12.4. Strength of Brazed Joints

Reference: Abbott, Richard. Analysis and Design of Composite and Metallic Flight Vehicle Structures 3 Edition, 2019

Brazing is a joining process that is not in general use for larger structure for aerospace applications because of process cost. There is no standard method for analysis of a brazed joint, however, NASA has made some efforts to create a reliable analysis methodology. This work has been under the stewardship of Dr. Yuri Flom and his work forms the basis for most of this section.

The prevailing opinion is that the brazed joint (if the joint is well designed and the parent materials and the filler metal are well selected) has an equal or greater strength than the parent metal.
