Abstract

This paper presents the main factors that cause environmental pollution in the case of the welding procedure in a protective gas environment. In the research the MIG and MAG welding processes were taken into account. The materials used in the experiments were 8TiCr170 stainless steel as the base material and as filler materials 4 types of welding wires were used, characterized by different chemical compositions. To assess the impact on the work environment of such welding processes the pollution coefficient C_p was defined based on the material balance equation as the ratio of the mass of all materials used in the welding process M_t and the effective mass of the welded performed M_u.

Keywords
