Plan titanium vacuum annealing around oxygen pickup, surface condition, furnace cleanliness and alpha-case inspection before accepting the production load.
Evaluate vacuum brazing repair through defect cause, remaining wall, filler history, whole-assembly reheating and repeat inspection before a second cycle.
Plan copper-to-copper vacuum brazing with verified filler selection, hot joint clearance, fixture restraint and load-based process qualification.
Design vacuum brazing vent paths for blind holes and enclosed pockets. Review evacuation access, filler closure, cleaning and evidence before production.
Plan 17-4 PH aging treatment around incoming condition, required properties, part-temperature evidence and dimensional checks before releasing a batch.
