Sažetak
Temperature field is of crucial importance for the understanding of heat effects on welding and weld defects. The temperature distribution determines the microstructure in the heat- affected zone as well as residual stresses and distortions of the welding construction. An infrared camera provides a twodimensional image of the infrared emission, at the surface of the sample, from which isothermal lines and the temperature distribution can be captured. Comparison of analytical and experimental solution of temperature field in metal thin- walled sheet around the moving heat source is presented in the paper. In the experiment, temperature field is recorded using thermographic camera Vario Cam 640 Hi Res in a way that camera was moving together with a heat source so the temperature field is regarded as 2D quasi-steady. Analytical solutions for the moving line source on the thin-walled sheet and moving point source on the flat layer are computed using software Engineering Equation Solver. The isotherms from the thermograms and analytical solutions are shown in 2D diagrams and compared. It is concluded that the infrared thermography can be practical weld-monitoring option able to provide a reliable estimation.
