    How to solve the deformation problem of spiral seam submerged arc welded steel pipe

    The spiral seam submerged arc welded steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tri-cone, the drill first produces elastic shear deformation of the stratum and then is removed under the pressure of the tri-cone. In the simulated environment, ...

    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...
