A Taguchi- Single Response Approach to Optimize Bead Geometry in TIG Mild Steel Weld

Abstract

This study is aimed at applying the Taguchi single response
optimization tool to welding technology. These tools aid in the
selection of optimum process parameters, and optimum process
parameters are responsible for the improvement in the quality of weld
metal. The tool employed here is the Taguchi-single response concept.
This approach uses the signal to noise ratio, ANOVA table and a
confirmatory test method to determine the most economically desired
process parameters. In this study, the optimum process parameters
obtained is I2 V1 Wd2 GFR1 with a prediction error of 5.29dB. This
means that for the existing process parameter with 5.29Db.To
confirm the validity of the optimum process parameters, the estimated
average at the single state of the process parameters were found to be
within the predicted range of 95% confidence level. The additive law
equation was used to generate the predictive value that was used to
determine the performance of the process parameters.
