# Magnetic particle detection is to magnetize (integral magnetization or local magnetization) by applying a magnetic field to the workpiece to be inspected, and a magnetic field line will escape from the surface of the workpiece at the surface and near surface defects of the workpiece to form a leakage magnetic field, which can be adsorbed by the presence of magnetic poles. The magnetic powder applied on the surface of the workpiece forms an aggregated magnetic mark, thereby showing the presence of defects. Magnetic particle testing methods are widely used to detect defects on the surface or near surface of magnetic materials. Used to detect welds, castings or forgings such as valves, pumps, compressor components, flanges, nozzles and similar equipment. To detect defects on a deeper inner surface, a radiographic or ultrasonic test is required. The #yoke is one of the commonly used tools for magnetic particle inspection. At present, ordinary yokes (external power supply and light

This is a technology developed outside for the casting

# Non-destructive testing technology does not destroy parts or materials, can be directly tested on site, and is highly efficient. At present, there are five main types of non-destructive testing: Ultrasonic Testing, Radiographic Testing, Magnetic Particle Testing, Penetrant Testing, and Eddy Testing. Current Testing). There are many types of rays, and there are three types of X-rays , gamma rays, and neutron rays that are easy to penetrate. These three types of radiation are used for non-destructive testing, where X-rays and gamma rays are widely used for defect detection in boiler and pressure vessel welds and other industrial products and structural materials, while neutron rays are used only for special occasions. The most important application of ray inspection is to probe macroscopic geometric defects (inspection) inside the test piece. Radiation detection can be divided into a number of different methods depending on the characteristics, such as the type of radiation used, th

At present, there are five main types of non-destructive testing: Ultrasonic Testing,  Radiographic Testing ,  Magnetic Particle Testing , Penetrant Testing, and Eddy Testing. Current Testing). Ultrasound is a mechanical wave with a frequency higher than 20 kHz. Frequencies commonly used in ultrasonic testing are 0.5-5 MHz. This kind of mechanical wave can propagate in the material at a certain speed and direction, and a heterogeneous interface (such as a defect or the bottom surface of the object to be tested) that has different acoustic impedance will produce reflection. This reflection phenomenon can be used for ultrasonic flaw detection. The most common one is pulse echo detection. When the pulse is detected, the voltage from the pulse oscillator is applied to the probe (detection element made of piezoelectric ceramic or quartz wafer). The emitted ul

Magnetic ---refers to the magnetic properties of metals; in practical terms, permanent magnets, electrical materials can be made from magnetic materials (metals), and magnetic materials can be used to check for cracks in magnetic metals. Electromagnetic induction ---the phenomenon that the magnetic flux through the closed loop changes, and the electromotive force is generated in the loop is called electromagnetic induction; thus the electromotive force is called induced electromotive force. If the conductor is a closed loop, there will be current flowing, and the current is called Inductive current; transformers, generators, and various inductors all work according to the principle of electromagnetic induction.

Electronic product testing  X-ray inspection technology  is a very useful detection method in the manufacture of transformers, transceivers and semiconductors. This technology can easily show defects such as debris inside the test piece and other risks, and the test results are also independent, which can effectively reduce the artificial interference factor.  In many industries, computerized X-ray imaging (DR) is relatively more efficient because image transfer or sharing (such as between the tester and the customer) obtained by this method is easier. Plastic product testing In recent years, the development and application of plastic products has become more and more extensive, and the application of custom injection molding models has become more and more popular; the injection molding method is a widely used method for producing a large number of identical components. This technique requires very tight tolerances and does not allow defects or anomalies in the sample. X-ra

Basic knowledge of  magnetic particle flaw detector 1. According to the magnetization direction of the workpiece, it can be divided into circumferential magnetization method, longitudinal magnetization method, composite magnetization method and rotating magnetization method. 2. according to the different magnetizing current can be divided into: DC magnetization method, half-wave DC magnetization method, and AC magnetization method. 3. According to the preparation of magnetic powder used in the flaw detection, it can be divided into dry powder method and wet powder method. Principle of  magnetic particle inspection Its basic principle is: when the workpiece is magnetized, if there is a defect on the surface of the workpiece, magnetic leakage occurs due to the increase of the magnetic resistance at the defect, and a local magnetic field is formed, and the magnetic powder shows the shape and position of the defect here, thereby judging the defect.

The global flat panel detectors market has been segmented by applications into security, manufacturing, construction, semiconductors and bomb disposal among others. The others applications include medical, automotive and aerospace as the major application areas. With the advent of direct digital radiography (DR) technologies in the X-ray detectors market, demand for flat panel detectors (FPDs) by healthcare institutions and professionals has risen significantly across the globe. Considerable research in the field of X-ray imaging technologies led to the development of direct digital radiography systems. The research has its roots embedded in the development of active-matrix liquid-crystal displays (AMLCDs) for their major use in laptop computers. These AMLCDs constitute an active matrix array which consists of millions of semiconductor components embedded on a substrate. An intensifying screen attached to such an array forms the foundation of flat panel X-ray detectors. These detec
