摘要： Methods for material build-up on a tip of a blade of a gas turbine engine are provided. The method can include inserting a material supply and an inflatable bladder between the tip and a shroud such that the material supply is exposed to the tip and the inflatable bladder is positioned between the material supply and a shroud, inflating the inflatable bladder to force contact between the material supply and the tip, and causing relative movement between the material supply and the tip. The relative movement, in combination with the radial biased contact between the material supply and the tip, creates heat through friction. As such, the relative movement can frictionally weld new material from the material supply onto the tip of the blade. For example, the heat created can be sufficient to melt the surface of the material supply to transfer material from the material supply to the tip.

摘要： A method of impact welding a flyer to a hollow component is provided. The method includes providing the component made of a first material and including a cavity where a weld site is disposed on a first side of the component. An incompressible material is packed against a second side of the component opposite the first side facing the cavity. A flyer made of a second material is positioned onto the weld site. The flyer is then impact welded to the component. The incompressible material prevents the deformation of the component during the impact welding. A method of impact welding a cover plate to a component is provided as well as a support system for welding repair of hollow components.
