EN ISO 17640

Ultrasonic Non-Destructive Testing

Ultrasonic testing (UT) detects internal flaws, wall thickness, and material discontinuities in metallic and composite components without damaging them. EN ISO 17640 covers manual UT of fusion-welded joints; phased-array (PAUT) and time-of-flight diffraction (TOFD) extend the technique to automated flaw sizing. UT is essential for pressure equipment, pipelines, and structural welds.

What it measures

Internal flaw detection (cracks, inclusions, porosity)
Flaw location, size, and orientation
Wall thickness measurement
Bond integrity in bonded structures
Weld root and fusion defects
