Guidelines for Non-destructive Inspection by Phased Array Ultrasonic Testing

The shipping Classification Society, ClassNK, has released its “Guidelines for Non-destructive Inspection by Phased Array Ultrasonic Testing”.

Phased array ultrasonic testing is an advanced non-destructive inspection technology that enables the visualising of flaw detection results and the digitising of the record-keeping process. It has higher detection performance for defects in materials and welded joints compared to conventional ultrasonic testing.

In recent years, the application of phased array ultrasonic testing in various industrial fields has been increasing, and it has also been gradually spreading in the shipbuilding field, taking advantage of the above features.

Based on the knowledge acquired from its R&D, ClassNK has comprehensively summarised the requirements for non-destructive inspection by phased array ultrasonic testing and specific flaw detection procedures for butt welded joints of carbon steels in the shipbuilding field into its guidelines.

These guidelines are available to download free of charge via ClassNK’s website for those who have registered for the ClassNK “My Page” service. To register for the “My Page” service free of charge, go to the ClassNK website and click on the “My Page Login” button.
