摘要
Abstract
During the manufacturing process of large-scale nuclear-level workpieces,an end weld with a special structure will be produced.This weld belongs to a Class I weld.The design technical conditions require radiographic testing of this weld.This research carried out radiographic testing process tests to address the technical problems that conventional radiographic testing methods cannot be implemented due to the limitations of the workpiece structure and space environment during radiographic testing of the weld.Through the γ-ray detection process experiment,the best position of the ray source and the best detection process are found,and the γ-ray detection results at the best position of the ray source and the best detection process state are compared with the conventional X-ray detection results to verify the detection effect of γ-rays.The test results prove that the testing process determined in this study can better solve the technical problems existing in radiographic testing of the weld and lay a technical foundation for ensuring the quality of the weld.关键词
