  • Introduction to spiral tube processing and welding

    Spiral tube processing and welding: Before welding, thoroughly remove the rust, oil, water, paint, etc. that are harmful to welding, and select the electrode suitable for the steel type. The spot welding time interval is shorter than the carbon steel spot welding distance, and the spiral pipe brush should be used when removing the welding slag.

  • Spiral welding - Wikipedia

    Spiral welding is a process where a continuous full penetration MIG weld overlay is used to rebuild damage from wear, erosion, corrosion or cracking, or to increase the dimensions of a component to match an increased dimension on a mating part. Using the Spiral weld process eliminates the possible distortion of the component due to unbalanced stresses from normal welding processes.
