Abstract
Abstract
Present the method that using the ACFM to test the spherical tank which had appeared the differential settlement. First introduced the principle and the system composition of the ACFM, by using which, the pillar fillet weld of the LPG spherical tank had been tested, and then the quantitative evaluation of the weld cracks had been get out. After analyzed deeply, the reliability of the ACFM when testing the pillar fillet weld of the spherical tank had been proved, in additionally, the causes of how the cracks come out had been given, too.
