Description

Technical Field

[0001] The present invention relates to the technical field of weld detection, and in particular to an automatic weld detection device. Background Art

[0002] During the coal mining process, hydraulic supports need to be installed on the fully mechanized mining face to support the tunnel. The normal operation of the hydraulic supports is related to the safe operation of the tunnel. Since the workpieces of the hydraulic supports may produce dimensional deviations, pores, incomplete penetration, slag inclusions and other problems that affect the performance of the workpieces during welding, the weld defects of the workpieces need to be detected to ensure the quality and safety of the products.

[0003] In the related art, there are many conventional detection methods for weld detection, but the functions of each detection method are relatively single, and the methods applicable to different situations of the test piece are not fixed. For example, the penetration detection method in non-destructive testing can be applied to a variety of materials such as castings, forgings, welds, ceramics, etc., and the penetration detection is not affected by the geometric shape of the workpiece and the direction of the defect. It can also check the defects opening on the surface at the same time. The defect display of the penetration detection is intuitive, and the nature of the defect can be roughly determined. The detection sensitivity is high. However, the penetration detection requires other equipment to clean up impurities such as weld rust that may exist on the surface of the workpiece so that the steel pipe meets the detection standards. At the same time, the detection process is mainly manual, the labor workload is large, and the overall detection efficiency is low. Summary of the Invention

After proper adjustment, spray the penetrant onto the surface of the steel pipe to be tested through the infusion nozzle. In order to ensure uniform spraying of the penetrant, the steel pipe to be tested can also be rotated. The penetration temperature should be controlled between 15-50°C and the penetration time should not be less than 10 minutes.

[0071] Step 3: Move the position of the cleaning component by the second displacement plate, clean the excess penetrant on the steel pipe to be tested by rotating the roller brush, spray an appropriate amount of cleaning agent on the surface of the steel pipe to be tested through the infusion nozzle, and then perform a second cleaning on the surface of the steel pipe to be tested by moving the cleaning component and rotating the roller brush;

[0072] Step 4: After the inspection part of the steel pipe to be tested is cleaned, the developer can be sprayed. After the developer evaporates, it will absorb the penetrant in the defect, forming a red defect mark on a white background. It should be noted that the developer should be fully stirred before use and applied evenly through adjustment. The development time should be no less than 7 minutes.

[0073] Step 5: After applying the developer, the surface to be inspected needs to be dried. This can be done by using a dryer with hot air. The temperature of the surface to be inspected should not exceed 50°C, and the drying time should be 5-10 minutes.

[0074] Step 6: Observe the display marks within 7-30 minutes after applying the developer. When display marks appear, it is necessary to determine whether they are true defects or false defects. If necessary, observe with a low-power magnifying glass or conduct re-inspection;

[0075] Step 7: After the test is completed, in order to prevent the residual developer from corroding the surface of the weldment or affecting its use, the surface of the steel pipe to be tested should be cleaned by the cleaning component and the spray component to remove the residual developer.

[0076] The automated weld inspection device of the embodiment of the present invention is based on the principle of penetration testing and uses automated control to inspect the welds of the workpiece, which greatly simplifies the penetration testing process, shortens the testing time, saves manpower, and can effectively improve the testing efficiency, making up for the defects of slow penetration testing, multiple processes, and low degree of automation.
