Problems solved by technology
In this way, inspectors need to work in a radiation environment for a long time. At this time, even with the help of radiation protection suits, it will pose a great threat to personal safety and affect the life safety of inspectors. Moreover, it will be inconvenient to operate due to wearing protective devices for inspection. , resulting in longer inspection cycles and lower work efficiency, and welded pipes in a radiation environment cannot be subjected to destructive tests

Embodiment Construction
[0025] The technical scheme of the present invention will be further introduced below by taking the welding repair of pipelines arranged in the horizontal direction in a nuclear power radiation environment as an example.
[0026] combine figure 1 As shown, adopting the method of the present invention to carry out the welding operation and the specific steps of the welding quality inspection of the pipeline arranged in the radiation environment along the horizontal direction are:
[0027] Step S1, perform actual welding operation of the pipeline to be welded in the radiation area, and collect and record welding data.
[0028] The welding personnel install the automatic welding equipment on the pipes to be welded in the radiation area, and use the automatic welding equipment to automatically weld the pipes to be welded in the radiation area according to welding requirements. At the same time, during the welding process, the actual welding parameters of the automatic welding are...

The invention belongs to the technical field of nuclear power welding detection, and discloses a welding quality detection method of a welding piece in a radiation environment. The method has the advantages that the welding quality of the welding piece in the radiation environment can be detected, and the detection efficiency and the detection quality can be guaranteed. The detection method specifically comprises S1, actual welding operation is conducted on a to-be-welded piece in a radiation region, and welding data are collected and recorded; S2, a simulation welding piece is established; S3, welding operation and welding quality detection are conducted on the simulation welding piece; and S4, the welding quality of the to-be-welded piece in the radiation region is detected. According tothe method, the welding piece in the radiation environment is subjected to welding operation and welding quality detection, so that the welding quality detection of the welding piece in the radiationregion can be rapidly and accurately completed, and the detection efficiency and detection quality on quality of the welding piece are improved.
Description
technical field [0001] The invention belongs to the technical field of nuclear power welding detection, and in particular relates to a method for detecting the welding quality of welded parts 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. It is sufficient to use welding personnel or welding machines for on-site welding installation and welding quality inspection. [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 comp...
