1. Ultrasonic detection When an ultrasonic wave is scattered in the detected raw material, the acoustic characteristics of the raw material and the change of internal organization have a positive impact on the scattering of the ultrasonic wave. After detecting the affected level and situation of the ultrasonic wave, the function and structure of the raw material are understood.
2. Radiological detection is the use of the difference between the amount of radiation passing through the normal parts and the disadvantage and forms the resolution of blackness on the substrate.
3. Osmotic detection is to use the capillary action of liquid to penetrate the shortcomings of the surface opening of solid raw material and then absorb the permeable permeation liquid out to the surface through an imaging agent. osmosis detection is suitable for all kinds of metal and ceramic workpieces, and from infiltration manipulation to the shortcomings of the appearance time is relatively short, usually, about half an hour, and might as well to detect surface fatigue, stress erosion, and welding crack, might as well directly measure the size of the crack.
4. Magnetic powder detection is the use of shortcomings of leakage magnetic adsorption of magnetic powder, forming magnetic marks, to provide shortcomings, can detect the surface and subsurface shortcomings, shortcomings nature simple debate, paint and electroplating surface does not affect the detection vividness.
5, vortex detection main if using a ferromagnetic coil in the workpiece inductive vortex, to analyze the quality of the workpiece, can detect all kinds of conductive raw material surface and near-surface shortcomings, ordinary parameter control trouble, detection consequences are difficult to explain and require detection object must be conductive crack, and can euphemistically measure disadvantages length.
6. Magnetic leakage detection Leakage leakage detection of petroleum casing is based on the characteristics of high magnetic conductivity of ferromagnetic raw materials. After measuring the magnetic conductivity transformation caused by the shortcomings in the ferromagnetic raw materials to detect the quality of the in-the-service oil casing.
7. Magnetic impression detection is derived from the relationship between the physical nature of magnetic phenomena and the dislocation process of metals. It has many advantages such as high usage, low cost, and no polishing, and has important and ordinary use prospects in the industry.
