  • Characteristics of construction method of argon arc welding of thin-walled stainless steel pipe socket

    Characteristics of construction method of argon arc welding of thin-walled stainless steel pipe socket

    1. The welding process does not require welding materials (replaced by the pipe expansion side). The steel pipe is inserted into the socket of the pipe fitting, and the end of the bearing is welded in a circle with tungsten argon arc welding (GTAW) to melt the pipe into one body. The welding seam...

  • Four methods of measuring the length of spiral steel pipe

    Four methods of measuring the length of spiral steel pipe

    1. Improved encoder length measurement This method is an indirect measurement method. The length of the steel pipe is measured indirectly by measuring the distance between the two end faces of the steel pipe and their respective reference points. Set a length measuring trolley at each end of the ...
