Effect of B2O3 Containing Fluxes on the Microstructure and Mechanical Properties in Submerged Arc Welded Mild Steel Plates

Effect of B2O3 Containing Fluxes on the Microstructure and Mechanical Properties in Submerged Arc Welded Mild Steel Plates

This paper represents a study on the effect of B2O3 additions in fluxes on the microstructure and mechanical properties of the weld metal formed during Submerged Arc Welding of Mild Steel plates. Five fluxes with about 2.5, 5, 7.5, 10 and 12.5% B2O3 were used with a low carbon electrode. Welding pro...
