| Resumen |
The UV and IR components of welding arc emissions were measured and their dependence on the welding current, presence of shielding gases and composition of the metals being welded was determined. Maximum infrared emissions (3500W/m2) were 100-fold greater than ultraviolet emissions. Time studies have shown that welders can be exposed to arc radiation for as much as half of a shift, although the arc may be active for only a few seconds at a time. Although protective clothing blocks shorter-wavelength light, the absorbed energy can be reradiated at infrared wavelengths, which makes the clothing a secondary radiation source. The effects of heat build-up can be minimised by using screens as the primary means of blocking radiation from the arc, and by limiting periods of continuous exposure. Not only welders, but all persons in the vicinity of a welding arc must make use of protective equipment. |
