Immersion Testing (Ultrasonic)
Ultrasonic testing method where both the transducer and test piece are immersed in water or other liquid couplant. Immersion testing provides excellent coupling and allows for automated scanning and precise positioning. It is ideal for detailed inspection of complex geometries and batch inspection of similar parts. The liquid couplant provides superior coupling compared to gel couplants but requires more equipment.
