Emission of airborne ultrafine particles during welding of steel plates
Ciencia e Tecnologia dos Materiais
The present study is focused on the characterization of ultrafine particles emitted in welding of steel using mixtures of Ar+CO2, and intends to analyze which are the main process parameters which may have influence on the emission itself. It was found that the amount of emitted ultrafine particles (measured by particle number and alveolar deposited surface area) are clearly dependent from the distance to the welding front and also from the main welding parameters, namely the current intensitydoi:10.1016/j.ctmat.2014.09.001 fatcat:3jlz36g2lrc55bwmncq6s5srri
