Features, Advantages and Disadvantages of Friction Welding
    Eco-friendly
  • Minimize energy consumption
  • Minimize harmful substances such as smoke, gas, fumes, dust, etc.
    Quality Improvement
  • High reproducibility and stable connection strength
  • Less thermal transformation yet high dimension precision
  • No pores on welded part
    Cost reduction
  • No need of electrode, solvent, or extra bevelling and processing
  • Able to connect dissimilar or nonferrous metal
  • Save costs of material, processing and forging
    Improvement of Productivity
  • Short welding time and great work efficiency
  • Easy control - minimal operator training required
  • Automatic operation is possible with the automation eqiupment attached.

Features, Advantages and Disadvantages of CNC Friction Welding
    Improvement of Productivity
  • Reduce non-working time by improvement of control and speed by servo motor
  • Higher operation rate from not being affected by temperature change of hydraulic oil
  • Reduce machine setting time by automated movement of stopper depending on the length of material
    Quality Improvement
  • High precision welding by a servo processing (servo motor and ball screw) of friction welding thrust
  • Improve quality problem from surrounding temperature that happens in hydraulic type
  • Easy welding of difficult products by servo processing of principal axis motor
    Cost Reduction
  • Reduced non-working time shortens the cycle time.
  • Servo motor runs only in the operation and causes high energy efficiency.
  • Smaller hydraulic tank reduces an installation space.
    Eco-friendly
  • Smaller amount of CO2 emission than hydraulic type
  • Small hydraulic tank causing less waste oil and noise
