ABSTRACT:
A process for welding a rotatable machine component is provided which includes the steps of rotating the component about a longitudinal axis of rotation thereof; preheating an area of the component to be welded; depositing a plurality of weld beads in the area; post weld heat treating the area; and cooling the area to room temperature. During the entire process from preheating through cooling, the component is continuously rotated about its longitudinal axis.
