RT pass rate is ninety percent.
The average passing rate of RT (ray detection) is 97.24%, among which the passing rate of welding of the first group of fully automated welding units is as high as 99.02%. Welding pass rate in the middle section of the Russian-Chinese Eastern Route in ten sections has always been exclusive, is deservedly the whole line of welding quality champion.
In the late stage of attack, the sixth section of the complex terrain, through the project, leaving the head as many as 103. Connoisseurs know that the head operation is limited by the space and process, can not utilize too much personnel and equipment.
Application:
Ray inspection is one of the early application of material testing methods. 1896, that is, the German physicist R?ntgen Χ-ray discovery of the second year, the British Hall Edwards and Radcliffe X-rays used for medical diagnosis; soon after he will be used to check the defects of the metal X-rays.
Gamma-ray inspection began in 1925, when Pilon and Laborde used radium to conduct radiographic inspections of steam engines. 1948, due to the emergence of artificial radioisotopes, the application of gamma-ray inspection is becoming more and more widespread.
Ray inspection in industry has a very wide range of applications, it is used for both metal and non-metal inspection. The defects that may arise within the metal, such as porosity, inclusions, loose, cracks, unwelded and unfused, etc., can be inspected with rays. The industries where it is applied are pressurized equipment, aerospace, ships, weaponry, hydraulic sets and bridge steel structures.
