Strength Characteristics for Various Spot Welding Conditions in 7075-T6 Aluminum Alloy Sheets

박판 Al 7075-T6재의 점용접시 용접조건변화에 대한 강도특성

With increasing demand of energy saving, -many efforts were made to employ aluminium alloys in the automobile industry. Especially, resistance spot welding has been widely used in the steel metal joining process because of its high productively and convenience. In this paper, spot weldability of 7075-T6 aluminium thin sheets for various welding conditions were examined by series of experiments. The tensile shear strength and microstructure of welded specimens was observed, and The optimal welding conditions were found for each welding conditions.
