Abstract

In the TIG and MIG welding of aluminium, high-purity argon or high-purity argon/helium mixtures are used as the inert gas. In order to improve the welding process and the result obtained, the invention proposes that 80 to 250 vpdm, preferably 120 to 180 vpdm, of N2/N2O are added to the inert gas. Any ratio of N2 to N2O may be used.
