Utraviolet Radiation Emitted by CO_2 Arc Welding

摘要

The arcs associated with arc welding emit high levels of ultraviolet radiation(UVR), and this often causes acute injuries in the workplace, particularly photokeratoconjunctivitis. It is important to know the level of UVR emitted by arc welding under various conditions, as this information will help in evaluating potential UVR hazards in welding workplaces and taking protective measures against it.
