Abstract
This study is aimed at optimizing the input process parameters required to obtain the appropriate mild steel bead height. Further investigations from the study of other researchers, stated that the criteria for assessing the bead height is that the lower the height of the weld bead, the better the quality of the weldment. Therefore, the smaller the better criteria of the Taguchi method was applied. The signal to noise ratio obtained were used to determine the optimal input process parameters. The optimum process parameters determined was arranged in a coded form, which A1, B2, C, D,
The Analysis of Variance (ANOVA) was conducted to evaluate the level of contribution each input of the weldment. A confirmation test was carried, and from the test, it was found that there was an improvement in the quality of the weldment made by using the optimum parameters over the existing parameters.
