The ST 37 Steel ordinarily has good tensile strength, hence, the purpose is generally used for the building frame. An electric arc welding is one of the welding methods of joining the metal by means of an electric arc flame which is directed to the metal surface to be joined. The research conducted using factorial Completely Randomized Design (CRD) in the Design Of Experimental method. The aim of this observation is to investigate the influence of independent variables on the dependent variable, whether the types of cooling (X1), types of groove welding (X2) and welding currents (X3) affect to distortion of welding (Y) on the st 37 steel joints. The significant data are indicated by the normal plot distribution in which the significant factors (A, C, AC, BC, and ABC) influenced the response. The A factor is the type of cooling, C factor is welding currents, AC factor is a combination of cooling types and welding currents, BC factor is combination factor between types of groove welding and welding currents, and ABC factor is combination factor of cooling types, groove welding types and welding currents. Based on the regression model reached the value of RSquare is 75.99%, which means the A, C, AC, BC, and ABC factor represent the influence on the distortion of welding at that value. While the rest of 24.01% is described by other factors
