Finite element analysis of case box tape sealer mechanism

Aluminium and its alloys have been used in recent times due to their light weight, moderate strength and good corrosion resistance. The aluminium alloys requires special tool and skill to weld due to high thermal conductivity. In this paper, mechanical properties of the 6061 aluminium alloy single V butt joints welded using ER4043 filler metal with a gas tungsten arc welding (GTAW) were studied. An aluminium alloy plate of 6mm thickness has been selected as specimen. The aluminium welded joint specimens were prepared using the (GTAW) processby different welding parameter values. The input parameters welding current, filler rod diameter, bevel angle, gas flow rate were varied according to full experimental design. Experimental work included tensile test and hardness test on both welded and unwelded specimens. The values of mechanical properties are affecting the mechanical properties of 6061 aluminium alloy specimen joints. GTAW exhibited lower tensile strength, hardness than the parent metal.
