Abstract

In this work, joining of 4014 ALUMINUM tube to 7075 rod is studied using MAGNETIC PULSE WELDING process. The effect of impact angle (4, 6 and 8 degrees) and welding voltage (6 and 7 kV) on the joint are investigated. The microstructure of the weld cross section was evaluated using optical and scanning electron microscopy and mechanical properties of the welds were evaluated by micro hardness and tensile tests. The results showed that, for the impact angles of 4 and 6º, the increase of welding voltage from 6 to 7 kV, leads to the change morphology of interfacial from straight to wavy. While, for the impact angle of 8o, the increase of the welding voltage increases LOCAL MELTING and results in the degradation of the interface. At the same angle, increasing the welding voltage increases the hardness due to the higher work hardening and severe plastic deformation. On the other hand, the effect of welding voltage on the hardness is dominant compared to the impact angle. The results of the tensile test showed that, for the low impact angles, increasing the welding voltage increases the SHEAR STRENGTH, while, for the higher impact angles, it decreases the SHEAR STRENGTH because of creating holes in welding interface. The results showed that joining of ALUMINUM tube/rod with impact angle of 6º and welding voltage of 7 kV leads in uniform and wavy interface with higher SHEAR STRENGTH in comparison with other conditions.
