Abstract: A gas turbine component can be refurbished and/or repaired with an arc welding process that is used in conjunction with a 6-axis robot, a camera and a robot controller/vision processor. Applied to a wire fed plasma welding process, the vision system identifies the part, constructs a weld path based on the part's individual contour, and calculates a trajectory (with or without sinusoidal oscillation) for the robot arm to follow.

Abstract: A weld process cuitable for repairing precipitation-strengthened superalloys, and particularly gamma prime-strengthened nickel-based superalloys. The process entails forming a weldment in a cavity present in a surface of an article formed of a precipitation-strengthened superalloy. The cavity has a root region and a cap region between the root region and the surface of the article. A solid body formed of a superalloy composition is placed in the root region of the cavity so as to occupy a first portion but not a second portion of the root region. A first filler material formed of a solid solution-strengthened superalloy is then weld-deposited in the second portion of the root region. Subsequently, a second filler material formed of a precipitation-strengthened superalloy is weld-deposited in the cap region of the cavity.

Abstract translation: 可用于修复沉淀强化超级合金，特别是γ初始强化的镍基超级合金的焊接工艺。 该方法需要在存在于由沉淀强化的超级合金形成的制品的表面中的空腔中形成焊件。 空腔具有在根部区域和物品表面之间的根部区域和帽区域。 由超合金组合物形成的固体被放置在空腔的根部区域中，以便占据根部区域的第一部分而不是第二部分。 然后将由固溶强化的超级合金形成的第一填料材料焊接沉积在根区的第二部分中。 接着，将由沉淀强化的高温合金形成的第二填料材料熔合沉积在空腔的盖区域中。
