Submerged Arc Welding - Miller - Welding Equipment
Submerged Arc Welding Principles Submerged Arc Welding (SAW) uses heat generated by an arc formed when an electric current passes between a welding wire and the workpiece. The tip of the welding wire, the arc, and the weld joint are covered by a layer of granular flux. The heat gen-erated by the arc melts the wire, the base metal and the flux.The ABCs of Arc Welding and Inspection - KOBELCOwelding consumables. 1.2.2 Submerged arc welding The submerged arc welding (SAW) process was invented in 1935. This is very process efficient because canit use high currents from 500 to 1300 amperes, thereby obtaining deeper weld penetration into the base metal. This process, therefore, is suitable for welding thick-section steel materials.US3328212A - Submerged-arc welding composition - US3328212A US468114A US46811465A US3328212A US 3328212 A US3328212 A US 3328212A US 468114 A US468114 A US 468114A US 46811465 A US46811465 A US 46811465A US 3328212 A US3328212 A US 3328212A Authority US United States Prior art keywords percent welding composition submerged granular Prior art date 1965-06-29 Legal status (The legal status is an Cited by: 17Publish Year: 1965Author: Thomas L Coless
