    The research conducted that is in laboratory using factorial Completely Random Design (CRD) Design Of Experiment. Researcher want to see the influence of independent variables on the dependent variable is whether the types of cooling (X1), types of groove welding (X2) and welding currents (X3) affect to distortion of welding (Y). The significant data, indicated by the normal plot that a significant factor affecting the response is a factor A, C, AC, BC and ABC. Where is the factor A is a types of cooling factor C is welding currents, factor AC is combination factor types of cooling and welding currents, factor BC is combination factor types of groove welding and welding currents, and ABC is combination factor types of cooling, types of groove welding and welding currents. Known from the regression model obtained value of RSquare is 75.99%, which is mean of factor A, C, AC, BC and ABC may explain the variable (Y) the distortion of welding 75.99%. the rest of 24.01% is explain by other factors, from the factors that could explain the variable Y for 75.99%. Keyword: Welding, Design of experiment, factorial CRD (Completely Random Design ).
