Spiral Welded Pipe Process

The welding of the spirally welded pipes is based on the Double-Sided Submerged Arc Welding (DSAW) process.

DSAW’s better penetration makes it possible to achieve higher weld travel speeds without impairing quality, thus improving productivity and lowering costs.

The first welding pass is done by using a DC arc, to achieve a large and concentrated penetration. The second pass is done by using an AC arc, to achieve better deposition rates.

The result of the multi arc welding on both sides of the coil is a full penetration weld of a very high quality produced in a cost effective way.

Spiral Welded Pipe can be used for Fluid pipe, Power Plant, Structure pipe, High and low pressure Boiler tube, Conduit pipe, etc..
