Abstract
Ultrasonic welding is a metallurgical bonding process, which can bond metals together in the solid state. In ultrasonic welding experiments, an SUS436L thin sheet with a thickness of 0.7mm and an SUS304 thin wire with a diameter of 0.2mm were joined. Results indicate that the stainless steel thin wire and sheet can be joined with high efficiency with a strength greater than the shear strength of the material under a short welding time of approximately 0.3s.
