohrleitungsrohren metal

摘要

The invention concerns a welding device and a welding method, in particular of tubular parts (c1, c2) such as abutting metal conduits to form pipeline metal pipes, which consists in effecting the penetrating pass from outside. The invention is characterized in that it consists in creating a single liquid weld metal under the simultaneous action of at least one laser beam (1) transmitted by optical fiber and at least one electric arc protected by gas generated from a consumable electrode (2a) constituting the filler material. The invention is mainly applicable to the construction of pipelines.
