Method for testing parts, especially of nuclear plants, by means of eddy current |
摘要 |
Defect detection in testing pipes, particularly in heat exchangers of nuclear reactors by means of eddy current in which interference influences due to the design are suppressed by measurements with different frequencies and the frequencies interlinked to give a signal only if there is a defect indication.
