Arc welding is commonly applied in industry. Assessment of the quality of welded joints is one of crucial tasks especially in automated applications. In the paper preliminary research devoted to the evaluation of Heat Affected Zone (HAZ) properties using method of tracking of defined Region of Interest (ROI) on infrared images continuously acquired during welding process. The proposed method can be useful to detection of welding instabilities as well as welded joint defects.
