How does the crane non-destructive testing？

Non-destructive testing of cranes is generally based on the selected testing method to determine the eligibility by reference to the corresponding standards, while non-destructive testing includes radiographic testing and ultrasonic testing. These two are commonly used non-destructive testing methods.

1, equipment volume comparison

Compared with the ultrasonic testing device, the radiation detecting device is bulky and heavy, and is not very convenient in the actual operation carrying process, so the ultrasonic detecting device is more convenient to carry.

2, the degree of difficulty of detection

Ultrasonic inspection of workpiece thickness range from a few millimeters to several meters is possible, and the higher the voltage of the radiation detection equipment, the more expensive the price, the more heat generated in the work, the higher the environmental requirements, in the actual detection application, the radiation detection The thickness of the steel plate is generally relatively economical within 25 mm.

3. Detection of defect effects

Generally speaking, the defects are mainly the defects of the butt welds of the main force-receiving members of the crane. The use of ultrasonic testing for cracks, rice penetration and unfused defects is better than the radiation detection effect.

4. Impact on personal health

In terms of the health effects of operators, radiography is actually a relatively dangerous radiation, so in terms of safety, ultrasonic testing is safer.

In the non-destructive testing of cranes, both types of detection methods can be used as inspections, but ultrasonic inspection is relatively safer and the detection range is wider.
