Description

technical field [0001] The invention belongs to ultrasonic nondestructive testing technology, and is an ultrasonic nondestructive testing method based on ART algorithm. Background technique [0002] In the fields of materials, machinery and chemicals, aluminum plates are prone to defects such as cracks and corrosion during production, processing, transportation and use. However, modern industry has very strict requirements on product quality, and small defects may cause serious threats to the environment and economy. Therefore, many countries have added non-destructive testing as a key technical link to control product quality into their own production systems. With the improvement of detection technology, the requirements of modern industry for non-destructive testing are no longer simply to determine the presence or absence of defects, but also to determine the location, size and other information of defects, which requires the combination of new technologies to complete ...
