  • What is high frequency (HF) induction welding? TWI

    High frequency induction welding is used to make pipe or tube from strip which is fed into rolls which form the strip into a cylindrical shape. The faying edges are brought together between squeeze rolls to produce a V at the point of welding, with an included angle of typically 2-5° for steel. A high frequency coil introduces current into the tube

  • Numerical simulation of high-frequency induction welding

    2 Mathematical model of induction welding The high-frequency induction welding of steel tubes occurs in two stages: electromagnetic heating followed by mechanical joining of the tube edges. It is a multi-physics problem because of the electro- magnetic, thermal, mechanical and metallurgical phenomena taking place during the process.

  • HFI welding Mannesmann Line Pipe GmbH

    Mannesmann Line Pipe uses the high-frequency induction (HFI) resistance pressure welding technique for longitudinal welding. The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high-frequency inductor consisting of a metal coil with single or multiple windings. As a result, high-frequency ring current is induced into the pipe that closes preferably at the strip edges which converge in the welding point. The temperature required for welding

  • PRINCIPLES OF HIGH FREQUENCY INDUCTION TUBE WELDING

    A typical induction welder uses 12,000 to 15,000 volts at 10 to 50 amps. A high frequency transformer reduces this to a lower voltage which is applied to the work coil. A tube mill is not a good enviromnent for high voltage equipment, so vacuum tube welders require more maintenance.

  • Induction welding Wikipedia

    Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio-frequency electric current. This generates a high-frequency electromagnetic field that acts on either an electrically conductive or a ferromagnetic workpiece.
