Technical Field

[0001] This utility model relates to the field of non-destructive testing technology for steel plates, specifically to an ultrasonic device for non-destructive testing of steel plates. Background Technology

[0002] Non-destructive testing (NDT) refers to methods that examine and test the structure, properties, and types, properties, quantities, shapes, locations, sizes, distributions, and changes of defects in the internal structure and surface of a material without damaging or affecting its performance or internal structure. This is achieved by utilizing changes in thermal, acoustic, optical, electrical, and magnetic responses caused by abnormalities or defects in the material's internal structure. In steel plate testing, ultrasonic equipment is often used for NDT. However, the current ultrasonic equipment is inconvenient to use because it requires manual application of coupling fluid and cleaning of the probe surface after testing. Utility Model Content
