Automated TIG Welding System, Micro hardness Test, Tensile TestAbstract
To advance the welding quality of Aluminium alloy plate an automated TIG welding arrangement has been developed, by which welding speed can be controller during welding procedure. Welding of Al alloy plate has been attained in two phases. During 1st model of welding, one side welding is done over Aluminium alloy plate and during 2nd phase both sides that is two sides welding is done for the aluminium alloy, by changing the welding parameters. Effect of the welding speed & current on tensile strength of the welded joint will be investigated for both weld types of joints. Here optical microscopic analysis is carried out on the weld zones to obtain the effect of welding parameters on welding quality. Even micro-hardness is also calculated at the cross section to understand the change of mechanical properties at the welded zones.
