Purpose: The purpose of the research was the verification of usefulness of selected non-destructive testing methods as tool of assessement of permanent joints of elements with variable thickness and geometry. Design/methodology/approach: The research was conducted with the use of samples prepared from the components used for strengthening the car seats. The elements were made from low-density polyethylene, applying the injection technology, and then butt welded. The quality assessment was conducted with the use of selected non-destructive methods - visual, thermal imaging, shearography inspection and 3D scanning. In order to verify the quality of the welds, tensile strength tests were conducted. Findings: The research conducted will indicate, within the researched scope, the method, which allows the identification of flaws of permanent joints. Research limitations/implications: Within the frame of the work we limited ourselves to the analysis of geometry of weld performed with the application of the method of butt welding. The exact assessment of quality of the joints performed requires additional tests which take into account the properly welded comparative samples and other non-destructive methods. Practical implications: The application of non-destructive methods of quality assessment, particularly spatial scanning, allows the assessment of quality and exact dimensioning of flash both from outside (visible) and outside of the element. Originality/value: The work presents the innovative application of spatial scanning 3D for the assessment of flash geometry achieved as the result of butt welding.
