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.
