Abstract
The method employs CO2 and argon supplied to the welding site separately from, but simultaneously with, each other, the argon being conveyed as a central flow (2) to the melting point (3) of the consumable electrode (3a) to form a plasma arc, and the CO2 being conveyed as a sheath-like flow (4) to the welding site. A welding gun for carrying out the method has a head with a central annular nozzle (6) for the argon and an annular sheath- like nozzle (5) surrounding the central nozzle and serving for feeding the CO2.
