Non-destructive testing of welds. Ultrasonic testing. Techniques, testing levels, and assessmentWhat is this standard about? This international standard specifies techniques for the manual ultrasonic testing of fusion welded joints in metallic materials thicker than or equal to 8mm which exhibit low ultrasonic attenuation. The standards guidelines detail specific testing techniques for metals that show weakened ultrasonic levels at temperatures of up to 60C. Its mainly designed for full penetration weld joints where both the welded and parent
