Abstract
In the present work, the influence of current pulsation on microstructural morphology and mechanical properties of micro-plasma arc welded of 0.7-mm thick Alloy 718 is investigated. The pulsation of current improves the solidification morphology as compared to continuous mode. The effect of peak current, duty cycle, and pulse frequency on cooling rate, weld morphology, and mechanical properties are reported herein. The calculated solidification...
