The work presents the results of studying harmful substances in the air, released during nonconsumable electrode argon-arc welding of 1201 (Al–Cu–Mn) and 1460 (Al–Cu–Li) aluminium alloys. The objective of this work is performance of sanitary-hygienic assessment of the nature of aerosol and gas evolution from these alloys, in order to ensure favourable sanitary-hygienic working conditions for welders. It is shown that for 1460 alloy with lithium the intensity of welding aerosol formation is 1.5 times higher, and ozone concentration exceeds the maximum admissible concentration 3–4 times in the same welding modes. 13 Ref., 4 Tables, 5 Figures.
