Abstract
In the present work, spot welding and weldbonding have been adopted for manufacturing bimaterials. Spot welding parameters namely, welding current, electrode force and welding cycles have been optimized and reported for manufacturing bimaterial (brass-steel) damping sheets. Tensile strength, fatigue strength, microhardness measurements and microstructure examination have been performed and are reported. The present work demonstrates tremendous improvement in fatigue strength associated with weldbonding, when compared to spot welded bimaterials.
