[0002] Stress detection includes stress detection on the surface of the workpiece, stress detection at a certain depth, and qualitative and quantitative analysis of stress. It is often used in quality inspection during product production, and process improvement based on stress distribution. The stresses involved include machining stress, casting stress, welding stress, 3D printing stress, cold working stress, etc. Stress detection is generally a technical means of using detection instruments to detect stress changes in stressed steel structures for technicians to compare with control values ​​to ensure construction safety, and can also be used to check whether the construction process is reasonable.
