Abstract
A method and system that includes generation of an energy beam. The energy beam may be generated from a focused energy source. Additionally, the energy beam may be directed towards a pre-sintered preform. The pre-sintered preform may be made of a braze material and may seal a hole that may be located in a turbine component.
Claims20
A system, comprising:
- a focused energy source configured to generate an energy beam;
- and
- a brazing controller configured to control brazing of a pre-sintered preform via alteration of at least one performance characteristic of the focused energy source to adjust the energy beam for focused brazing of the pre-sintered preform.
A system, comprising:
- a turbine component comprising a superalloy;
- and
- a pre-sintered preform (PSP) braze material disposed on a portion of the turbine component and bonded to the turbine component via brazing, wherein the portion of the turbine component not bonded to the PSP braze material is materially unchanged due to the brazing.
A method, comprising:
- generating an energy beam from a focused energy source;
- and
- directing the energy beam toward a pre-sintered preform of a braze material to seal a hole in a turbine component.
