SAW is a unique welding method since it involves the arc which is completely submerged under the layer of granular flux. During welding, this flux that contains lime, SiO2, MnO, CaF2 and other compounds reacts with the contaminants in the molten weld metal and forms slag. Thus, slag is considered as waste materialsp.info US3472649A - Electric-arc steelmaking - Google PatentsUS3472649A US3472649DA US3472649A US 3472649 A US3472649 A US 3472649A US 3472649D A US3472649D A US 3472649DA US 3472649 A US3472649 A US 3472649A Authority US United States Prior art keywords furnace iron scrap bath percent Prior art date 1965-09-03 Legal status (The legal status is an assumption and is not a legal conclusion.sp.info Part XIII.
