Abstract
The invention relates to a process and a unit for the MIG welding of aluminum and its alloys, employing gaseous shielding of the welded zone, composed of a central flow of gas consisting of argon and/or oxygen and of a peripheral gas stream consisting of argon or a mixture of argon and helium. The MIG welding process of the invention allows effective welding of workpieces made of aluminum or aluminum alloys by improving the penetration of the weld and the wetting of the weld bead, that is to say the angle of connection of the weld bead to the welded workpieces.
