After spiral pipe forming and continues tack welding in spiral pipe mill, the pipe is transferred to Submerged Arc Welding (SAW) Station, where the tack-welded pipe seam is permanently welded using the multi-wire submerged-arc welding process.

This Submerges Arc Welding Station has been developed by Byard Spiral Mill Sdn. Bhd., with the implementation of modern process technologies such as Laser Seam Tracking system.  

For offline spiral production speed, three sets of offline sub-merge arc welding station are required to service the Off Line Spiral Mill to reach a production of 200,000ton/yr (Subject to the perimeter of pipes sizes).
