OPTIMIZATION OF PERFORMANCE OF ARC WELDING USING FLUXES IN WELDED SHIP STRUCTURES FROM HY-100 AND HY-130 KPSI

The following report summarizes the progress made in the production of experimental high purity submerged arc fluxes for the welding of HY-130 Steels. The initial studies focused on the effects of flux basicity or acidity on weld metal oxygen content. This study indicates that oxygen levels in submerged arc weld metal are substantially reduced when very basic fluxes in the MgO-Al2O3-SiO2 system are used. The mechanical properties of the weldments produced with the very basic fluxes were not greatly improved. However, this trend may be attributed to a weld metal silicon content which exceeded 0.40%.
