Abstract

PURPOSE:Flux for submerged arc welding, being able to obtain sound joint stably by specifying the composition of indispensable component and also, specifying bulk density and hydrogen content. CONSTITUTION:Flux for submerged arc welding, containing SiO2; 29-40 wt.% MnO; 5-13%, CaO; 14-21%, MgO; 6-14%, Al2O3;7-15% and fluoride of alkali metal or alkali earth metal; 0.4-8%, as indispensable component and containing less than 0.005% of hydrogen against total weight of flux and also, having 1.41- 2.22 g/cm<3> of bulk density. By using the above flux, even on occasion of carrying out submerged arc welding using steel material having black skin or paint film on its surface, as normal welding wire as it is, defects, such as pock-mark, pit, blow hole, convex bead, under cut etc., are not produced on the joint zone and the sound joint zone is able to obtain stably.
