Measurements of the ultraviolet radiation from gas tungsten arc welding (GTAW) and gas metal spray arc welding (GMAW) of various alloys of aluminum and magnesium were made using a microcomputer controlled rapid scan spectroradiometer. Low concentrations of magnesium in aluminum were found to yield radiation of considerably greater biological activity than non-magnesium alloys and, at a distance of one meter from the arc, up to a thousand times that of sunlight at the earth's surface. The use of… CONTINUE READING
