Laser oscillation-assisted cold metal transfer hybrid welding was conducted on 2.0 mm thick 6082 and a new 6xxx aluminum alloys. The influence of wire composition onmicrostructure and mechanical properties of the 6082 and new 6xxx alloy joints is studied.Our results show that, due to the difference in surface tension, the cross section of a jointfilled with ER4047 wire typically presents a wider U-shape profile, while the ER5183 filledjoint shows a relatively narrower V-shape profile.
