An argon TIG welded joint of the Al – Zn –Mg – Cu alloy was studied. Based on the hardness and differential scanning calorimetry studies, a post-weld alloy heat treatment regimen has been proposed to ensure a welded joint strength of 622 MPa versus the strength of the base metal of 676 MPa. The post-weld heat treatment provides for a two-stage solid solution treatment (470°C, 90 min + 500°C, 20 min) and artificial aging at 120°C for 24 h.
