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 there are cracks perpendicular to the external surface but not open on the surface in the blind area, covering with a small angle probe (such as 45 °, 38 ° and double crystal probes) will have a greater risk 。<BR>
