In this study, an electron beam welds produced in a spray-deposited Al-8.6Zn-2.6Mg-2.2Cu (wt,%) alloy were characterized by optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM) and tensile tests. It is found that the joint of the alloy contained three distinctive regions, i.e. fusion zone, heat affected zone and base metal region. Tensile properties of the joints were obtained by testing flat transverse tensile specimens, and the results indicated that tensile strength of these welds approached 82.3~85.3% of the base metal.
