Spiral Steel Pipe Submerged Arc Welding Process and Spiral steel rolled pipe wellhead Submerged arc welding

Mar 25, 2015 · Automatic submerged arc welding was invented in 1940, a new kind of welding method, it adopts slag protection as manual welding, but is not coated electrode, the slag is specially welding flux smelting. This coating system is composed of a funnel with welding flux through a pipeline to the front of the welding. The second difference is it uses welding wire instead of the electrode because welding SSAW Steel Pipe, SAWL Steel Pipe - Seamless Steel PipeSSAW steel pipe (spiral submerged arc welded steel pipe) is formed by spiral bending of hot-rolled strip steel, and spiral seam steel pipe (also called spiral welded pipe, spiral pipe spiral steel pipe) is formed by automatic welding of submerged arc for inner and outer joints.
