Double Submerged arc welded pipe, DSAW pipe - Sunny Steel

Double Submerged arc welded pipe, DSAW pipe. Then the edges of the rolled plate are formed so that V-shaped grooves are formed on the interior and exterior surfaces at the location of the seam. The pipe seam would then be welded by a single pass of an arc welder on the interior and exterior surfaces. The welding arc is submerged under flux.

What is The Differences Between LSAW Pipe and SSAW Pipe

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.

(SAW) Submerged Arc Welding Welding and NDT

Jan 29, 2019 · Submerged Arc Welding (SAW) is an arc welding process in which arc is generated between a bare electrode and the workpiece. The arc and the molten weld pool are submerged in a blanket of granular fusible flux on the workpiece. Flux covers the arc and prevents fumes, sparks, spatter, and intense ultra violet radiation from escaping, which makes this process very different from other arc welding ...

Submerged Arc Welding (SAW) Equipment and Applications

Submerged arc welding requires more thorough edge preparation and better fit-up than shielded metal arc welding. This is because in SAW a large molten metal pool is formed so if the fit-up is poor, the molten metal and slag may run out through gaps, thus affecting the weld quality.

Submerged arc welding - Wikipedia

Submerged arc welding. The first patent on the submerged-arc welding (SAW) process was taken out in 1935 and covered an electric arc beneath a bed of granulated flux. Originally developed and patented by Jones, Kennedy and Rothermund, the process requires a continuously fed consumable solid or tubular (metal cored) electrode.
