Non-destructive examination of welds. Ultrasonic examination of welded joints

This European Standard specifies methods for the manual ultrasonic examination of fusion welded joints in metallic materials equal to and above 8 mm thick which exhibit low ultrasonic attenuation (especially that due to scatter). It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic. Where specified and appropriate, techniques may also be used : - on materials other than those stated ; - on partial penetration welds ; - with automated equipment by agreement between the contracting parties. Where material dependent ultrasonic values are specified in this standard they are based on steels having an ultrasonic sound velocity of 5920 n 50 m/s for longitudinal waves, and 3255 n 30 m/s for transverse waves. This is to be taken into account when examining materials with a different velocity. The standard specifies four examination levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of examination levels A, B and C is given in annex A. The requirements
