The article presents results of research work enabling the environmental assessment of the arc and laser welding of corrosion resistant austenitic steel X5CrNi18-10 (1.4301). The steel, characterised by high corrosion resistance, favourable mechanical properties and good weldability enjoys popularity in many industrial sectors. The application of welding technologies in industry necessitates the performance of tests aimed to identify conditions guaranteeing safe work and protecting workers’ health. Welding and allied technologies belong to the group of processes adversely affecting a work environment. Various welding processes trigger the emission of fumes and other pollutants containing numerous substances posing health hazards. The performance of environmental assessment makes it possible to identify and analyse how a given product or technological process affect the environment. The assessment also enables the comparison of manufacturing processes and technologies in order to indicate those with the lowest environmental impact. The primary ingredients of corrosion resistant steels are chromium and/or nickel. The compounds of the aforesaid chemical elements, present in welding fumes, are rated among potentially or definitely carcinogenic substances.
