Comparative assessment of selected welding imperfections in VT, PT and MT methods
Ryszard Krawczyk, Piotr Wojtas, Karolina Poch
The issues connected with assessment of sensitivity in selected NDT methods are considered. In particular, the attention has been paid to the tests which make it possible to detect any imperfection of surface, i.e. visual testing, liquid-penetrant and magnetic-powder method. The aim of the studies was to reveal the analogy and differences between results obtained from series of tests (VT, PT and MT).
