Tungsten Inert Gas Welding process was utilized to analyze the effect of input welding process parameters on depth of penetration of the weld. The important input welding process parameters used were selected as voltage, current, speed of welding and the feed rate. The plates of low carbon steel AISI 1010 having dimensions of 75 mm × 50 mm × 5 mm were used to obtain the weld. Total 16 pairs of plates were required to be welded to have 16 welds using tungsten inert gas welding process. Voltage, current, feed and speed of welding were considered as input welding process parameters and the depth of penetration was selected as output parameter. The sensitivity analysis was done by having three input welding process parameters at constant values and changing only one parameter. In this way the effect of welding, current, voltage, speed of welding and feed rate were investigated and the corresponding values of depth of penetration were recorded in table number 1 and sensitivity analysis for every input process parameters were shown with the help of Figs. 1, 2, 3, and 4. Generally the depth of penetration increased with increase of current but decreased with voltage, feed rate and welding speed in the present work.
