Abstract

This research describes the optimization of electric current of Spot TIG welding on the tensile strength of SPCG 250 mild steel using fuzzy Sugeno ANFIS type. By using ANFIS method, the error value is 11.8712. The validation process is carried out by matching the ANFIS output results and the real data with the mechanical properties of the material, namely 320 MPa, so that the optimization value of 80 A current and 10 holding time with a value of 342.92 MPa determine the optimization of the effect of electric current parameters on the results. Tensile strength test, decision making system can be done using the ANFIS method.
