摘要：
FIELD: defectoscopy.SUBSTANCE: group of inventions relates to the field of nondestructive testing and can be used to identify defects close to the defects in the controlled object surface. Thermographic method for controlling products has been announced, which contains the following steps: heating the site of the monitored object with the creation of an unsteady temperature field, recording the controlled product surface degree of heating, by measuring the defective area IR radiation value in comparison to the defect-free environment heating degree; positioning the of the defective area position and its dimensions and determining the defect permissibility when using the product; locally load the area with signs of defectiveness, and then carrying out thermographic inspection, determining by the difference of thermographic images before and after loading the propensity of defects to development under the action of a local load; synchronize the speed of moving the product with the speed of shooting the thermal
