ISO 17640:2010 specifies techniques for the manual ultrasonic testing of fusion-welded joints in metallic materials of thickness greater than or equal to 8 mm which exhibit low ultrasonic attenuation (especially that due to scatter) at object temperatures from 0°C to 60°C. It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic.Where material-dependent ultrasonic values are specified in ISO 17640:2010, they are based on steels having an ultrasonic sound velocity of (5 920 ï¿1/2 50) m/s for longitudinal waves and (3 255 ï¿1/2 30) m/s for transverse waves.ISO 17640:2010 specifies four testing l
