Abstract
The 5083 aluminum alloy sheet was welded by metal inert gas welding with zirconium-containing Al-Mg alloy welding wire as filling material. Then the post-weld heat treatment was carried out at 130 °C for 3 hours and 320 °C for 1 hour, respectively. The results show that the effects of two annealing treatments on the MIG-welded Al-Mg joints are basically equivalent. After heat treatment, a large number of Al3Zr particles are precipitated in the...
