  • PHMSA: Stakeholder Communications - Manufacturing Process

    The pipe seam is then welded by a single pass of an arc welder on the interior and exterior surfaces (hence double submerged). The welding arc is submerged under flux. The advantage of this process is that welds penetrate 100% of the pipe wall and produce a very strong bond of the pipe material.
