High temperature brazing fixture and method of manufacture

A high temperature brazing fixture for a component, the high temperature brazing fixture comprising:

• a first frame member made from a superalloy, the superalloy having a coefficient of thermal expansion sufficiently similar to that of the component so as to not cause the component or its parts to be moved out of tolerance during brazing operations;
• a second frame member made from the superalloy;
• a first support member made from the superalloy and configured to interface with and support at least a first portion of the component, the first support member mechanically coupled to the first frame member and to the second frame member;
• a first tab that extends from one of the first support member and the first frame member and passes through the other of the first support member and the first frame member;
• a first tab lock between the first tab and the other of the first support member and the first frame member;
• a second tab that extends from one of the first support member and the second frame member and passes through the other of the first support member and the second frame member;
• a second tab lock between the second tab and the other of the first support member and the second frame member;
• a first positioning member made from the superalloy and configured to interface with and position at least a first location of or hold a first dimension of the component, the first positioning member mechanically coupled to the first frame member and to the second frame member;
• a third tab that extends from one of the first positioning member and the first frame member and passes through the other of the first positioning member and the first frame member;
• a third tab lock between the third tab and the other of the first positioning member and the first frame member;
• a fourth tab that extends from one of the first positioning member and the second frame member and passes through the other of the first positioning member and the second frame member;
• a fourth tab lock between the fourth tab and the other of the first positioning member and the second frame member;
• wherein at least one of the first tab, the second tab, the third tab, and the fourth tab is formed as a T-tab;
• and
• wherein at least one of the first tab lock, the second tab lock, the third tab lock, and the fourth tab comprises at least one half lock that partially surrounds the T-tab and is wedged in a narrowed portion of the T-tab.
