    Backing welding methods of argon arc welding stainless steel pipes
    The welding of stainless steel pipes typically involves three stages: root (backing) welding, fill welding, and cap welding. Among these, backing welding is the most critical step, as it directly influences both weld quality and construction progress. Currently, two primary backing welding approaches are used: argon-protected root welding and non-argon root welding. Each includes various sub-methods with distinct technical characteristics and field suitability. This article will briefly introduce backing welding methods of argon arc welding stainless steel pipes.

    Advantages and disadvantages of galvanized ERW pipe
    Galvanized ERW (Electric Resistance Welded) pipe is a high-frequency straight seam welded steel pipe that has been coated with a protective zinc layer through a galvanizing process. This zinc coating forms a dense barrier on the surface of the pipe, effectively isolating it from air and moisture. As a result, galvanized ERW pipes exhibit significantly enhanced corrosion resistance and a service life several times longer than that of standard ERW pipes. This article will briefly introduce advantages and disadvantages of galvanized ERW pipe.
