Protection against optical and acoustic radiation during arc welding
The results of studies of the propagation of ultraviolet radiation and noise during at non-stationary arc welding workplaces
The dissertation is devoted to reduction of the harmful effects of welding fumes on the body of the welder by technological measures, in particular to improve the hygienic characteristics of alloyed electrodes. In the dissertation it is shown that the process of manual arc welding by the doped electrodes is accompanied by secretions of harmful substances such as chromium, manganese, nickel etc. It is also shown that the composition of the welding electrode, by controlling the content of alloying elements, the method of doping and coating it is possible to improve the hygienic characteristics, without losing the quality of the weld. It has been studied the influence of the type of electrode coating, the method of deoxidation-alloying of the weld metal, the type of basic metal and the composition of lithium silicate binders in the electrode coating on the secretion of the welding aerosol.
