Precautions for bonding welding and bonding welding process

Precautions for bonding welding and bonding welding process

Principle of bonding welding.Bonding welding is also called ultrasonic aluminum wire welding. The principle is to use an ultrasonic generator to generate energy. The magnetostrictive transducer rapidly expands and contracts under the induction of a high-frequency magnetic field to generate elastic vibration, so that the corresponding vibration of the wedge is simultaneously applied to the […]
