Ultrasonic welding technology is a joining method that utilizes localized frictional heat. Since the heat does not spread outside joint, it can efficiently join two materials while minimizing thermal damage to surrounding materials, making an advantageous process for dissimilar materials. In this study, effect of indentation on ultrasonic characteristics A1050 aluminum alloys and C1100 oxygen-free copper was investigated. The changes in energy, tensile shear strength, depth were observed as time increased applied clamping pressure amplitude fixed. experimental results showed strength weld proportional within certain range, but if becomes excessive, local material occurs, which actually reduces strength.
