| titleOfInvention | Penetrant flaw detection process |
| abstract | The invention provides a penetration flaw detection process, which comprises the following steps: s1 pretreatment: cleaning the surface and the vicinity to be detected, removing the surface and the like; s2 penetration: preheating the welded test piece to a certain temperature, spraying a penetrating agent on the surface of the test piece, and penetrating for a period of time; s3 emulsification: coating an emulsifier on the detected surface of the test piece; s4 cleaning: washing off the penetrant on the surface of the test piece by water; s5 developing: spraying or coating the developer on the surface of the test piece, wherein the surface is provided with an obvious color display trace; s6 Observation: for the coloring method, the direct observation is carried out by naked eyes, and the observation is carried out on the tiny defects by means of a magnifying lens with the magnification of 3-10 times. The invention provides a process for carrying out penetrant flaw detection by using a novel penetrant flaw detection agent, which has high flaw detection efficiency, simple operation, no damage to products and high sensitivity. |
