Why is DCEP used in submerged arc welding?
For single wire submerged arc welding, direct current electrode positive (DCEP) is used for most applications as it provides better control of bead shape, ease of arc initiation, and deeper penetration welds with greater resistance to porosity.See all results for this questionWhich is the best process for submerged arc welding?However, at very high welding currents, AC is preferred in order to minimize arc Submerged arc welding (SAW) process is a widely used weld- blow . Owing to the higher heat generation in this process, ing process in the industry for welding of thick plates, partic- high welding speeds up to 5 m/min are attainable.See all results for this questionWhich is the best DC source for arc welding?Introduction constant current DC source is used.
