, China)Abstract:The electron beam welding was performed on 10 mm thick 2A14 aluminum alloy sheets. Metallography and scanning electron microscopy were used to study the weld microstructure. The microstructures of different sites in the weld was employed to compare and analyze the structure distribution in weld-bead. The results show that electron beam (EB) welding 2A14 Al alloy establishes......
