Experimental Analysis of Friction Stir Welding of Dissimilar Alloys AA7075 and MG ZE42 Using Butt Joint Geometry
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 1
Abstract
The Aluminium alloy 7075 and Magnesium alloy ZE42 plates of 6 mm thickness are welded in the circular butt joint division by friction stir welding (FSW) process, utilizing vertical processing machine. Method parameters, for example, welding maximum speed and FSW rotational speed assume an essential part to acquire a superior weld joint for different metals/materials. The contact stir welding device is one of the basic parts to the achievement of this procedure. It comprises a tube shaped shoulder and a stick with various geometry. In the test work, the said apparatus has been outlined with a barrel shaped stick having four unique geometries for erosion mix welding of the disparate roundabout metal plates. Welding has been completed at welding speed changing from 10 to 40 mm/min and FSW rotational speed from 950 to 1500 rpm. Effects of progression parameters on butt welded circular joint were investigated for weld strength. In this research work, it is found that the welded joint between dissimilar metals alloys Al7075 and Mg ZE42 is framed utilizing FSW by choosing the appropriate device stick profile and welding parameters. It is recommended that friction welding of Aluminum composite and Magnesium compound with tapered butt joint geometry would be helpful later on for vehicle applications by getting the advantages from every material practically.
