چکیده
The main objective of industries reveal with manufacturing better quality product at low cost and increase productivity. TIG welding is most vital and common operation use for joining of two similar or dissimilar parts with heating the material or applying the pressure by using the filler material for increasing productivity with less time and cost constrain. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. The purpose of this study is to propose a method to decide near optimal settings of the welding process parameters in TIG welding. The paper presents the influence of welding current, arc voltage, and gas flow rate on strength of SS-202 and mild steel material during welding. A Taguchi Orthogonal array, signal to noise (S/N) ratio and analysis of variance (ANOVA) are employed to investigate the welding characteristics of dissimilar joint and optimize the welding parameters.

The effect of activating fluxes on 316L stainless steel weld joint characteristic in TIG welding using the Taguchi method
Gas tungsten arc welding is fundamental in those industries where it is important to control the weld bead shape and its metallurgical characteristics. However, compared to the other arc welding process, the shallow penetration of the TIG welding restricts its ability to weld thick structures in a single pass (~ 2 mm for stainless steels), thus its productivity is relativity low. This is why th...
