核工程薄壁不锈钢焊缝交流电磁场检测模拟验证
Research on Simulation Verification of Alternating Current Field Measurement Testing of Thin-walled Austenitic Stainless Steel Welds in Nuclear Power Plant
摘要
Abstract
China Nuclear Power Engineering Co.,Ltd.led the research and development of a set of ACFM technology in-cluding probe,system equipment,methods and processes for the volume detection of thin-wall(≤3.5 mm)stainless steel welds in a national key engineering project.In this paper,a simulation test with different types,sizes and positions of defects was designed.ACFM and RT blind test were carried out respectively,and the test results were compared and analyzed.The verification test results show that the developed ACFM detection system and process are stable and effective,and can realize the rapid and effective detection of excessive defects in thin-wall stainless steel welds.For the super-standard defects in simulated test blocks,ACFM technology has no lower detection capability than RT.ACFM technology is sensitive to weld surface state,proper grinding does not affect the detection of defects.The research and application of high sensitivity ACFM detection provides a new idea for the detection of internal defects in welds of thin-walled non-ferromagnetic materials.关键词
