Both surface and volume methods of non-destructive testing can be used for plastic welds. Non-destructive testing of plastics has certain limitations. The limitations are related to the physical-mechanical properties of the material, as well as the geometry of the tested parts. The most common inspection of welds on plastic materials is a visual inspection, which is carried out to the extent of 100 %. For the inspection of plastic welds, it is also possible to use the penetration method and, with limitations, also ultrasonic and radiographic inspection.skhttp://creativecommons.org/licenses/by/4.0/non-destructive testingplastic materialsweldingjointsArticlehttps://doi.org/10.26552/tech.C.2024.1.11
