Product Description
Hot dipped GI Tube Galvanized Steel Pipe
Galvanized steel pipes are usually coated with zinc on the outside of low carbon steel. The galvanized layer is usually 20 um thick. The melting point of zinc is 419 C and the boiling point is about 908 C. In welding, zinc melts into liquid and floats on the surface of the molten pool or at the root of the weld. Zinc has a high solid solubility in iron. Zinc liquid will etch weld metal along grain boundary. Low melting point zinc will form "liquid metal embrittlement". At the same time, zinc and iron can form intermetallic brittle compounds. These brittle phases reduce the plasticity of weld metal and cause cracks under tensile stress. If fillet welds, especially T-joints, are most prone to penetrating cracks.
