The workpieces were lain out before cutting in such a way as to maintain minimum requirements regarding sample dimensions for each test. All joints provided for tests were lap joints. Each joint was visually examined before cutting. The study results for all analysed joints in this article were positive and met the criteria presented in the DIN 6700-5 standards6. In order to make this paper clearer and due to the high number of samples and tests, it was decided that all obtained results be presented in the form of minimum and maximum value ranges obtained from each test.
