Abstract
Generally, the joining of parts in our industrial life is very important. The industries use joints to increase the length or surfaced area for their requirements and these requirements can be fulfilled generally by joints. Welding is one of the best methods of making joints in which the tungsten inert gas welding is an important method in the welding process. In welding, the beads are formed which are consisted of depth of penetration, weld width and reinforcement height. These dimensions of the beads are the deciding factors of mechanical properties of the weld. In this work, the several experiments were performed with tungsten inert gas welding machine to critically study the effect of welding speed on the dimensions of the bead. All the other input variables except the welding speed were fixed, as the feed rate at 2.12 mm/s, voltage at 9.0 V, welding current at 100 A for whole the experimentation period. Only the values of welding speed were varied and the effect of this variation on depth of penetration, weld width and reinforcement height was investigated. Total six pairs of mild steel plates of dimensions 75 mm × 50 mm × 5 mm were welded for six variations of welding speed. The results were tabulated and were expressed in three different diagrams in which one was for depth of penetration, one was for reinforcement height and one was for weld width. This study explains the sensitivity analysis of the effect of the welding speed on the three dimensions of the weld bead.
