REVIEW OF TIG WELDING PAREMETER ON STRENGTH BASIS
Amitabh Kumar Soni, S.P. Shrivas
ABSTRACT
The current study deals with the parametric and microstructural analysis and of AA5052 and AA6061 welded specimen with a TIG (Tungsten Inert Gas) set up. TIG provides one of the most precise and quality welding fastest welding speed can be used in marine, aerospace and ship industries. Current, gas flow rate and distance between electrode and workpiece are the important parameters which are directly affecting the tensile strength of welded specimen and play 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 current till an optimum value. Micro-Structural changes are investigated Scanning electron microscopy (SEM) and Optical microscope.
