摘要：
We decided to investigate the correlation between the result of the enlarged indication pattern using the penetrant inspection test which is an auxiliary technique for visual inspection and the break position. As a result, except for weld fracture, the following was found about the correlation. (1) In the specimen in which the enlarged instruction pattern appeared, the vicinity of the heat affected zone breaks or the base metal fractures. (2) In the test piece without the enlarged instruction pattern, the base material breaks. © 2020 Architectural Institute of Japan. All rights reserved.
