    Abstract: A method of modifying an article includes welding a plurality of weld rows of weld beads on a surface of the article such that a gap is formed between each pair of neighboring weld rows. The method optionally includes welding a plurality of fill rows of fill beads on the surface of the article such that each fill row of the plurality of fill rows fills at least a portion of one of the gaps. The weld rows and the fill rows increase a thickness of the article at the surface, provide an uneven contour of the article, and operate as turbulators on the surface of the article. A component includes an article having a surface and a plurality of weld rows of weld beads on the surface of the article arranged such that a gap is formed between each pair of neighboring weld rows.

    Abstract: A fabricated article includes a substrate and one or more turbulators formed on the substrate. Each of the one or more turbulators includes at least one root portion providing a concave transition between the substrate and the turbulator. In some embodiments, the fabricated article is formed by a turbulator fabrication process. The turbulator fabrication process includes concurrently directing the first fusion energy toward a first side of the turbulator material extending from the substrate and the second fusion energy toward a second side of the turbulator material opposite the first side and extending from the substrate. The directing of the first fusion energy and the second fusion energy shapes the first side of the turbulator material to have a first contour and the second side of the turbulator material to have a second contour, thereby forming the one or more turbulators on the substrate.
