Description

Technical Field

[0001] The utility model relates to the technical field of rust layer thickness detection, in particular to a device for detecting the thickness of rust layer on weathering steel. Background Art

[0002] Weathering steel, also known as atmospheric corrosion resistant steel, is a low-alloy steel series between ordinary steel and stainless steel. According to the requirements of the regulations, due to the influence of various environments during the operation of weathering steel materials, its corrosion status needs to be regularly inspected to ensure that the degree of corrosion is always within the design allowable corrosion margin. For example, the design corrosion margin of weathering steel towers for transmission lines is 0.5mm. According to the test, when the corrosion thinning of the tower body reaches 80% of the corrosion margin, an overall stress assessment of the tower is required.

[0003] At present, when detecting the thickness of the rust layer of weathering steel, the thickness of the rust layer of the weathering steel is generally calculated based on the feedback of the electromagnetic ultrasonic signal. However, due to the different thickness of the rust layer of the weathering steel, different points on the surface of the weathering steel need to be detected. Therefore, during the detection process, these points need to be marked first, and then detected in turn. The work efficiency is low, and the detector is generally manually held for detection and recording at the same time, which is cumbersome to operate and reduces the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
