Background
Ultrasonic flaw detection is a method for detecting the flaw of a part by using the characteristic that ultrasonic energy penetrates into the depth of a metal material and is reflected at the edge of an interface when the ultrasonic energy enters another section from the section.
Ultrasonic waves have various modes when propagating in a medium, and longitudinal waves, transverse waves, surface waves and plate waves are most commonly used in inspection. The longitudinal wave can be used for detecting the defects of inclusions, cracks, pipe shrinkage, white spots, layering and the like in metal cast ingots, blanks, medium plates, large forgings and parts with simpler shapes; the transverse wave can be used for detecting the defects of circumferential and axial cracks, scratches, air holes in welding seams, slag inclusion, cracks, incomplete penetration and the like in the pipe; surface defects on a simply shaped casting can be detected with surface waves; defects in the sheet can be detected with plate waves.
