Abstract

Dissimilar joints between copper and brass are performed using TIG/AC-ATIG/DC-ATIG. There is a reduction in mechanical strength of the weldment while TIG welding of copper and brass. To overcome these challenges, activated TIG (ATIG) welding has been used. Here, DC current straight polarity DCEN has been used for improved weld penetration through higher heat input to weldment for better strength. It is also inferred that the usage of Al2O3 with active flux in ATIG is not suitable because of inert behavior which in turn hinders the heat flow during the process. During DC current straight polarity DCEN welding results in reduced mechanical properties than the AC current welding due to the formation of coarse columnar grain structure observed in the weldment. AC-ATIG with SiO2 and TiO2 fluxes, the intermediate dendritic grain structures are observed in the weld zone.
