CNPEC可以严格地按照程序执行repeat inspection。C

CNPEC be strictly in accordance with the program execution repeat inspection. <BR>Technically give information CNPEC: 60 ° and 70 ° of the probe scanning probe outer surface of the blind spot generated, priority should be given a large angle scanning probe attached to a coverage hole exists in the outer surface of the inner surface of the vertical, such as but not blind fruit crack opening, if the small angle scan to cover the probe (for example 45 °, 38 ° and double crystal probes) there is a big risk blind crack echo amplitude may be relatively low in this case.

CNPEC can strictly follow the procedure to perform the res inspection.<BR>CNPEC technically gives a technical reminder: 60-degree probe and 70-degree probe on the outer surface scanning resulting in the blind area, should give priority to the use of large-angle probe for additional scanning, to cover the blind area, such as the blind area fruit perpendicular to the outer surface but not in the surface of the opening of the crack defects, if covered by small angle probe scanning (e.g. 45 degrees, The blind area of 38 degrees and dual crystal probes is at greater risk, in which case the range of crack echo may be relatively low.

Cnpec can perform repeat inspection in strict accordance with the program.<BR>Cnpec gives a technical reminder: for the blind area generated by scanning 60 ° probe and 70 ° probe on the external surface, it is preferred to use a large angle probe for additional scanning to cover the blind area. For example, if the blind area is covered by a small angle probe (such as 45 °, 38 ° and twin crystal probes), the blind area will be larger In this case, the crack echo amplitude may be relatively low<BR>
