摘要： A method of forming alloy welding consumables for use in welding a base material includes providing a plurality of first welding consumables having a first diameter and a first chemical composition that closely matches the base material to be welded and providing a plurality of second welding consumables having the first diameter and a second chemical composition that is an alloy that is different from that of the base material. The method further includes winding a first quantity of the first welding consumables and a second quantity of the second welding consumables into a wound consumable having a chemical composition when welded that is a mixture of the base material and the alloy having a ratio equal to the ratio of the first quantity to the second quantity.

摘要： Methods of manufacturing or repairing a turbine blade or vane are described. The airfoil portions of these turbine components are typically manufactured by casting in a ceramic mold, and a surface made up of the cast airfoil and at the least the ceramic core serves as a build surface for a subsequent process of additively manufacturing the tip portions. The build surface is created by removing a top portion of the airfoil and the core, or by placing an ultra-thin shim on top of the airfoil and the core. The overhang projected by the shim is subsequently removed. These methods are not limited to turbine engine applications, but can be applied to any metallic object that can benefit from casting and additive manufacturing processes. The present disclosure also relates to finished and intermediate products prepared by these methods.
