In the development of technology and industry, steel one important materials, evidenced by common use in world of manufacturing, maritime, building materials, piping, oil and gas. Therefore, important study and optimize the welding process parameters to improve the quality of the joints and minimize defects. This study aims to find various combinations MIG (Metal Inert Gas) process parameters for steel welding with variations in current strength and coolant. The method this study by conducting the MIG (Metal Inert Gas) welding process then conducting impact and fractography tests. The conclusion best magnetic particle test results is specimen 5 with impact price 0.609 Joule / mm2 and the worst result specimen 8 with impact price of 0.319 Joule / mm2 and the best impact fractography test results are specimen 6 obtaining impact fractography angle of 60.2 ° and the lowest result specimen 1 obtaining impact fractography angle of 60.2 °.
