Weld seam inspection is an essential work in various fields such as engineering construction, aerospace, and nuclear energy. In weld seam inspection and testing, there are different inspection levels and standards according to different industries and project requirements, including Level 1, Level 2, and Level 3 standards. To help everyone gain a deeper understanding, the following content is organized by Chuangxin Testing Network and provided for your reference.

First level standard:

The first level standard is generally applicable to engineering projects with lower importance. In the first level standard, the quality requirements for weld seam inspection are relatively low, and the sensitivity and accuracy requirements for inspection are not particularly high. This standard is usually applicable to some less important equipment and engineering, such as certain building structures, steel products, etc.

Secondary standard:

The secondary standard is applicable to some important engineering projects, such as aviation, aerospace, nuclear energy, military and other fields. In the second level standard, the quality requirements for weld seam detection are higher, and the sensitivity and accuracy requirements for detection are also higher. This standard is usually applicable to some important equipment and engineering, such as airplanes, nuclear power plants, etc.

Third level standard:

The third level standard is applicable to the most important engineering projects, such as nuclear submarines, satellites, missiles, etc. In the third level standards, the quality requirements for weld seam inspection and testing are very high, and the sensitivity and accuracy requirements for testing are higher. This standard is usually applicable to some very important equipment and projects, such as nuclear reactors, missile launchers, etc.

The first, second, and third level standards for weld seam inspection depend on different engineering projects and industry needs. According to different standards, the quality requirements, sensitivity, and accuracy of weld seam inspection and testing are also different. Therefore, when conducting weld inspection and testing, it is necessary to determine the testing standards based on the specific project requirements, and ensure the accuracy and reliability of the testing process to ensure the safety and stability of the engineering project.
