REPAIR OF CASTING DEFECTS
A method of repairing defects in a casting formed from non-weldable or difficult-to-weld alloys is disclosed. The method includes removing the defect from the casting thereby forming a cavity in the casting, placing a filler material in the cavity and fusion welding the filler material in the cavity...

| description | A method of repairing defects in a casting formed from non-weldable or difficult-to-weld alloys is disclosed. The method includes removing the defect from the casting thereby forming a cavity in the casting, placing a filler material in the cavity and fusion welding the filler material in the cavity. The fusion welding produces surface cracks on the casting and sub-surface cracks in the casting. The method then includes brazing at least some of the surface cracks on the casting and processing the casting with a hot isostatic pressure (HIP) process to close at least some of the sub-surface cracks in the casting. |
