Abstract |
This research report on the humanisation of work sets out the methodology and results of laboratory investigations to determine the optimal shape of shields (attached to helmet, or hand-held) for protection against welding gases and fumes. Results of observations of aerodynamic fume behaviour and currents (by cinematography) and gas analysis enable a better choice of shields to be made. Fume deflection was improved by 25%, and only 2% of the fumes entered the welder's breathing zone. |
