Ultrasonic Tandem Reflector Reconstruction
Ultrasonic tandem reflector reconstruction uses two probes for angled through-transmission and depth determination of faulty interfaces inside the workpiece.
Physical-Chemical Working Principle
Ultrasonic tandem reflector reconstruction uses two ultrasonic detectors, a transmitter and a receiver. The transmitter sends an ultrasonic wave at an angle, and the receiver picks up the reflected wave. The time difference between sending and receiving gives the depth of the flaw.
Metallurgical Relevance & Welding Risks
This method allows precise depth determination of planar flaws, such as lack of fusion or laminations. An inaccurate instrument can give false depth readings, leading to misinterpretation and potential defects.
Workshop Practice & Procedures
Use ultrasonic tandem reflector reconstruction when inspecting weld surfaces, especially when depth determination is required. Make sure the instrument is correctly calibrated and used. The angles of the transmitter and receiver must be set precisely to ensure accurate measurement.
