AOS produced pipe using a manual or automatic single sided SMAW process in 1927. The weld metal was deposited in a wide U-shaped groove. Prior to welding, the pipe edges at the groove were pressed together so as to cause the lower part of the groove to deform toward the pipe interior into a recess in a backing bar to contain the weld root.
Pipes For Drainage - Zhangzhou Steel PipesThe spiral submerged arc welded pipes (SSAW) are now adding significant momentum to global growth. SSAW steel pipes (Spiral Submerged Arc Welded Pipes) are made of hot-rolled coiled steel using a double-sided submerged arc welding method.
Spiral Submerged Arc Welded or SSAW pipes are highly noticeable because of their helical welding seam. Spiral steel pipe casing, which is also called pipe piles and bored pipe casing, is normally used in the foundation of structures that have soft soil. These pipes can also be used in water lines that require big diameter and lengths.
SPIRAL SAW PIPES - Mukat PipesHelical Submerged Arc Welded Pipes or commonly called Spiral Pipes are made from hot rolled coils. The Spiral Pipe forming Mill. The Pipe Mill decoils the strip, straightens it, prepares the edges for welding and feeds it into forming station to form the coil into pipe

Spiral Steel Pipe Submerged Arc Welding Process and Spiral Spiral steel pipe submerged arc welding process. 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.

Spiral pipe welding automation drives productivitySpiral pipe fabricators use multitorch submerged arc welding (SAW), which provides high deposition rates, accommodates thick pipe walls, and produces high-quality welds. This is welding-intensive work, and fabricators need high quality and speed to compete. Automation has helped provide both.
Spiral submerged arc welding, SAW pipe manufacturer, SAW Spiral submerged arc welding process performance:(1) raw materials that strip, wire, flux. Must go through rigorous testing before being put into the physical and chemical. (2) strip head and tail docking, using single or double wire submerged arc welding, in rolled steel by automatic submerged arc welding. (3) Before molding, the strip after flattening, cutting, trimming, planing, surface cleaning and
