Abstract：In order to ensure the safety of offshore oil and gas development， and to solve the problem of the key technology of underwater structure repair work， a friction welding system is supposed to be developed. In this year， the prototype of the system has been made out. and the welding procedure is also been researched. Besides that， a simulation technology of the prototype system has been carried out to ensure the technology can finally used underwater.
Key Words：Friction Hhydro Pillar Processing；Welding Process；Simulation Technology
