  • Equipment for Submerged Arc Welding - TWI

    Equipment for submerged arc welding. The submerged-arc welding (SAW) process is similar to MIG where the arc is formed between a continuously-fed wire electrode and the workpiece, and the weld is formed by the arc melting the workpiece and the wire. However, in SAW a shielding gas is not required as the layer of flux generates the gases and ...
