    Difference between Double-sided Submerged Arc Welded Straight Seam Steel Pipe and Large Diameter Str

    Keywords: Difference between Double-sided Submerged Arc Welded Straight Seam Steel Pipe and Large Diameter Str

    Manual welding slag protection is widely used in double-sided submerged arc welding straight seam steel pipe and other large-diameter straight seam welded pipe manual welding, the last century, 40 years has been invented such a welding method. But the residue is not the electrode coating, special melting into the flux. The flux system is fed by a funnel filled with flux through a pipe to the front to be welded.


    The second difference is not using the electrode, the use of welding wire, because the wire can be continuously given; electrode, we burn a welding electrode must have a head to throw, and the operation was stopped, for welding and then welding.


    Double-sided submerged arc welding straight seam steel pipe uses, the first advantage is fully automated; the second advantage, it is under the submerged arc welding, so its heat exchange and protection performance is relatively strong, welding out The quality is relatively high; The third advantage, because the submerged arc welding in the arc buried in the bottom of the welding, so it can use high current, welding efficiency is relatively high, our country is being carried out recently West-East pipeline project.


    After the wire is changed, the wire is continuously fed to the welding wire by means of a wire feed device and a welding wire. This welding method is a continuous feeding wire which ignites the arc under the fusible granular flux coverage, And a part of the flux melts and evaporates to form a cavity, the arc is stable combustion inside the cavity, so it is called submerged arc welding. The arc is buried in the cavity.


    Pipeline is a high-strength steel, the pipeline inside the factory in the first  pre-made into a section, and then get to the site, in the field of welding, the pipeline is produced in the factory welding process is using submerged.
