| Popis: | The decrease in the fume formation rate at the transition from globular to spray mode during welding has been investigated. A physical model describing this phenomenon has been developed. The essence of the consideration is that the model takes into account the different heating of droplets of the liquid metal by the are plasma in the two welding modes. New experimental results have been obtained for welding of stainless steel in a shielding gas containing oxygen. The decrease of the fume formation rate estimated on the basis of the model is in agreement with experimental data obtained and in the literature. |
