DR detection process analysis for weld of pressure-bearing special equipment

Due to the complex and harsh operating environment of pressure-bearing special equipment, the occurrence of accidents is very harmful, so its safety performance is very important. At present, the smelting and machining technology of related raw materials and components is very mature, but the toughness of the weld metal generally lags behind that of the base metal, which has become the weakest link in pressure-bearing special equipment. Especially in long-term operation under complex working conditions such as high temperature, high pressure, and vibration, it is easy to produce fatigue, corrosion defects, or cause the expansion of residual defects in manufacturing and installation. This paper will analyze and introduce the digital ray (DR) detection process of weld of pressure-bearing special equipment, and provide a certain reference for the correct use of digital ray technology.
