Abstract
The lean manufacturing concepts and tools are presented as a good alternative to increase production efficiency, promoting cost reduction and increasing the quality of manufactured products. Tungsten inert gas (TIG) welding is a kind of metal joining processes that has found widespread usage across the industries; it involves the employment of a non-consumable conductive tungsten electrode in a shield of inert gas. A204GRB alloy steel and UNS 317 stainless steel have been used extensively in high pressure vessel fabrication and in similar applications, owing to their great strength and corrosive resistiveness. Further, the quality of the weldments is sturdily depending upon the input process variables, and finding their optimum combination is quite important. In the present investigation, the optimized quantities of the TIG welding variables namely, current, voltage level and the weld speed were identified with the aid of the Taguchi’s method for the dissimilar weld joints created with the aforementioned materials.
