... surface of the tube were identified as fluorides from the brazing flux by chemical analysis. The nature of the crack, potential for corrosion due to residual fluorides and residual swaging stress in the tube prior to brazing, confirmed that failure of the tube end was due to stress-corrosion cracking...

...-housing joint was revealed by visual examination. Fatigue marks, emanating from multiple crack origins on the inside surface of the housing at the brazed joint were revealed by further study of the fracture. A poor metallurgical bond was confirmed by the presence of large irregular voids, flux trapped...

...) and AWS type 1 brazing flux. According to the manufacturing procedure, following the brazing of the flange the V-notch should be cut, the threaded boss should be welded in place, and the subassembly should be solution treated and aged to the T6 temper. However, the rewelding of the threaded boss joint...
