Quick overview

Highly Reliable Welding of Aluminum Cables to Copper Terminals

Welds Copper/Aluminum Harnesses, Bus Bars, and Foil Laminates

  • Spring Pressure Sync Mechanism
    Excellent response to the pressure variations prevents slip between horn and work, reduces ultrasonic energy loss and minimizes dust and waste.
  • High Rigidity Pressure Mechanism
    Maintains very small deflections to ensure uniform weld side pressure.
  • Unique, Original Design Ultrasonic Oscillation Frequency Automatic Tracking System
    Ensures stable vibration amplitude during high loads.
  • High Performance Depth Control (1μm Resolution Linear Scale)
    Oscillation is controlled by feedback of sinking of work and work height.
  • 4 Types of Oscillation Control Method
    Time, Work Sinking Value, Work Height, Applied Energy

Principle of Ultrasonic Metal Joining

Unlike resistance welding, the ultrasonic vibration removes oxide film on the metal surface and scatters surface layer impurities in order to create a state of solid-phase welding through the attraction among the metal atoms.
