Abstract

Electrical and automobile industries have high demands for an effective joining of dissimilar materials because of their enormous use. In the present research, numerical and experimental investigations have been conducted to study the effect of parameters of ultrasonic spot weld on metal joints for electronic components. Copper and brass alloy sheets have been welded using ultrasonic spot welding in the lap configuration. Regression analysis in combination with analysis of variance has been applied to formulate the models. Based on the optimum condition determined for the input parameters, mechanical and microstructural analysis is performed using tensile testing and SEM analysis, respectively. Finite-element modelling (FEM) simulation is conducted for the temperature near heat-affected zone (HAZ) and fusion zone (FZ). The results obtained from experiments are compared with the simulation results obtained from FEM modelling. Slight variations in tensile properties of the weldments that are free from defects have been observed with increase in welding time and frequency. A close agreement between the experimental and simulated values of FEM has been observed, which establishes the validity of reasonable accuracy of the model.
