In SAW, Process parameter and composition of welding flux plays a crucial role by influencing the mechanical and metallurgical properties of the weld bead to determine the quality of weld. The main objective of present work is to optimize the parameters effecting the weld. Generally “sio2-al2o3-cao” flux system is used in SAW process. In this work with a target to improve the efficiency of the weld and to attain better mechanical properties. Nickel oxide (Nio) and chromium oxide (Cro) powders are used in the flux by mixing in three different proportions and various experiments are conducted. Taguchi technique is used for design of experiments. Optimization of parameter is done using the analysis (ANOVA), regression models are developed using Minitab.
