Abstract
A method is provided for brazing of porous metallic materials while avoiding wicking of braze material away from the braze joint. The porous material is locally melted and solidified to provide solid material in the region of the braze joint. The braze joint is machined in this solidified material. Brazing is then performed on nonporous surfaces of the porous materials. This method provides effective braze joints in porous material while avoiding the introduction of any foreign matter into the structure.
