Studies and development of ultrasonic welding tools

The article is devoted to the development and the design of ultrasonic welding tools intended for the generation of lengthy seams by the press welding. We solve the problem of the formation of even distribution of vibrations radiating surface, which size exceeds half of the wave length of ultrasonic vibrations in the material of the tool. The dependence of distribution of vibration amplitude along radiating surface of welding tool on the shape and sizes of the tool are revealed. The possibility of the design of the tool with even distribution of vibration amplitude is confirmed by the results of experimental studies on the base of developed vibrating system with welding tool intended for the formation of 220 mm long welding seam.
