The factors that affect the accuracy of weld detection by flaw detectors include the detection object, temperature, surface roughness, magnetic field, attached substances, shape characteristics of defects, acoustic impedance of defects, and surface characteristics of defects (such as smoothness).　

X-rays are generated by high-speed moving electrons interacting with matter. In an X-ray tube, electrons emitted from the cathode are accelerated by the electric field between the cathode and anode, and then bombard the X-ray tube target, transferring their kinetic energy to the atoms on the target.　

The flaw detector mainly introduces the most commonly used method of obtaining internal characteristic information of objects through reflection. The reflection method is based on the principle that ultrasound undergoes strong reflection when passing through interfaces with different acoustic impedances　

One Angle probe: a probe used for oblique beam testing, mainly for transverse wave testing. The oblique probe is composed of oblique blocks, piezoelectric chips, sound-absorbing materials, shells, sockets, etc. The sound beam of the oblique probe is inclined to the surface of the probe, so it can be used to detect parts that cannot be reached by the straight sound beam, or areas where there is an angle between the direction of defects and the detection surface.　

Hamamatsu flat panel detector is a precision and valuable equipment that plays a decisive role in imaging quality. Familiarity with the performance indicators of the detector can help improve imaging quality and reduce X-ray radiation dose.　

其实保险丝的种类特别多，但是成品的保险丝外观是检测不出什么缺陷的，需要通过X射线观察内部来判断是否存在缺陷。小编就“Xray检测机可以用来检测保险丝的内部缺陷吗”为主题，来聊聊Xray检测机的应用，快来跟小编一起一睹为快吧。　

判断滨松平板探测器图像质量的好坏，通常用调制传递函数(MTF)和量子转换效率(DQE)来衡量。MTF和DQE值高则表明该平板探测器产生的图像质量能够达到较好的空间分辨率和密度分辨率。　

The echo height of the flaw detector is relatively high, the amplitude is wide, and there may be multiple peaks. When the probe moves, the reflected wave continuously changes in amplitude, and when the probe rotates, the peak of the wave moves up and down. Cracks are a highly dangerous defect that not only reduces the strength of welded joints, but also causes stress concentration and becomes the origin of structural fracture due to the sharp notch at the end of the crack.　

1、 Storage: After using the flaw detector, the surface should be cleaned and placed in a dry and ventilated room. It should not be stored in direct sunlight or in contact with rainwater, oil stains, corrosive gases, etc., and should avoid strong vibration and compression. Do not distort or apply heavy pressure at the connection of the probe. When unplugging or inserting wires, grasp the root of the plug.　

Industrial CT stands for Industrial Computer Tomography Technology. It can display the internal structure and composition of the inspected object clearly, accurately, and directly in the form of two-dimensional tomographic images or three-dimensional images without damaging the inspected object. Materials and defects are known as the best non-destructive testing techniques today.　

1. The greater the applied external magnetic field strength, the greater the induced magnetic field strength in the workpiece, the denser the distribution of magnetic lines, and the greater the strength and quantity of magnetic line bending obstructed by defects, resulting in an increase in the strength of the leakage magnetic field formed.　

In the process of automated production of industrial equipment, it is necessary to judge the quality of products. Traditional manual visual judgment has low efficiency, and the accuracy of quality judgment is often affected by visual ghosting and lighting issues during the judgment process　

The Keysight i7090 online testing system has the capabilities of ICT, power on, programming, and functional testing. It supports 20 cores for simultaneous testing, 160 programming channels for simultaneous programming of the tested product, and 16 sets of programmable power supplies. It also supports Keysight or third-party PXI interface instruments for functional testing,　

Users who are using the flaw detector for the first time may not be familiar with the settings and selection of the instrument's straight probe and oblique probe. Here is a brief introduction to the differences in probe settings for users: 1. Straight probe: 1 Instrument settings: (1) Basic main menu ① Limitations: Determine based on the thickness of the workpiece ② Sound velocity is 5920 meters per second (2) Angle probe main menu ① Probe angle is "0"　

AXI (Automated X-Ray Inspection) is a type of optical inspection system used for automated X-ray testing. AXI is a relatively mature testing technology. After the assembled circuit board (PCBA) enters the machine along the guide rail, there is an X-Ray emitter tube located above the PCB,　

Today, the editor will talk to you about what to pay attention to when charging a flaw detector? 1. Please make sure to use a dedicated power adapter to charge the battery. If using a non local charger to charge the flaw detector causes problems, it is not covered by the warranty.　

As soon as you hear the name "flaw detector", you will know that it detects objects through a type of sound wave. As for what it detects, many people may not be familiar with it. Since ultrasonic waves are used for measurement, it is inevitable that other factors may cause inaccurate measurement values,　

The flaw detector is mainly used to detect whether there are defects (cracks, sand holes, pores, white spots, inclusions, etc.) inside the machined parts, whether the welds are qualified, and to search for hidden injuries, in order to determine whether the workpiece is qualified or not. Flaw detectors are generally used for non-destructive testing. Industrial sectors such as shipbuilding, petroleum, chemical, mechanical, aerospace, transportation, and construction inspect materials such as ship hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles, and bridges　

Nowadays, flaw detectors usually emit ultrasound to the object being tested (such as industrial materials, human body), and then use its reflection, Doppler effect, transmission, etc. to obtain information inside the object and process it to form an image.
