Sažetak

This paper presents the factors that may cause pollution of the work environment when working with the oxyacetylene flame welding process. Experiments were performed using an oven that allows the analysis of all gases resulted in the welding process, but also enables their monitoring using a video camera, and the resulting film was processed in that the frames for each second of experimentation were extracted. The materials used in the experiments were S235JR steel as the base material, and as filler materials, E70S. In order to assess the impact on the work environment of this welding process, the pollution coefficient C_P was defined based on the equation of the material balance.
