[MW:29145] Repairing a brazed crack by TIG / MIG Welding

Revered Experts
Please enlighten on the following:
1) We are repairing aero turbine shrouds by detecting cracks on them and then repairing surface cracks by conducting vacuum brazing.
2) However, this does not last long and when the shrouds return for repairs can we fill in the brazed cracks by TIG / MIG welding on the brazed surface.
3) I will not be able to share BPS or WPS for proprietory constraints.
4) Alternately the question may be that Can we TIG or MIG weld on the brazed joint to repair.
