GB/T 40733-2021Non-destructive testing of welds - Ultrasonic testing - Use of automated phased array technology (English PDF)

1 Scope

This document specifies the semi-automatic or fully automatic phased array ultrasonic testing of the fusion welded joints of metal materials with a base metal thickness of not less than 6mm.

This document is applicable to full penetration welded joints such as low-alloy or fine-grained steel plates, pipes and containers for base materials and welds, and welding of other materials

The detection of joints can also be used as a reference.

This document gives the advantages and advantages of discontinuity in detection, positioning, quantification and characterization of phased array ultrasonic technology when detecting fusion welded joints.

Limitation. In manufacturing process inspection, pre-service inspection and in-service inspection, phased array ultrasonic technology can be independent or combined with other non-destructive testing methods or technologies

Used in combination.

This document specifies 4 detection levels, with different levels corresponding to different defect detection rates.

The provisions of this document can be based on the length and the highest echo amplitude (equivalent reflector size), or the length and height are not continuous.

This document does not specify discontinuous acceptance levels.

This document does not apply to the automatic phase of welds in the manufacturing process of steel products specified in ISO 10893-8, ISO 10893-11 and ISO 3183.
