Application of industrial electronic borescope in the inspection of welds
With the development of industrial technology, welding technology is widely used in various fields, such as aerospace, petrochemical, shipbuilding, etc. However, various defects may occur during the welding process, such as porosity, slag inclusion, non-fusion, etc., and the existence of these defects will have a serious impact on the reliability and safety of the structure. Therefore, the inspection of welds is particularly important. The traditional detection method is to inspect it by visual observation or simple tools, but for some hard-to-reach or hidden parts, this method often does not achieve the desired effect. In order to solve this problem, industrial electronic endoscopes are widely used in weld inspection as an advanced inspection tool.
Industrial electronic endoscope is a kind of detection equipment integrating optical, mechanical, electrical and other technologies, which can go deep into the interior of the object to observe and help us find internal problems. The device consists of parts such as lens, lighting, image processing, and display. The lens is the core component of the endoscope, which is able to transmit the image of the surface of the object to the image processing part. The illumination part is responsible for providing enough light for the lens to capture a clear image of the surface of the object. The image processing part processes and optimizes the received image, and finally presents the image to the operator through the display part.
In weld inspection, the advantages of industrial electronic endoscopes are mainly manifested in the following aspects. First of all, it has the advantage of non-destructive inspection, which can be carried out without damaging the workpiece, avoiding the additional cost and time associated with inspection. Secondly, it has the characteristics of high precision and high resolution, and can clearly observe the subtle defects inside the weld, such as porosity, slag inclusion, etc., which provides an accurate basis for the judgment and classification of defects. In addition, the industrial electronic borescope can also record and take pictures in real time, which is convenient for the operator to record and save the inspection results.
In practical applications, the use of industrial electronic endoscopes is as follows. First, the operator needs to insert the endoscope probe into the weld and then observe the condition inside the weld by adjusting the angle and depth of the probe. If a defect is found, the operator can further observe information such as the shape, size, and location of the defect by adjusting the focal length and illumination of the lens. At the same time, defects can be classified and rated by image processing and display sections. Finally, the operator needs to record the test results and analyze them to provide a basis for subsequent process improvement and quality assessment.
It should be noted that although industrial electronic endoscopes have many advantages, they also have some limitations in use. For example, for some large or complex structures, it may take a lot of time and manpower to complete the inspection work. In addition, the use of endoscopes may be limited for some special materials or environments, such as high temperature, high pressure and other harsh conditions. Therefore, it is necessary to select the appropriate detection methods and tools according to the specific situation in the practical application.
In summary, industrial electronic endoscopes have important application value in weld inspection. It not only improves the accuracy and reliability of detection, but also provides strong support for quality control and safety assurance in the production process. With the continuous advancement of technology and the expansion of application fields, industrial electronic endoscopes will play an important role in more fields.
