Small-diameter pipe inside weld surface defect identification device

Abstract

The invention provides a small-diameter pipe inside weld surface defect identification device. The device comprises a computer, an industrial camera, an adapter, an industrial endoscope, a mobile portable light source, an endoscope fixing clamp and a pipe fitting to be detected. The industrial camera is connected with the computer. One end of the adapter is connected with the industrial camera, the other end is connected with the industrial endoscope, and the adapter can be used for acquiring weld images. The mobile portable light source is connected with the industrial endoscope and used for providing lighting inside the pipe. The endoscope fixing clamp is connected with the endoscope and used for center positioning, upward and downward adjustment and positioning and 360 degrees of rotation of the endoscope. Identification detection of the weld surface defects inside the pipe fitting to be detected is completed.

Description

technical field [0001] The invention relates to a detection device for welding seam defects, in particular to a detection device for surface defects of weld seams in small-diameter pipes. The device is suitable for the detection and identification of internal weld seam welding defects at the small mouth pipes of energy-transforming equipment such as pipelines, boilers and headers, and belongs to the field of non-destructive testing. Background technique [0002] With the development of my country's industrial industry, boilers, pipes, headers and other energy-transforming equipment are the key components to withstand high temperature and high pressure, and their manufacturing quality has attracted more and more attention. Since the transducer equipment has to bear not only the internal pressure caused by the action of the medium, but also the stress caused by the temperature difference between the inside and the outside, failure and damage are likely to occur in the internal...

Problems solved by technology

[0003] At present, there is no effective detection method for the welding quality of the internal weld surface of small-diameter pipes, and manual detection methods are mostly used

Since the inspectors stare at the moving welds on the screen for a long time, it is easy to cause eye fatigue and missed inspections, and the quality, skills and experience of the inspectors are different, and the grasp of the quality inspection standards will inevitably be biased, resulting in the detection results being affected by the inspectors. The subjective influence factors are relatively large, and it is difficult to make accurate and quantitative judgments on defects
