Sahoo, Ajitesh (2015) Study on Ultrasonic Welding of Aluminimum Sheets. BTech thesis.
Ultrasonic welding is used to weld thin sheet metals of similar or dissimilar couples of non-ferrous alloys like copper, aluminum and magnesium without addition of filler material resulting in high quality weld; it can count on a low energy consumption and on a joining mechanism based on a solid state plastic deformation which creates a very homogeneous metallic-structure between the base materials, free from pores & characterized by refined grains and confined inclusions’ Ultrasonic metal-welding can join also painted or covered sheet metals. Thin sheets of aluminium have been joined by means of Ultrasonic spot Welding. Results are particularly effective in order to evaluate the relevance of various phenomena influencing the lap joint technique obtained on thin aluminium by the application of Ultrasonic Metal Spot Welding (USMSW). The Present study considers the experiments carried out on the aluminum sheets joints at room temperature. The aim is to evaluate the factors influencing the lap joining technique, allowing a deep understanding of the phenomena and the possibility to keep them under control. In this project, the ultrasonic welding of aluminium sheets are carried out under different amplitude, weld pressure & weld time and their effect on tensile strength of ultrasonic welding is analyzed.
