Abstract
A process of welding a superalloy is provided. The process includes applying a first amount of energy to a substrate comprised of the superalloy to form a melt pool along a length of the substrate and in a weld direction. The process also comprises advancing the melt pool in the weld direction along the length via the first amount of energy, the melt pool having a width transverse to the weld direction. Further, the process includes applying a second amount of energy to the substrate that extends outside the width of the melt pool at a trailing edge of the melt pool, which second amount of energy causes, relative to a process without application of the second amount of energy: broadening of the width of the melt pool at the trailing edge of the melt pool as the melt pool advances in the weld direction; and reducing segregation of artifacts and stress concentration along a centerline of the width.
