Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0023] refer to figure 1 , a method for detecting residual stress of aluminum products, comprising the following steps:
[0024] S1: Cut the sample, cut and sample at both ends and the middle part of the tested sample;
[0025] S2: Appearance inspection of the sample. When in use, the laser level detection device detects the level of the sample, and at the same time records the weight of the sample separately;
[0026] S3: Sample number, different samples are numbered differently and stored in the same location;
[0027] S4: Ultrasonic testing, place the sample to be tested together with the ultrasonic testing equipment in a vacuum box, and perform residual stress ...
