Aluminium and aluminium alloys have large uses in different industries due to its higher strength to weight ratio. Due to controllable heat input and filler consumption Tungsten Inert Gas Welding (TIG) is widely used in aluminium welding. In this work, bead geometry of Al 6060 alloy have been studied in different AC TIG welding parameters, like welding current, welding speed etc. Butt joint was performed. From the observation, it is found out that at a current 177, 190 and 200 A with a welding speed of 110, 130 and 150 mm/min respectively, good depth of penetration can be achieved, and hence, this condition can be used for joining aluminium alloy satisfactorily.

Aluminium and aluminium alloys have large uses in different industries due to its higher strength to weight ratio. Due to controllable heat input and filler consumption Tungsten Inert Gas Welding (TIG) is widely used in aluminium welding. In this work, bead geometry of Al 6060 alloy have been studied in different AC TIG welding parameters, like welding current, welding speed etc. Butt joint was performed. From the observation, it is found out that at a current 177, 190 and 200 A with a welding speed of 110, 130 and 150 mm/min respectively, good depth of penetration can be achieved, and hence, this condition can be used for joining aluminium alloy satisfactorily.
