  • Electric Resistance Welded Tubing Industrial Tube and Steel

    Electrical resistance welded tubes are produced from a hot rolled scale-free strip which is formed by rolls at room temperature into a tubular shape. Welding takes place as an electric current heats the two edges of the strip as they are pressed together. Only a narrow band of metal is heated while the rest of the tube remains at room temperature.
