Method for non-destructive testing by means active thermography, of parallel and overlap welded joints, preferably by laser method without melting through

摘要

method of non-destructive testing method termografii active joints welded, parallel and zaku0142adkowych, is that it uses an unidentified heat flow that makes by heating the test sample, preferably by means of infrared.depending on the thickness of the plates tested positive warm-up time is from 0.1 to 60 seconds for sheet thickness from 0.5 to 5 mm, and the distance of the heat source from the test sample, preferably from 1 to 1000 mm, depending on the efficiency of heating the heat source.then recorded the temperature or the temperature changes in the time on the surface opposite to the surface of the sample, nagrzewanej through favourable thermal cameras, and the results obtained on temperature changes during the analyses and interprets the designation and evaluation the contrast on the surface opposite to nagrzewanej temperature samples.
