Description

Direct probe contact method coupling device

Technical Field

The disclosure relates to the technical field of workpiece flaw detection, in particular to a direct probe contact method coupling device.

Background

Ultrasonic flaw detection is a detection method that uses physical characteristics such as propagation, reflection, and attenuation of ultrasonic waves in an object to find defects. It can inspect the surface and inner defects of metal material and part of non-metal material, such as cracks, unfused, incomplete penetration, slag inclusion, air holes and other defects in welding seam. In ultrasonic flaw detection, ultrasonic flaw detection is classified into a direct contact method and a liquid immersion method according to the contact mode of a probe and a workpiece.

The liquid immersion method is a flaw detection method that a workpiece and a probe head are immersed in a coupling liquid, and the probe does not contact the workpiece. The liquid immersion method needs a large water tank for containing coupling liquid, so that the method is mainly used for complex workpieces and workpieces with oversized single weight, and the workpieces are not easy to turn over and operate in the coupling liquid, so that the contact method is mainly used for flaw detection. The coupling agent commonly used in the contact method is selected from engine oil, transformer oil, glycerol, water and the like. Compared with couplants such as glycerol and engine oil, the coupling agent has the advantages that the water is pollution-free, corrosion-free, low in price and easy to obtain on the surface of the bar to be detected, the bar to be detected is smoother when being scanned, and missed detection is not easy to occur, but when the bar to be detected is coupled by a contact method, the coupling effect cannot be ensured when the conventional device is adopted due to the weight limitation of the geometrical shape monomer.

Therefore, it is necessary to design a direct probe contact method coupling device for ultrasonic inspection of complex structural members and heavy workpieces.
