Abstract
The current study aims to investigate the effects of input factors on UTS (ultimate tensile strength), PE (percentage elongation), bead width and depth of penetration in TIG welding austenitic stainless steel 304L. Experiments were systematically designed using the Taguchi L9 orthogonal array technique, allowing efficient exploration of the parameter space using only nine experimental runs. X-rays radiography test was taken of the weld specimens to look for outer and inner surface defects. This study emphasizes the use of and TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method to find the ideal input parameters as well as significant outcome. Engineers and technicians may identify parametric parameters for better welding with the use of recent research and thorough study on connecting incompatible on those materials.
本研究旨在探讨输入因素对304L奥氏体不锈钢TIG焊接中UTS（极限抗拉强度）、PE（伸长率）、焊头宽度和焊深的影响。实验采用田口L9正交阵列技术进行系统设计，仅用9次实验就可以有效地探索参数空间。对焊缝试样进行了x射线检测，以寻找外表面和内表面的缺陷。本研究强调使用TOPSIS （technical for Order of Preference by Similarity to Ideal Solution）方法来寻找理想的输入参数和显著的结果。工程师和技术人员可以利用最近的研究和对这些材料的不相容连接的深入研究来确定参数参数，以便更好地焊接。
