Application Summary AI generated

This standard specifies the ultrasonic testing procedures for detecting internal discontinuities in welds made of austenitic steels and nickel-based alloys. It is applied in industries such as petrochemical, power generation, and pressure vessel manufacturing, where these materials are common due to their corrosion resistance. The standard addresses the unique challenges of coarse-grained microstructures that cause sound attenuation and scattering, providing specific techniques for reliable defect detection in these weld types.
