Nuclear power station BOSS head welding seam detection method, system, equipment and medium

Abstract

The invention belongs to the technical field of nuclear power station maintenance optimization, and particularly relates to a nuclear power station BOSS head welding seam detection method, system and equipment and a medium. The nuclear power station BOSS head welding seam detection method comprises the steps that a control array probe scans a main body welding seam from a mother pipe side to obtain a first detection waveform of the main body welding seam; a phased array probe scans a root weld of the BOSS head weld to obtain a second detection waveform of a root weld area; the phased array probe scans a top welding seam of the BOSS head welding seam to obtain a third detection waveform of the top welding seam; a preset comparison waveform is acquired, the preset comparison waveform is compared with the first detection waveform, and a first defect value of the main body welding seam is determined; the preset comparison waveform is compared with the second detection waveform, and a second defect value of the root welding seam is determined; and the preset comparison waveform is compared with the third detection waveform to determine a third defect value of the top welding seam. According to the nuclear power station BOSS head welding seam detection method, the detection precision of the nuclear power station BOSS head is improved.

Description

technical field [0001] The invention belongs to the technical field of maintenance and optimization of nuclear power plants, and in particular relates to a method, system, equipment and medium for detecting weld seams of BOSS heads of nuclear power plants. Background technique [0002] During the operation of nuclear power plants, pipelines are needed to transport media such as liquids and gases. A large number of reinforced BOSS head weld structures are used at the connection between the main circuit pipeline of the nuclear power plant pipeline and the secondary and tertiary component pipelines, that is, the connection between the main pipe and branch pipes of the nuclear power plant is connected by BOSS head welds. The BOSS head weld needs to withstand the same temperature and pressure as the main pipe, and the BOSS head weld is prone to gaps during manufacturing and operation, which will cause leakage of nuclear power plant pipelines and seriously affect the safe operatio...
