Abstract
Increase in applications of aluminum alloys in all sectors of industry tends to develop new technologies for joining of aluminum without affecting the properties of metal. In present work joining of aluminum 6061 has been done by using the newly developed the microwave welding technique. Microwave Joining of aluminum has been successfully achieved without formation of cracks, burn through and distortions defects, which are otherwise very difficult to control. A domestic microwave working at 2450MHz frequency and at 900w power load was used for joining. For joining process aluminum powder with 99.9% purity and 5μm in size was used as bonding agent between two metal pieces. Structural and mechanical properties of the joined samples were observed through different testing techniques like Vicker’s harness test, porosity and tensile, SEM and EDS. The observed result for microhardness shows 87±8 Hv. The fractured sample during tensile testing shows an ultimate tensile strength of 142MPa with 14% elongation.
