WebWeld testing. Simple high frequency eddy current testers have been used for some time to detect toe cracks in ferrous welds. The method has the advantage of being able to detect cracks through paint layers. The disadvantages lie in the high noise levels caused by permeability changes in the weld and lift-off noise from rough cap surfaces. WebThe eddy current testing we are talking about here is used to detect the existence of cracks and other defects in steel pipe. Steel pipe through the eddy current flaw test equipment, the resulting signal is lower than the alarm level, then the pipe can be recognized as a qualified inspection. Steel pipe through the eddy current flaw test ...
WebOct 1, 2008 · The eddy current values vary only due to changes in metallurgical phase. In case of 304 and 321 steels the eddy current values have small changes up to 20% of cold reduction. Then it increases sharply after 20% reduction and remains so up to 50%. A similar pattern can be observed in GOST-12Ch21N5G2STL steel.
