  • Precautions for welding stainless steel pipe fitting

    Precautions for welding stainless steel pipe fitting

    1. To prevent corrosion due to heating, the welding should not be too long, which is about 20% less than that of carbon steel electrodes. The arc should not be too long, and the layers will cool quickly. A narrow weld bead is preferred. 2. Stainless steel pipe fittings harden quickly after weldin...

  • The difference between fixed welding joints, rotating welding joints, and prefabricated welding joints in steel pipe welding

    The difference between fixed welding joints, rotating welding joints, and prefabricated welding joints in steel pipe welding

    Fixed welding is a welding joint that cannot move after the steel pipe is assembled. During the welding process, the welding position changes (horizontally, vertically, upward, and inward). Rotating the welding port means rotating the welding port during the welding process so that the welder can...
