The purpose of this research is to assess the possibility of joining two different materials (aluminum and steel) by using one of the thermal joining that is gas metal arc welding (GMAW) which can be used in the industries such as in aviation and automotive. The joints will be obtained by GMAW process in which melts metal by heat supplying an electric arc established between a continuously fed filler wire electrode. Test will be conducted with constant welding parameter but with the different voltage. The results will be analyzed by means of hardness test, impact test, ultimate tensile test and microstructure at the welded joint. The strength of the joints varied with increasing of voltage when welding process is implied. The results will be proved after the tests are being done whether the technique of joining aluminum and steel by using GMAW is applicable.
