Abstract : The current work investigates effect of different oxide fluxes (TiO2, Cr2O3, CuO, and MoO3)on single pass
autogenous tungsten inert gas welding of P91 steel. Weld bead geometries obtained with and without use of fluxes were
studied. All the oxide fluxes resulted in improvement in depth of penetration and reduction in bead width. The role of
oxygen content was analyzed and it was found that 30-80 ppm oxygen content is favorable for improving depth of
penetration. Additionally, metallographic studies were done with the help of scanning electron microscopy.
