Optimization of Ultrasonic Welding Parameters Based on Response Surface Methodology

Abstract

In this paper, the optimal process parameters for ultrasonic welding of copper wire and aluminum plates are studied using the response surface method. The effect of various welding parameters on the welding effect is experimentally tested. The results are analyzed using the Box-Behnken design to establish a regression model to optimize the welding parameters. The model uses the welding height, welding energy and welding pressure as influencing factors and the welding strength and welding time as response values. The results show that optimal welding of copper wire and aluminum plate is obtained at the height of 2.2mm, energy 1300J, amplitude 85% or 95%. The response surface method used in this paper can provide a reference for the ultrasonic welding of other materials in the study of process parameters.
