The study of surface integrity on friction stir welded brass plates

Abstract

As brass materials are having high strength and high resistance towards corrosion, along with high thermal and electrical conductivity, these were the reasons for their wide usage in the industry as engineering materials. Although they have good appearance, they can also be shaped easily. Anyhow, fusion welding of brass is a difficult task, as during the process of fusion welding zinc evaporation has been a major concern which these alloys which affects its chemical and physical properties. Many researchers have been working for the new methods as problems due to fusion welding are not getting solved in case of brass. In this scenario Friction stir welding is one of the novel methods to solve these problems. Then, experimental investigations were needed in this domain. Although decent research works have been reported on FSW of Aluminum, copper and their alloys, but constrained work has been done in case of brass. This research aims to determine the optimum parameters for FSW of brass and corrosion test, tensile test, environmental tests, surface morphology and surface metallurgy results has been examined on the obtained weld joints.
