Principle and characteristics of submerged arc welding process，Arc welding is a method in which the arc is welded under the flux layer. This method uses the heat generated by the arc burning under the flux layer between the welding wire and the weldment to melt the welding wire, flux and base metal to form a weld and connect the weldment. In submerged arc welding, granular flux protects and alloying the arc and welding area, while welding wire is used as filler metal.
