Comparative Analysis of Hygiene and Sanitary Characteristics of Consumable Electrode Gas-Shielded Welding

Abstract:

Experimental research has been carried out to determine quantitative content of solid and gas component of welding aerosol in mechanized gas-shielded welding with constant and pulsewise electrode wire supply. As a result, it has been established that the pulsewise electrode wire supply reduces the release of harmful components of welding aerosol (welding dust СО and SiO₂) by 20-25% thanks to lower energy characteristics (the transfer frequency of electrode metal droplets and the time of their exposure to critical temperatures at a short-circuit).
