MIG welding method for Al alloys with Ar/He/O2 protective gas |
| 摘要 |
<p>Metal Inert Gas (MIG) welding in a spray regime without current modulation or with a pulsed regime, of aluminum and aluminum alloys, with gaseous protection in at least a part of the welding zone uses a protective gas that is a mixture of, by volume, 0.8-1.8% oxygen and 15-98.2% helium, the balance being argon. Preferably, the protective gas mixture contains at least 1% of oxygen.</p> |
