ABSTRACT:
A weld-braze process is disclosed for forming high-strength metal joints using a localized heat source in combination with braze filler material. Braze filler material is sandwiched between the metal members to be joined at predetermined weld locations and the localized heat source is directed along one of the metal members in two offset passes at the predetermined weld locations to form a pair of parallel welds. The parallel welds form a pair of weld beads extending from one of the metal members through the braze filler material and into the other metal member with the braze filler material melting and forming a braze layer region intermediate the pair of weld beads to join the metal members. In one embodiment, the localized heat source comprises a computer numerically controlled laser energy beam. A method is disclosed for joining a cover sheet to a nozzle segment base in the manufacture of a high pressure nozzle segment for aircraft engines.
