Ramakant Sharma June 7 2020. Submerged arc welding (SAW) is a welding process where the tubular electrode is fed continuously to join two metals by generating heat between electrode and metal. The area of the arc and molten zone gets its protection from the atmospheric contamination by submerging under a blanket of granular flux.
