Abstract
Results of investigation of hygienic characteristics of fumes formed in covered-electrode welding of high-alloy chromiumnickel steels are presented. It is shown that they are determined by the content of alloying elements in electrode rod and covering, type of electrode covering, method of deoxidising-alloying of the weld metal, and composition of a gas-slag forming base of coverings. The level of emissions and toxicity of welding fumes can be decreased by changing the above factors.
Keywords: arc welding, high-alloy steels, covered electrodes, welding fumes, chemical composition, toxicity
