How Submerged Arc Welding Can Improve Productivity

Submerged arc welding is a wire-fed process that uses a granular flux to shield the arc from the atmosphere. As the name suggests, the arc itself is buried in the flux, meaning the arc is not visible when parameters are correctly set with a sufficient layer of flux. The wire is fed through a torch that moves along the weld joint, and SAW can be

Submerged Arc Welding : Working Principle, Functionality

Apr 22, 2020· 1). Why is submerged arc welding referred to as submerged? SAW got its name as submerged because the welding joint and arc are submerged underneath a layer of flux. 2). What is the main purpose of submerged arc flux? The flux is used for welding a kind of small insulative material that is composed of multiple small particles. 3).
