Investigation of Strength of V & U Groove Butt Joint by TIG Welding & its Analysis
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
Now a days in shipping, aerospace and in process industry aluminium and its alloys are commonly used because of their valuable properties such as light weight, better corrosion resistance and weld ability. The current study aim is to Investigation of Strength of V & U Groove Butt Joint on mechanical properties of AA2025 and AA7025 for different groove angle and bevel heights keeping root opening, voltage and current constant. The specimens are prepared by using V and U groove butt weld joints. In this work gas Tungsten Inert Gas (TIG) welding process has been selected because TIG welding is the process of joining different materials with high quality in the presence of inert gas. Alternating current power source has been selected because of better cleaning action and due to alternating current the high heat concentration on the material can be avoided. Mechanical tests such as tensile test, impact test, hardness test have been conducted to find out the mechanical properties such as tensile strength, impact strength, toughness of HAZ.
