摘要：
For MIG welding, either in a spray mode without current modulation or in a pulsed mode, of aluminum and aluminum alloys, with the use of a gas shield for at least part of the welding zone, the gas shield is a gas mixture consisting, by volume, of from 0.01% to 1.80% oxygen and from 15% to 98.2% helium, and any balance being argon.
