摘要
Abstract
To address the volumetric inspection requirements for thin-walled austenitic stainless steel welds in nuclear power plants,a comprehensive Alternating Current Field Measurement(ACFM)technology system was established,encompassing theoretical and simulation research,probe and system equipment,as well as methods and processes.This paper conducts a blind test comparison between Radiographic Testing(RT)and ACFM on a simulated test block for system design.The experimental results demonstrate that:The ACFM system operates stably and reliably,enabling efficient and effective screening of exceeding defects in thin-walled stainless steel welds;The ACFM exhibits defect detection capability exceeding to RT,with an efficiency improvement of over three times;ACFM technology is sensitive to weld surface state,and cannot provide qualitative or precise quantitative analysis.关键词
