Spiral welding process is totally different with straight welding. A continuous full penetration metal inert gas weld overlay is used to rebuild or repair damage from wear, erosion, corrosion or cracking, or to enlarge the dimensions of a component on a mating part during spiral welding process.
SSAW Spiral Welded Steel Pipe stands for Spiral submerged arc welding. Its forward direction and forming pipe centerline hose reel molding angle which could be adjusted according to clients special requirements, side molding edge welding and weld them into a spiral line.
