The endoscope can effectively improve the efficiency of staff to check equipment problems, and can check the quality defects such as corrosion, rust spots, iron filings and foreign matters, butt welds and so on. So how does it determine the problems of the equipment? It can be seen from the following aspects that there is a problem with the equipment.
When the light beam irradiates the surface of the detected object, black or bright lines are observed and magnified by a certain number of times. When irregular edges are found around the lines, it can be determined as cracks.
Under the irradiation of the light beam, it is observed that there are massive and point shaped unsmooth surfaces, and slight unevenness under a certain magnification is corrosion.
3. Welding leakage
When the beam is irradiated at an appropriate angle, it is observed that it is connected with the molten metal, and the bulge without boundary is welding leakage.
When the beam is irradiated in parallel, it is found that there is a shadow behind the convex part; When the beam irradiation angle is changed, it is found that there is an obvious boundary between the convex part of the surface and the surrounding tested object, it can be determined as peeling.
5. Cables and scratches
Under the irradiation of light beam, if there is a regular continuous long line on the surface of the measured object, it is determined as a stay wire.
When the light beam is irradiated, the smooth non concave convex surface with different color from the surrounding tested object can be determined as spots.
