Abstract
This research explains about the optimization of electric current TIG spot welding on the tensile strength of SPCG 250 mild steel using a fuzzy logic system. In this study using 2 types of fuzzy, namely Mamdani FIS and Sugeno ANFIS. By combining these 2 fuzzy types, the error value is 11.8712. In addition, regression analysis was also carried out on the input variable parameters of the output variable. From the results of the regression analysis, it is known that the parameters that influence it are electric current and holding time. The validation process is carried out by matching the results of fuzzy output, ANFIS output and real data to the mechanical properties of the materials which is 320 MPa, so the optimization value at current 80 A and holding time 10 with a value of 342.92 MPa is obtained. To the tensile strength test results, a decision-making system with fuzzy logic can be used using the ANFIS method.
