Abstract
Results of analysis of workers protection from ultraviolet radiation generated by welding arc are given. It is shown that intensity of ultraviolet radiation in coated electrode manual arc welding and mechanized gas-shielded welding can many times exceed the admissible norms at the distance of several tens of meters from the welding site. Thus, hazardous radiation can affect the support personnel who are in the area, and, usually, have no individual protection means, other workers, as well as random people who happened to be (pass by) at an unsafe distance from nonstationary workplaces for arc welding. Proceeding from the obtained results, a pilot sample of a mobile protective screen for nonstationary workplaces of welders has been developed and produced. Results of development and testing of the proposed mobile protective screen are given. 6 Ref., 1 Table, 7 Figures.
