1、Radiographic inspection method. The main principle of the radiographic flaw detection method is to use the ray emitted by the ray source to penetrate the weld seam, photosensitive on the film, and the image of the weld seam defect will be displayed.
2、Ultrasonic flaw detection inspection method. Compared with radiographic flaw detection, ultrasonic flaw detection has certain advantages, such as high sensitivity, low cost, short cycle, high efficiency, and mainly harmless to human body. However, the ultrasonic flaw detection inspection method also has certain defects. For example, the lack of line display is not intuitive enough, and the technical and experience requirements of the flaw detection personnel are relatively high.
3. Penetration inspection method. The main inspection principle of the penetrant inspection method is to coat the surface of the inspected weld with a pigment or phosphor penetrant, so that it penetrates into the opening defects, cleans up the excess penetrant, and applies a color developer after drying, so as to observe the defect traces.
4. Magnetic flaw detection inspection method. Magnetic inspection method and penetrant inspection method are both a kind of surface quality inspection methods of weldment, which are mainly used to inspect the surface and nearby surface defects. The above-mentioned visual inspection, compactness inspection, and non-destructive inspection are all non-destructive inspections of welded components, and welding inspections include destructive and non-destructive inspections. For destructive inspection, it can be divided into mechanical property inspection, chemical analysis and experiment, metallographic inspection, weldability inspection and other inspection methods.
The pipeline automatic welding equipment (pipeline intelligent welding equipment) developed and produced by Tianjin Yixin Pipe Equipment Co., Ltd. can be used to realize the automatic welding of pipelines in all positions(AUTOMATIC PIPE WELDER). The welding efficiency is high, and the weld seam can meet various flaw detection requirements and can be widely used. For petrochemical, natural gas and other long-distance pipelines, heat, water pipes, etc( automatic mig pipe welder)., it has greatly improved the efficiency and quality of pipeline installation engineering, and has been widely recognized by customers (automated pipe welder).
Automatic welding equipment has high efficiency and stable welding quality. It does not require high labor requirements. As long as there are basic welders, it can be operated. It is understood that most projects use manual welding, which is difficult to ensure the quality and efficiency of pipeline construction. . However, the quality of automatic welding is guaranteed, stable, and the pass rate for filming is high. It is deeply loved by construction units. Automatic welding is also a trend, and it is gradually popularized. Welcome to consult Tianjin Yixin Pipe Equipment Co., Ltd. (lxy@yixinpipe.cn)
