Numerical and experimental study for electron beam welding process of Al6061-T6 material

Abstract Joining the aluminium 6061-T6 alloy (Al6061-T6) using Electron Beam Welding (EBW) wais important, especially in aerospace. Although EBW method has been used for different materials literature, there are a limited number of studies Al6061-T6 alloy. The study aimed at weldability and welding quality plates by experimentally numerically technique. A numerical model generated to obtain appropriate voltage, beam current, speed parameters simulate process instead hit trial method, which is costly. based on user-defined function heat source as temperature, material properties. validation compared obtained width from experimental work. Three parameter sets were employed with model. determined according most suitable processing that emerged model, carried out. Experimental showed defects microstructure due unsuitable parameters. While mechanical strength was 70% tensile performance main material, elongation 75%. microhardness affected zone measured 84% base hardness reduction 40% also observed fusion zone. In addition, it proper set can eliminate such defects. application post-weld treatment procedures effectively improve properties could be investigated future studies.
