• Description
    • Friction welding is a "solid" welding method. By mechanical friction and axial pressure, the surface heat is generated so that the material is in a semi-melted state, and then the workpiece is subjected to pressure to firmly weld the same or different metals into one body.
    • In order to build a low-carbon society, it is necessary to save energy as much as possible during the welding process. By reducing the heat input, the material at the joint does not generate splashes or smoke, and no additional materials or fillers are needed, bringing new possibilities to your manufacturing field. revolution.
    • The “Friction Welding” method has been a staple of construction in Taiwan for many years. The steps of Friction welding are as followed: Warmup, normal pressure then forging pressure. The traditional method of using 2 hydraulic cylinders as the pushing driver would cause inconsistent oil temperature, which in turn causes the success rate to drop drastically. 
    • Our patented “Friction Welding Machine with Servo Mechanism” uses a servo motor to drive a screw and turns traditional hydraulic pressure values into digital data. Making it possible to produce well coupled Rebar with consistent quality and therefore greatly reinforcing the structural integrity of any building while exceeding government safety regulations. Also, our technology also eliminates any human errors that may be caused by inexperienced workers. And once the verified data have been entered, our machine will handle the rest of the process. 
    • Using the latest servo drive, the welding efficiency of our rebar friction welding machine can be faster and more accurate.
      Our full touch panel can be much more flexible, changeable and high degree of freedom which is able to equipped with cutting device and driving pushing structure by automatic cutting waste servo motor. The use of friction welding in production process ensures such benefits as high process efficiency, high productivity, very good properties of joints and safe working conditions.
    • The coupler cost of using friction welding is lower than that offorging, and it can be formed quickly.Its strength
      is no less than that of forged products, and the surface is cleaner.

  • Principle
    1. Unique welding function
      The welding surface is welded to the two end faces of the metal, and the joint has strong toughness.
      Its tensile and torsional strength far exceeds the strength of arc welding and argon welding.
    2. Adding dissimilar materials can reduce material costs
      Metal combinations that are not compatible with conventional welding can be joined by friction welding.
      It can save a lot of cost and is an application method of lightweight components.
    3. Improve welding accuracy
      After welding, the materials at both ends are not easily deformed, and the center eccentricity is within 0.5m/m.
      Ensuring the quality of the workpiece reduces machining allowances and reduces material and processing costs.
    4. Eco-friendly and energy efficient
      Do not use materials or fillers such as metal, flux, gas, etc.
      Uniform heat, no arc or toxic, can effectively improve the working environment.
    5. Faster and more accurate welding efficiency
      The production cost of using friction welding is lower than that of forging, and it can be formed quickly.
      Its strength is no less than that of forged products, and the surface is cleaner.
    6. Can eliminate manual welding errors
      The machine-controlled friction welding process is consistent and repeatable, eliminating human error.
      At the same time, it produces independent and higher than the operator's technical level of welding quality.
  • Features

    The welding surface is melted together at both ends of the metal, and the connecting point is strong and tough, and the strength of tensile and torsional resistance far exceeds the strength of arc welding and argon welding.

    1. Dissimilar materials can be welded together, For example, the stainless steel material can be welded with ordinary iron materials with various medium and high carbon steel materials, However,Require annealing after completed welding high carbon steel.
    2. After welding, the materials at both ends are not easily deformed, Center eccentricity difference within 0.5m/m,To ensure the quality of the work piece can reduce the processing reservation,Can reduce materials and processing costs
    3. The cost of production using friction welding is lower than that of forging, also It can be formed quickly. However, the strength is not less than of forged products, and the surface is cleaner.
    4. It does not require the use of expendable materials such as fuels or metal-filled solvents, gases, etc., and generates uniform heat with friction between the contact surfaces, so there is no arc or toxic material to improve the working environment.

  • Advantages of servo control

    Stable operation without being subjected to oil temperature. High-precision weld is possible. Angle control expands the range of the application of friction welding such as to phase adjusting workpiece. Servo control reduces more carbon dioxide emissions than hydraulic control dose. Better energy-saver. No oil leakage >>> Improved working environment. No waste oil >>> Environment-friendly. Feedback control of forge force enables smooth drive at low speed range. Uniform output under any conditions (temperature, humidity and so on) Downsized hydraulic unit >>> Space-saving and low noise.
