Nowadays, as people'srequirements for pipeline quality become more and more stringent,non-destructive testing for pipeline welding is becoming more and morenecessary. Manufacturers expect high-quality products and reduce the loss oflater leaks repairing , so regular non-destructive inspection with the use ofportable endoscopes is particularlyimportant.
The former traditional welding technology was often relatively backward,and various defects were prone to appear during the welding process due tovarious reasons. Common defects such as: incomplete fusion at the interface,foreign matter, undercut at the joint, or burrs and pores, etc.; These defectsoften appear inside the pipeline, which cannot be discerned by the naked eye,not to mention that they will be affected by factors such as the environment,light or line of sight, which will easily affect the quality of the product andshorten the service life of the equipment, more seriously, safety incident mayoccur;
Therefore, it is necessary and essential to conduct regular qualityinspections of welding parts. Among non-destructive testing equipments, portableendoscopes are more widely used, which can directly perform quality inspectionsof the inside of welding parts, and timely check for leaks, thus to reduce theloss of the equipments during manufacture and use. And prolong the service lifeof the equipment and improve the performance of the equipment;
In the process of using the endoscopes to detect, the portable endoscopescan accurately determine various welding defects at the welded joints, such asair holes, foreign objects, cracks, unoccupied, etc., no matter how complicatedand dark the pipeline environment is, it can be easily dealt with.Because theportable endoscopes are with adjustable LED lights and transmitted by theprobes, then display the internal situation clearly on the external displayscreen; And there is an electric joystick on the handle to control the topcamera probe 360° Rotate in all directions, so that you can quickly and easily checkthe quality problems of the welding position;
As a non-destructive testing tool, the portable endoscopes have becomeessential tools for welding testing because of its simple operation, fastquality testing, and rich testing functions;
Nowadays, after years of development of portable endoscopes, the scope ofuse of endoscopes is not only limited to welding technology, but also play abig role in the industrial production, precision casting, aviation technology,pipeline transportation, etc. Because they can carry out non-destructivetesting without disassembly, so that quality problems can be effectivelycontrolled, and the endoscopes have gradually become conventionalnon-destructive testing methods.
