EFFECT OF PARAMETERS ON WELD STRENGTH DURING ULTRASONIC WELDING OF AL-AL STRIP
Keywords:Ultrasonic, USW, Weld strength, Thickness ratio
This paper describes an experimental study on ultrasonic welding of Aluminium. Ultrasonic Welding (USW) is an upcoming joining process which is expected to replace old techniques due to its speed and Weldablity. Weld strength is an effective attribute to identify the quality of ultrasonically welded joints. In this study the relation between Weld strength and other welding parameters has been studied. Taguchi’s L27 orthogonal array has been used for the experimentation. Using Signal to Noise (S/N) ratios optimal combination of input parameters have been identified. Further to identify the level of significance of process parameters, ANOVA has been carried out on S/N ratios. It has been concluded that pressure is the most significant factor for USW of Aluminium.
