Popis: This paper presents experimental results of comparative tensile tests of butt welded joints (P295GH) by the use of thermography and standard methods. During tensile testing the deformation of base and weld material is occurring. The occurrence of plastic deformation is accompanied by the temperature increase in the zone where plastic deformation is present. Test specimens were tested on electro mechanical tensile testing machine with the application of the control strain. These tests have shown the potentiality for the application of non-contact thermography during deformation of the material where the possibility for the estimation of stress conditions and prediction damage in welded structures and materials exists.
