The present research has been done to investigate the influence of different input process parameters on the desired response (flux consumption) in the submerged arc welding process. Fractional factorial technique has been used to design the experiment to reduce the number of runs. The effects of welding current, arc voltage, travel speed and nozzle to plate distance have been found on the flux consumption. The Design Expert software has been used to obtain relationship between the response and parameters. The effect of all the input parameters on the output responses have been analyzed using the analysis of variance (ANOVA) and mathematical modelling.
