| Project Title | VIRGINIA Class Submarine (VCS) SHAFT REPAIR |
| Service | NAVSEA |
| Command | NAVSEA / Naval Shipyards |
| Implementation Depot | PHNSY&IMF |
| Project Lead | Kurt Doehnert, SEA 04XP, kurt.doehnert@navy.mil |
| TI Goals Supported | P-1, S-2, C-3 |
| Focus Area | Metal Working |
| Platform General | Ship |
| Platform Specific | Submarine; VIRGINIA Class; Propulsion Shaft |
| Implemented Technology | Laser |
| Problem Definition | Currently, no repair process for the main shafts for VCS has been developed. |
| Proposed Solution | Laser cladding provides a viable solution to the issues of clad metal dilution and heat input in the current Submerged Arc Welding (SAW) based processes. The objectives of the VCS Shaft Repair program are to develop laser cladding parameters for both original manufacture and repair and refurbishment of VCS main propulsion shafts. |
| Expected Result | The laser cladding parameters, procedures, and tooling designs developed by iMAST will be transferred to Pearl Harbor Naval Shipyard. iMAST, PHNSY, and PNSY will work collaboratively to ensure that the cladding parameters and procedures developed by iMAS |
| Benefits | In addition to providing a currently unavailable repair capability for the VCS main shafts, the development of laser cladding based repair procedures will also improve the quality of the refurbished shafts and significantly minimize the time required for |
