Submerged ARC WeldingEquipment

In Submerged Arc Welding a continuous solid wire, in the form of a spool is used as electrode. It is mechanically fed resulting in high deposition rates. The arc is submerged under a layer of dry granular flux. The higher feed enables the use of higher currents. This is one of the most economical processes for long joints and deep groove butt welds.
The equipment for SUB ARC consists of
A constant potential DC Power source.
Welding head (Boom or carrige mounting type)
Set of Accessories
Advantages of the process
Deep penetration
X ray quality welds
Uniform bead shape
Faster rate of welding
Higher deposition rates.
Application
Fabrication of penstock pipes, pressure vessels, LPG cylinders and other stuctural work.
