Description
technical field [0001] The invention belongs to the technical field of mobile scanning flaw detection monitoring and detection of metal materials, and in particular relates to a novel magnetic memory mobile scanning sound and light alarm system. Background technique [0002] With the development of modern productivity, metals have been applied to various fields of our lives, but the economic losses caused by metal damage are also increasing year by year. However, the general non-destructive testing technology can only detect the cracks or defects that have been formed, but cannot detect the fatigue damage caused by stress concentration in an early stage. The principle of metal magnetic memory is that ferromagnetic materials form magnetic and elastic interaction energy under the action of stress, reorienting the magnetization, resulting in changes in the magnetic field strength to achieve the purpose of measurement, so early detection of metal materials can be carried out. H...
