Sub Arc Insights

What is Sub Arc?

Submerged arc welding (SAW) is a welding process where the arc and weld zone are shielded by a granular flux. The arc is submerged under the flux, making it invisible and producing virtually no sparks, spatter, or fumes. It is commonly used for high-deposition rate welding of thick materials, especially in structural steel fabrication, shipbuilding, and pressure vessel manufacturing.

Flux Core

Flux core arc welding (FCAW) is an arc welding process that produces coalescence of metals by heating them with an arc between a continuously fed consumable flux-cored electrode and the workpiece. It offers an alternative method for welding, although it is not as widely used for very thick materials that sub arc welding may be suited to.

Stick

Shielded metal arc welding (SMAW), also known as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. It is often used in similar applications as Sub Arc, providing competition in some scenarios.
