Ultrasonic flaw detection emits ultrasonic waves to the S690QL density steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the S690QL density steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
