Mechanical Properties and Micrstructure of Al-5083 by TIG

The current study deals with the parametric and micro-structural analysis and of Al5083 welded specimen with an automated TIG set up. TIG provides one of the most precise and quality welding fastest welding speed can be used in marine, aerospace and ship industries. Welding speed, current, gas flow rate are the important parameters which are directly affecting the tensile strength of welded specimen and plays an important role in metallurgical changes. Wire EDM cutting is used to cut the welded specimen as per ASTM standard. Tensile strength increases by increasing welding speed till an optimum value and further decreases by increasing the welding speed. Micro-Structural changes are investigated by X-ray diffraction (XRD) and Scanning electron microscopy (SEM) and Energy dispersive spectroscopy (EDS). (c) 2017 Published by Elsevier Ltd.
