Welding performance· High welding speed: High - frequency welding machines utilize the skin effect and proximity effect of high - frequency current. They can rapidly heat the welding area to the melting point in a very short time, significantly shortening the welding time and improving production ef

Ultrasonic Welding1. PrincipleUltrasonic welding uses high - frequency mechanical vibrations (usually above 20 kHz). The ultrasonic transducer converts electrical energy into high - frequency mechanical vibrations. A sonotrode (also known as a welding horn) transmits these vibrations to the parts to
