Experimental Investigation Effect on Saw using Response Surface Methodology (RSM)

Submerged arc welding is preferable more its inherent qualities like easy control of variables, high quality, deep penetration, smooth finish. The quality of weld depends on the bead geometry of the weld which in turn depends on the process parameters. To automate a welding process, which is the present trend in fabrication industry, it is essential that mathematical models have to be developed to relate the process variables to the weld bead parameters. Selection of process parameters has great influence on the quality of a welded connection. Welding input parameters play a very significant role in determining the quality of a weld joint. In this present work, the effect of Response Surface Methodology approach for experimental investigation of submerged arc welding parameters Viz. Current, Voltage, Travel speed and Electrode diameter on weld bead geometry has been studied. Response surface methodology (RSM) technique is applied to determine and characterize the cause and effect relationship between true mean responses and input control variables influencing the responses.
