← TechnologyWhich risk increases when ultrasonic transducers are used to inspect structural steel beams exposed to high humidity constantly?
A)Corrosion initiation due to surface micro-cracking
B)Decoupling errors introduced with water ingress✓
C)Reflection interference from concrete aggregate
D)Attenuation causing near surface defects
💡 Explanation
When beams are constantly exposed to high humidity, water can penetrate into any small gaps between the transducer and the steel because the gel couplant gets diluted by moisture, leading to loss of signal coupling and erroneous readings. Therefore, errors introduced by water ingress increase, rather than from cracking, interference, or attenuation itself, which are separate physical mechanisms.
