MIG welding method for Ni and Ni-alloys with Ar and CO2 based shielding gases |
摘要 |
A method for the MIG welding of nickel and some nickel alloys, with a protective gas in a least a part of the welding zone, uses a protective gas containing a mixture of 0.05 to 0.5% of CO2 and argon. Advantageously, the gas mixture also contains 15 to 50% vol. and preferably 17 to 30% vol. Helium or 0.1 to 10% vol. and preferably 1 to 7% vol. Hydrogen. Independent claims are included for gas mixtures used as the protective atmosphere for the MIG welding of nickel and some nickel alloys. |
