It has been found that submerged arc weld-ing has a thermal efficiency of about 90 %, as against an approximate value of about 75 % for MMA welding. Submerged arc welding can be performed using either DC or AC. 1.2 Applications Submerged arc welding can be employed for an extremely wide range of workpieces.File Size: 2MBPage Count: 42sp.info How does the submerged arc welding process work?In the submerged arc welding process the flux-covered electrode is replaced by the granular flux and a bare electrode. An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux. This flux keeps the atmospheric contamination away. The process may be automatic or semi-automatic.See all results for this question
