چکیده مقاله
In this study, the effect of rotating arc on the microstructure and mechanical properties of the fusion zone in manual metal arc welding was investigated In order to generate a rotating arc, the welding electrode was rotated at a constant speed 180 rpm during the SMAW process using a direct current DC motor to enhance molten pool mixing Welding operations were performed using E10 UM 60R electrode To investigate the microstructure, the samples were subjected to metallographic examinations Further, the hardness values distribution was evaluated in the fusion zone The results indicate that the application of a rotating arc leads to changes in the microstructural morphology of the fusion zone The Vickers hardness test showed that using rotating arc at both flow levels leads to a significant increase in hardness of up to 120 Vickers and it's more uniform distribution in fusion zone relative to conventional arc mode
