无损检测(Non-destructive testing 简称NDT)，一般包括以下几种: 1、射线检测（Radiography Testing，简称RT） 2、超声波检测（Ultrasonic Testing，简称UT） 3、磁粉检测（Magnetic Testing，简称MT） 4、渗透检测（Penetrant Testing，简称PT） 5、涡流检测（Eddy current Testing，简称ET）

Radiographic testing (RT) is a non-destructive testing (NDT) method widely used to assess the integrity of materials and structures without causing damage. This technique plays a critical role in industries such as welding, aerospace, automotive, manufacturing, pipelines, and construction, ensuring safety and quality through precise evaluations.

Radiography testing (RT) is one of the most widely used non-destructive test (NDT) methods. With the help of this method, we can detect hidden flaws or discontinuities present in welds such as cracks, porosity & blowholes, slag, flux or oxide inclusions, lack of fusion, incomplete penetration, Mismatch, and tungsten inclusion, etc.

Discover the advantages of the radiographic testing (RT) method, understand the basic principles of RT, and explore the variety of techniques for applying this highly adaptable method in nondestructive testing across industries.

RT： radiographic testing 射线检验 . UT： ultrasonic testing 超声波检验 . MT：maganetic particle testing 磁粉探伤. 三者都属于 nondestryctive testing（NDT）无损探伤的一种。 RT/UT检查内部缺陷，MT检查表面。 三者特点： 射线对气孔和夹渣比较明显。 超声波对裂纹比较敏感。

2023年10月28日 · 无损检测(ndt)是一种利用先进的技术和设备，在不破坏被检测物体的内、外表面的结构、性能和状态，从而评价其连续性、完整性和安全性的技术。 无损检测技术广泛应用于我国经济建设的各个领域，在保证产品质量和安全方面发挥着重要作用。

Radiographic Testing (RT or X-ray or Gamma ray) is a non-destructive testing (NDT) method that examines the volume of a specimen. Radiography (X-ray) uses X-rays and gamma-rays to produce a radiograph of a specimen, showing any changes in thickness, defects (internal and external), and assembly details to ensure optimum quality in your operation.

Radiographic testing (RT) is a non-destructive testing (NDT) method which uses either X-rays or gamma rays to examine the internal structure of manufactured components, identifying any flaws or defects. In radiography testing the test-part is placed between the radiation source and film (or …

RT can be used to detect internal discontinuities in almost any material that is not too thick. X-ray machines capable of penetrating as much as 660 mm (26 in.) of steel and greater thickness of other materials are available. RT can disclose internal structures, configurations, fluid levels, and fabrication or assembly errors.

Radiographic Testing (RT) is a powerful and reliable NDT method that enables accurate detection of internal defects in materials and welded structures. Despite its safety concerns and high costs, its ability to produce detailed, high-resolution images makes it indispensable for quality control and safety assessments in industries such as oil ...
