Description

Technical Field

[0001] The invention relates to the technical field of welding strength detection of welded parts, and in particular to a welding seam detection device. Background Art

[0002] Welding seam quality inspection refers to the inspection of welding results, the purpose of which is to ensure the integrity, reliability, safety and usability of the welded structure. In addition to the requirements for welding technology and welding process, welding quality inspection is also an important part of the quality management of welded structures.

[0003] There are many welding inspection methods, which can be divided into sampling inspection and full inspection according to the number of welding inspections. When the welding quality is relatively stable and the process parameters are adjusted, the welding weld quality can be sampled and inspected. Full inspection is a 100% inspection of all welds or products. According to the welding inspection method, it can be divided into destructive inspection and non-destructive inspection. Destructive inspection usually includes mechanical properties experiments, chemical analysis tests, and metallographic inspection, while non-destructive inspection mainly includes appearance inspection, pressure resistance test and coloring inspection.

[0004] Depending on the actual welding situation, in actual production and processing, a combination of multiple welding detection methods is often used to conduct comprehensive inspection of welds.

[0005] The quality inspection of weld seams of welded parts requires the use of professional inspection equipment. However, due to the design limitations of existing inspection equipment, the following problems often occur during the inspection of different welded parts:

[0006] 1. The transfer of loading and unloading materials is inconvenient and the degree of automation of detection is low, which affects the detection efficiency.

[0007] 2. Poor adaptability to clamping of welded parts of different shapes. Specifically, welded parts of different shapes such as flat plates, pipes, shaft parts, etc. have significant differences in welding methods, weld positions, etc., and the weld detection methods required are also different. Therefore, during the detection process, the welded parts also need to be adaptively clamped according to the detection method.

[0008] 3. The detection method is single, and it is impossible to perform diversified detection on welds of different shapes and positions. Specifically, the detection of welds of welded parts includes both non-destructive detection such as size and shape detection and ultrasonic flaw detection, as well as destructive detection such as bending, drawing, and torsion tests. However, due to its single function, the existing detection equipment is often unable to perform the above-mentioned diversified detection at the same time; furthermore, the shapes of welds on different welded parts are also diverse, including long straight welds, circular welds, etc., and different detection methods are also required to detect these welds; in addition, when there are multiple welds on a welded part that need to be detected, the detection equipment is also required to have a certain degree of adjustability.
