Welding system and method of nuclear engineering pipe under radiation environment

Abstract

The invention belongs to the technical field of nuclear engineering pipeline welding. In order to achieve smooth repairing and welding of the nuclear engineering pipeline under the radiation environment and ensure the efficiency and quality of the welding operation, the invention discloses a welding system and method of the nuclear engineering pipe under the radiation environment. The welding system includes a first welding unit, a second welding unit and a control unit; the first welding unit is connected to the pipeline to be welded, the second welding unit is connected to a simulation pipeline, and the control unit is simultaneously connected to the first welding unit and the second welding unit and controls a first welding machine and a second welding machine to perform synchronous welding operation; and the simulation pipeline is located in a non-radiation area, and the welding condition is the same as the welding condition of the pipeline to be welded. When the welding system isused for repairing and welding the nuclear engineering pipeline under the radiation environment, the standing time of an operator in the radiation environment can be reduced, the protection of the operator can be improved, the welding operation can be completed quickly and smoothly, and the welding efficiency and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of welding of nuclear engineering pipelines, and in particular relates to a welding system and method for nuclear engineering pipelines in a radiation environment. Background technique [0002] A large number of pipelines are laid in nuclear power plants, and these pipelines are distributed in different environmental areas, including pipelines located in high-radiation environmental areas. During the initial laying and installation process of pipelines located in the radiation environment area, there is no special difference from the pipeline laying operation in other environmental areas, and the on-site welding installation can be carried out by welding personnel or welding machines. [0003] However, in the later stage of nuclear power plant operation, if the pipeline in the radiation environment is damaged and needs to be repaired and welded, it is necessary to quickly and accurately complete the pipeline...

Problems solved by technology

In this way, if welders work in a radiation environment for a long time, even with the help of radiation protection suits, it will pose a great threat to personal safety and affect the life safety of welders. If the stay time of welders in the radiation environment is shortened, by Multiple welders take turns to enter the radiation environment to repair and weld the pipeline to be welded, which will lead to poor welding continuity and affect the quality of welding.
