title: A field study of near ultraviolet welding irradiance.
abstract: Spectral irradiance in the near U.V. was measured for several welding operations at a large steel fabrication shop. The variations of spectral irradiance with time were measured and a brief study of the effects of amperage welding rod, and distance was performed. At the measurement distance used in this study the proposed standard for near U.V. was not exceeded.
