Spiral Arc Welding

We offer spiral arc welding, also known as submerged arc welding. In this welding process, the material is submerged under a bed of fusible flex, which becomes conductive when heated. The resulting weld is sound, uniform and corrosion resistant, with a deep weld penetration. It is a high-speed, automated process that is used for long straight welds and is effective for thin sheets of metal. Submerged arc welding is used for pipes, tanks, vessels and enclosures. It is used for carbon steel, stainless steel, Hastalloy®, Inconel® and nickel alloys.
