Service life of ultrasonic metal welding machine

The service life of a welding head depends on two aspects: first, material and second, process

Materials: ultrasonic welding requires metal materials to have the characteristics of good compliance (small mechanical loss in the process of sound wave transmission), so the most commonly used materials are aluminum alloy and titanium alloy. However, ultrasonic metal welding requires wear resistance of welding head (requiring high hardness), which makes the selection of materials more difficult, because hardness and toughness seem to be naturally opposed, This requires us to choose materials with very high requirements. The high-quality steel materials we choose can better solve this contradiction and improve the effective life of the welding head as much as possible.
