The Effect of Copper and Brass on Friction Stir Welded Dissimilar Aluminium Alloy When Used in Thin Sheet Form
IJRE Publisher, 2016Co-Authors: Krishna G. Gopala, Reddy P. Ram, Hussain M. ManzoorAbstract:In recent year’s aluminium and aluminium alloys are most widely used in many applications because of light weight, good formability and malleability, corrosion resistance, moderate strength and low cost. Friction Stir Welding (FSW) process is an efficient and cost-effective method for Welding aluminium and aluminium alloys. FSW is a solid-state Welding process that means the material is not melted during the process. Complete Welding process accomplishes below the melting point of materials so it overcomes many Welding defects that usually happens with conventional Fusion Welding Technique which was initially used for low melting materials. Though this process is initially developed for low melting materials but now the process is widely used for a variety of other materials including titanium, steel and also for composites. The present butt jointed FSW experimental work has been done in two ways. Initially, a comparison of tensile properties of friction stir (FS) welded similar aluminium alloy (AA6351 with AA6351) and dissimilar aluminium alloy (AA6351 with AA5083) combinations. Later the effect of impurities (copper and brass) in sheet form (0.1 mm thick) when used as an insert in between two dissimilar aluminium (AA6351 with AA5083) alloy plates during FSW. Tensile tests were performed for these combinations and results were compared for with and without using strip material (copper and brass)

advances in Fusion Welding Technique of austenitic stainless steels
Key Engineering Materials, 2011Co-Authors: Kuanghung Tseng, Hsiang Lin SungAbstract:Activated flux assisted tungsten inert gas (TIG) Welding of austenitic 316L stainless steel was investigated. Autogenous TIG Welding was used to produce a bead-on-plate weld. The FeO, FeS, and FeF2 were selected as the flux powders. The results showed that the FeS and FeO fluxes produced high aspect ratio welds, while the FeF2 flux produced a relatively low aspect ratio weld. The undercut defect was produced with use of the FeS flux. An experimental result suggested the constriction of arc column as a mechanism in improving activated TIG penetration. In addition, activated TIG process can increase the delta-ferrite content in austenitic stainless steel weld metal.
