BAIJIAN - Third party testing organization
Flaw detection (t à n sh ā Ng) refers to the detection of cracks or defects inside metal materials or components. Generally、 magnetic、 radiographic、 ultrasonic and other instruments and devices are used. The commonly used inspection methods include X-ray inspection、 ultrasonic inspection、 magnetic particle inspection、 penetration inspection、 eddy current inspection γ Radiographic testing and other methods. Non destructive testing is the use of the sound、 light、 magnetic、 and electrical properties of materials to detect the presence of defects or unevenness in the tested object without damaging or affecting its performance. It provides information on the size、 location、 nature、 and quantity of defects. Compared to destructive testing、 non-destructive testing has the following characteristics. The first is non-destructive、 as it does not compromise the performance of the tested object during testing; Secondly、 it has comprehensiveness. As the detection is non-destructive、 comprehensive detection can be performed on the tested object when necessary、 which is impossible for destructive detection; The third is full process、 and destructive testing is generally only applicable to the testing of raw materials、 such as tension、 compression、 bending、 etc. commonly used in mechanical engineering. Destructive testing is conducted on manufacturing raw materials. For finished products and goods in use、 destructive testing cannot be conducted unless they are not ready for further service、 and non-destructive testing does not damage the performance of the tested object. So、 it can not only conduct full testing on raw materials used in manufacturing、 various intermediate processes、 and even the final product、 but also on equipment in service
