Description

Technical Field

[0001] This utility model relates to the field of steel structure welding inspection technology, specifically a non-destructive testing device for steel structure welding. Background Technology

[0002] Steel structure is a building structure that uses steel as the main load-bearing component. It is widely used in industrial plants, commercial buildings, public facilities, bridges, high-rise buildings and other fields. Non-destructive testing equipment for steel structure welding is an important tool to ensure the quality of steel structure welding. It can detect internal and surface defects without damaging the object being tested.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Non-destructive Testing Device for Steel Structure Welding," patent application number: 202220779307.6. It includes a base and a testing component. A support platform is provided on the upper right side of the base, and a testing power component is installed on the upper end of the support platform. The testing power component includes a motor, a rotating shaft, and a rotating rod. The rotating end of the motor is connected to the rotating shaft, and a rotating rod is provided outside the rotating shaft. A testing block is connected to the left end of the rotating rod. The testing component is located on the upper end of the testing block, and the upper end of the limiting spring is connected to the testing block. The steel structure welding non-destructive testing device includes a base and a testing component. The upper end of the limiting spring is connected to the testing block. Compared to existing non-destructive testing (NDT) devices for steel structure welding, this structural welding device performs omnidirectional inspection by circling the test object with a test block, avoiding omissions and overlooking product quality. The clamping block, under the action of a compression spring, effectively holds the weld, facilitating subsequent inspection. A tapping block strikes the weld at a fixed frequency, analyzing the sound to determine if the weld is properly filled. In contrast, the aforementioned testing devices require manual positioning of the steel structure, which is not only inefficient but also cumbersome, impacting the overall efficiency of weld inspection.

[0004] Therefore, the detection device needs to be redesigned and modified to effectively prevent the inconvenience of manual limit switching. Utility Model Content
