In particular, its use in the form of plates is interesting due to its low weight and good mechanical and chemical resistance. Welding is a fundamental manufacturing process applied to Corten steel, but it can cause major changes in the chemical composition of the welded joint, changes in the microstructure and mechanical distortions due to the intrinsic characteristics of the process. In view of the above, the present work sought to find the best welding parameter for 2 mm thick Corten steel sheets and subsequently evaluate what changes occur in the characteristics of the welded joint when operating with the E 6013, E 7018 and E 7018 - W1 electrodes . The welding process was carried out with electrodes E 6013, E 7018 and E 7018 - W1. The samples were prepared for the butt weld test, the test was carried out by varying the operating current and then varying the root opening. From each tested bead, three samples were taken and prepared for the hardness test and subsequently the evaluation of the weld bead microstructure was carried out. The results found indicate that the best welding parameter for the 2 mm thick plate is 55 A and 0.75 mm of root opening, for the electrodes E 7018 and E7018 - W1. Operation with the E 6013 electrode resulted in many spatter and arc arc instability. There was a trend that the increase in current implies an increase in the hardness of the weld bead, and were found as main microstructures Acicular ferrite and polygonal ferrite.porAcesso AbertoAço cortenPatinávelMicroestruturaSoldagemCorten steelPatinable steelMicrostructureWeldingTCC
