In 1895, the German physicist Wilhelm R?ntgen discovered X-rays, which is considered a major discovery of the 19th century. After her months of technological breakthroughs, this "new light" was used to examine broken bones and locate bullets in gunshot wounds. Although X-rays were initially used for medical purposes, the theory of the new technology was also applied to the field of non-destructive testing. Today, microfocus X-ray inspection is widely used for non-destructive testing of materials and, through continuous technological innovation, will be used in a wider range of industrial applications.
The principle of X-ray nondestructive testing is introduced:
The X-ray machine emits X-rays, which pass through the workpiece to be inspected, and then form an enlarged X-ray image on the image detector (nowadays most of them use X-Ray image intensifier). Because the internal structure of the inspected workpiece has different densities, the ability to block X-rays is not the same, so the X-ray image can clearly show the internal microstructure of the inspected sample. In short, X-rays have the ability to see through to any place where you don't want to damage the structure but want to know about internal defects.
Fully automated X-ray non-destructive testing can be used in a variety of applications. According to the customer's requirements, will be tailored to achieve "not the most expensive, but the best", in order to achieve the purpose of automated testing at the same time, as far as possible to reduce the cost of equipment, so that the cost-effective maximization.
Users only need to put forward the detection requirements, in the existing X-ray inspection technology can be involved in the scope, we can provide the most suitable multi-program for users to choose. From program design, product production, installation and commissioning, training, after-sales service, our company will provide users with value-for-money one-stop service, so that the user is clear consumption, reliable use.

Typical applications of X-ray non-destructive testing
X-ray non-destructive testing has a wide range of applications in the fields of material testing, food testing, manufacturing, electrical appliances, instrumentation, electronics, automotive parts, medicine, biology, military, archaeology, geology and so on.
Requirements of X-ray NDT that users need to provide:
Inspection target, i.e., find defects, impurities, or contactless measurement.
Resolution, i.e., detecting the smallest defect or detail size.
Contrast, i.e., to detect the density difference of the workpiece.
Inspection area, i.e. the size of the inspected part.
Inspection speed, i.e., inspection efficiency.
The degree of automation, i.e., manual resolution or machine vision.
Expected cost.
