This is a method and device for removing metal or depositing metal from the base metal of a vessel or performing crack and/or defect removal via excavation or other machine work in situ on cylindrical or other surfaces. In a one embodiment, the method and device is used for removing bonded alloy from carbon steel substrate in-situ. In one embodiment, the inventive system and method is used inside a coker unit to remove existing cladding along the weld seams and to prepare the machined area for application of new weld metal. In one embodiment, the method and device is used to deposit weld metal on a surface or in a groove. In one or more embodiments, the groove weld is then inspected for defects and repaired by the device, if required. In one or more embodiments, mapping is performed to autonomously direct the device.
A method for reconditioning a vessel comprising:
A system for decladding a vessel comprising:
The system of claim 5 wherein said control system directs said decladding device based on the surface profile characteristic data received from said scanner on the decladding device.
The system of claim 9 wherein said machining results in a 10 to 1 profile.
The system of claim 13 wherein said modular design is configured so that said decladding device may be reduced to several smaller modules that are capable of being transported through tight spaces such as access manways.
