Abstract

Procédé pour le soudage-MIG au plasma, selon lequel le gaz protecteur et le gaz de plasma sont formés par un gaz de même composition. Un courant de gaz commun est scindé en une colonne cylindrique de gaz de plasma et en une gaine de gaz protecteur entourant le gaz de plasma. A cet effet, la buse de la torche comporte un anneau-électrode central qui fait office d'électrode non fusible et qui, par des ailettes radiales, est lié à un support cylindrique qui assure l'évacuation rapide de la chaleur et qui est fixé sur le boîtier de la torche. Application aux machines à souder.
