Optimization of Flux for Bead Geometry and Weld Dilution in SAW Using Gray Analysis

This study has been conducted to find out and optimal composition of flux for low width, reinforcement, dilution, and high penetration of the weld. The weld geometry decides the load-carrying capacity of the weld, and dilution effects describe the elements transfer to the welds. Both of these factors affect the load-bearing capacity of the welded material. The fluxes were designed using RSM and were made by agglomeration technique. The optimized flux contains CaF2, FeMn, and NiO each as 8, 2, and 2%.
