What kind of current is used in submerged arc welding?


What kind of current is used in submerged arc welding?

The submerged arc welding process uses either direct or alternating current, but the direct current is used for most of the applications. Both direct current electrode positive (DCEP) and direct current electrode negative (DCEN) are used. The constant voltage with the direct current power is popular for SAW with 3.2 mm and small diameter wire.See all results for this questionsp.info Which is the best material for a marine water heater?Stainless is the best material to combat the harsh corrosive environment.
