The iRW series is a servo ultrasonic rolling welding machine developed by DONGHO, clean, precise and can generate ultrasonic wave continuously. Aluminium and copper foil welding can be carried out at a high speed of 22 metres per minute. The iRW actuator is controlled by a servo motor drive and the ultrasonic transducer and rotor rectifier are driven by a high steel tapered roller bearing ring for stable rotation in both directions,with a flat welding surface and low internal resistance, ensuring excellent heat transfer after welding. Continuous fusion of different non-ferrous materials with each other, low energy consumption and precise monitoring of welding data.

The iRW series ultrasonic rolling welding machine can be used for battery anodes, pole lugs, solar superconducting heat pipes, solar collector plate welding, aluminium-plastic composite tube welding, copper tube welding, etc.
