ULTRASONIC CONTROL OF WELDED COMPOUNDS
Welded joints are the most common object of ultrasonic testing. Mobility, harmlessness to others and personnel, high sensitivity to internal and surface defects (including planar ones, ie, cracks and fissures) are the main advantages of ultrasonic testing of welded joints before other non-destructive methods. At the same time, the welded joint is complicated for ultrasonic testing.
