Modelling and Process Optimization for Tig Welding Based On Taguchi Method and Simulated Annealing Technique

Abstract

In the present study, emphasis has been given to perceive the effect of some decided on enter
parameters at the great of butt-welded joints, even as welding of chrome steel with the aid of
tungsten inert gas (TIG) welding. Experiments had been carried out as consistent with L9
orthogonal array of Taguchi method. The enter parameters considered in the take a look at
are: cutting-edge, gasolines go with the flow fee and arc gap. Statistical strategies analysis of
variance (ANOVA), signal-to-noise (S/N) ratio and major impact plots have been used to
study the results of welding parameters on remaining tensile energy of weld specimen.
Simulated annealing has been used to optimize the welding parameter to maximize last
tensile energy of weld specimen. From the effects of this study, gasoline flow rate is
recognized because the maximum influential welding parameter on final tensile strength.
Confirmatory test has been conducted to validate the predicted setting.
