  • Description
    • Friction welding, a method known for its solidity, employs mechanical friction and axial pressure to generate surface heat. This process places the material in a semi-melted state, allowing the workpiece to be firmly welded together under pressure. It effectively joins identical or different metals into a unified structure.
    • To establish a low-carbon society, it is crucial to conserve energy during welding. Reducing heat input prevents splashes and smoke formation at the joint, eliminating the need for extra materials or fillers. This presents a revolutionary shift in your manufacturing approach.
    • In Taiwan's construction industry, the "Friction Welding" method has been a tried-and-true technique for many years. The process includes warm-up, normal pressure, and forging pressure steps. The traditional use of two hydraulic cylinders as the pushing driver tends to cause variations in oil temperature, leading to a notable decrease in success rates.
    • Construction has long embraced the effectiveness of the "Friction Welding" technique. Our patented "Friction Welding Machine with Servo Mechanism" incorporates a servo motor to drive a screw, converting traditional hydraulic pressure values into digital data. This evolution allows for the production of consistently high-quality, well-coupled rebar, greatly enhancing the structural integrity of buildings while surpassing government safety regulations. Additionally, our technology eliminates human errors commonly associated with inexperienced workers. Once verified data is entered, our machine takes charge of the subsequent processes autonomously.

    • Employing the most recent servo drive, our rebar friction welding machine enhances welding efficiency, providing a quicker and more precise operation. The full touch panel offers enhanced flexibility, adaptability, and a high degree of freedom. It can be equipped with a cutting device and driving pushing structure supported by an automatic cutting waste servo motor. Utilizing friction welding in the production process ensures numerous benefits, including heightened process efficiency, increased productivity, excellent joint properties, and safe working conditions.
    • Friction welding offers a cost advantage in coupler production over forging, with the added benefit of swift formation. The strength of friction-welded products equals that of their forged counterparts, and the resulting surface is noticeably cleaner.

  • Principle
    1. Unique welding function
      Fusing the welding surface to the two end faces of the metal results in a joint characterized by formidable toughness. The tensile and torsional strength of this joint far outstrips that achieved through arc welding and argon welding.

    2. Adding dissimilar materials can reduce material costs
      Friction welding provides a solution for joining metal combinations that are incompatible with traditional welding methods. This innovative approach not only saves costs but also serves as an effective method for lightweight component applications.
    3. Improve welding accuracy
      Post-welding, the materials at both ends exhibit minimal deformation, and the center eccentricity is held within 0.5m/m. This commitment to workpiece quality results in reduced machining allowances and lowered material and processing costs.
    4. Eco-friendly and energy efficient
      Avoid the use of materials or fillers like metal, flux, gas, etc. Achieve uniform heat without arcs or toxic byproducts, effectively enhancing the overall work environment.
    5. Faster and more accurate welding efficiency
      The cost of production using friction welding is less than that of forging, and it enables rapid formation. The strength achieved is equivalent to forged products, and the resulting surface is notably cleaner.
    6. Can eliminate manual welding errors
      Through the use of machine-controlled friction welding, the process attains uniformity and repeatability, eradicating the potential for human error. Concurrently, it achieves welding quality that is independent and exceeds the technical proficiency of the operator.
  • Features

    a. The fusion of the welding surface at both ends of the metal results in a robust and resilient connection, with tensile and torsional strength surpassing that of arc welding and argon welding.

    b. Diverse materials can be welded together, such as stainless steel with various medium and high carbon steel materials. However, annealing is necessary after welding high carbon steel. Post-welding, the materials at both ends maintain minimal deformation, with a center eccentricity difference within 0.5m/m. This ensures workpiece quality, reducing the need for processing allowances and lowering material and processing costs.

    c. Friction welding offers cost-effective production, lower than that of forging, and allows for swift formation. Despite this, the strength is comparable to forged products, and the resulting surface is cleaner.

    d. Friction welding eliminates the need for expendable materials like fuels or metal-filled solvents, gases, etc. The process generates uniform heat through friction between the contact surfaces, avoiding arcs or toxic materials and contributing to an improved working environment.

  • Advantages of servo control

    Achieving stable operation without being influenced by oil temperature fluctuations, our system enables high-precision welding. Angle control further broadens the applications of friction welding, extending to phase-adjusting workpieces. The implementation of servo control not only enhances energy efficiency but also reduces carbon dioxide emissions compared to hydraulic control, making it an eco-friendly option. With no oil leakage, the working environment is improved, and the absence of waste oil contributes to environmental preservation. The feedback control of forge force ensures smooth operation at low speeds, and the downsized hydraulic unit results in space-saving and reduced noise.
