    What should be paid attention to when welding galvanized steel pipe

    What should be paid attention to when welding galvanized steel pipe 1. The premise must be polished The galvanized layer of the weld must be polished away, otherwise air bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce the rigidity. 2. The welding c...

  • Precautions for welding stainless steel pipe fittings

    Precautions for welding stainless steel pipe fittings

    1. In order to prevent erosion due to heating, the welding should not be too long. It should be 20% less than the carbon steel electrode. The arc should not be too long. The layers should be cool quickly. The narrow weld bead is suitable. 2. The hardening of the stainless steel pipe fittings is q...

  • Stainless steel does not rust

    Stainless steel does not rust

    Stainless steel is an extremely thin, strong, dense, and stable chromium-rich oxide film (protective film) formed on its surface to prevent the relay of oxygen atoms. Continue to penetrate, continue to oxidize, and obtain the ability to resist rust. Once for some reason, this kind of film has bee...
