ultrasonic flaw detection
Yantai Haige Machine Tools Co., Ltd. Was built in 1999, which specializes in producing steel finishing equipment, such as ultrasonic flaw detection, Series JY Bar Straightening Machine, Abrasive Belt Ginder, Drawing Machine, Shot Blasting Machine, Centerless Grinding Machine, CNC skiving and Roller Burnishing Machine and Auxiliary Machine etc. We also engage in continuous hard chrome plating equipment and heat treatment equipment.
There are multiple wave types when ultrasonic waves propagate in the medium. The most commonly used inspections are longitudinal waves, transverse waves, surface waves, and slab waves. It is that longitudinal waves are used to detect defects such as inclusions, cracks, shrinkage tubes, white spots, and delaminations in metal ingots, blanks, plates, large forgings, and articles with relatively simple shapes; shear waves can be used in pipes to detect circumferential and axial cracks, scratches, porosity in welds, slag inclusions, cracks, incomplete penetrations, etc. Surface flaws on castings with surface waves that can be easily detected; defects in sheet metal can be detected with plate waves.
(3)Accuracy on pinpointing the direction of reverberation, finding the size, shape and quality of the object
(4)Test on only one side

The way of flaw detection
Speed of flaw detection
When the external diameter of steel bar is 120mm, the detection speed is not less than 8 m / min.
Central transverse hole 0.8x 25mm (diameter < 180)
Central transverse hole 1.0 x 25mm / L 180 ≤ less than diameter ≤ 300)
Surface groove (depth × width × length 0.3X0.1X25mm)
