Ca0-Al203 based flux system along with other constituents like MGO. TiO,, MnO and CaF have been designed with the help of binary and ternary phase diagrams. The flux constituents selection has been made according to the flux liquidus temperature. Fluxes were prepared by agglomeration technique and basicity index (B.l.) varied between 1.20 and 3.8.

The influence of flux basicity on the transfer of carbon and distribution of silicon and manganese between weld metal and slag system has been determined. With the help of above data, a relationship has been developed between the flux composition and the gain or loss of these elements during welding. The results show that the flux composition which affects the physico-chemical and metallurgical characteristics of the slag, plays significant role in the transfer of C. Si and Mn to the weld metal.

Abstract


Ca0-Al203 based flux system along with other constituents like MGO. TiO,, MnO and CaF have been designed with the help of binary and ternary phase diagrams. The flux constituents selection has been made according to the flux liquidus temperature. Fluxes were prepared by agglomeration technique and basicity index (B.l.) varied between 1.20 and 3.8.

The influence of flux basicity on the transfer of carbon and distribution of silicon and manganese between weld metal and slag system has been determined. With the help of above data, a relationship has been developed between the flux composition and the gain or loss of these elements during welding. The results show that the flux composition which affects the physico-chemical and metallurgical characteristics of the slag, plays significant role in the transfer of C. Si and Mn to the weld metal.
