Optimization Of Flux Constituents For Low Carbon Steel Plates Based On The Weld Bead Width With Taguchi Analysis By Submerged Arc Welding Process
Submerged arc welding flux system of SiO2-Al2O3-CaO based was designed to optimize the flux constituents
for weld bead width. Taguchi L9 orthogonal array was used to design the flux system. Three constituents of the flux were
varied, with their three levels such as NiO,MnO and MgO. Bead on plate arrangement was used. Nine experiments were
performed at open circuit voltage at 32 volt. Weld bead width was measured as a response for each experiment. Optimal
condition for flux constituents was studied by developing a regression model. Predicted values were compared with the
measured value of bead width. The results are within the optimal condition of analysis.
