A review on effect of process parameters on weld features of copper and brass material in FSW and FSSW methods

Abstract

In this study, a literature survey has been done about similar and dissimilar copper and brass alloys joints by friction stir welding and friction stir spot welding methods. The effects of some important process parameters such as tool geometry, rotation speed and travel speed of tool on joint performances, change in weld microstructure, defect formation and occurrence of intermetallic compounds, which are adversely affect weld quality in dissimilar joint, have been summarized. The results of studies about joining of copper to copper, brass to brass, copper to brass, copper to aluminum or alloy, brass to aluminum or alloy, brass to steel have been reviewed in the present work.
