What is Submerged Arc Welding?
Submerged Arc Welding (SAW) is a process where the weld and arc zone are submerged beneath a blanket of flux. The flux material becomes conductive when it is molten, creating a path for the current to pass between the electrode and the workpiece. It also generates a protective gas shield and a slag, which protects the weld zone. The primary advantages of submerged arc welding are efficiency and quality. When large amounts of filler material are required, the sub arc process provides high deposition rates with deep weld penetration.
We offer AC and/or DC power sources ranging from 400 amp to 1,500 amp. We have single and tandem sub-arc welding heads, wire feeders, control systems, flux management systems and weld monitoring cameras along with sub-arc tractors and weld positioning equipment. Our submerged arc power sources feature the latest in digital process control technology for increased weld speeds, higher quality welds and improved efficiencies in a single or multi-arc environment.

Submerged Arc Welders
Red-D-Arc offers semiautomatic and automatic submerged arc welders for sale, lease and rent. We offer AC and/or DC power sources ranging from 400 amp to 1500 amp.
Available submerged arc power sources feature the latest in digital process control technology for increased weld speeds, consistently higher quality welds and improved efficiencies in a single or multi-arc environment.
Submerged Arc Welding Heads and Controls
Single and tandem (multi-wire and multi-arc) submerged arc welding heads are available for sale, lease and rent. Tandem systems include multi-arc heads with up to 6 welding arcs and multi-wire heads capable of up to 4 wires, all of which are available to accommodate deep groove and narrow gap applications. We have extensive experience designing special purpose, custom welding heads to suit any requirement.
Red-D-Arc’s tandem welding system provides a touch screen interface for data monitoring and provides full welding control. The multi-arc central console system provides control of up to 6 weld heads and allows welding parameters to be saved and downloaded. An ergonomic hand held pendant allows the operator flexibility to observe the weld and adjust parameters "on the fly".
Available wire feeders/controllers include the NA3S, NA4 and NA5R automatic wire feeders.
