摘要：
Development of microstructure in the weld pool as well as in the partially molten zone is influenced by weld geometry and cooling of the weld metal besides heat input. Evolution of refined microstructure has definite advantage in AA2219 weldment to restrict the crack path. In the present paper, mechanisms of microstructure development in single pass and multipass gas tungsten arc welding of Al-alloy AA2219 alloy have been studied. Role of backing bar material and weld configuration in development of morphology and growth of microstructure have been discussed.
