Sub-Arc Welding

Submerged arc welding (SAW) is a common arc welding process. The process requires a continuously fed consumable solid metal cored electrode wire.

The molten weld and the arc zone are protected from atmospheric contamination by being “submerged” under a blanket of granular fusible flux consisting of lime, silica, manganese oxide, calcium fluoride, and other compounds. QSM’s 1000Watt AC Lincoln Welding Power unit is on 3m High Boom with 3m Long reach.

With heavy duty rotators we can easily locate and weld Cylinders for all types of industries including Pully Shells for mining, and Pile Shells for Construction. With our in house rolling facility we can offer our clients one-stop-shop rolling and welding solution including removal or green, and re rolling after welding without expensive transport costs.

And to further value add to our clients we can also offer NDT to the welds using our inhouse NATA approved NDT Lab.
