Any welding process is perceived to be a radiation hazard to the eye.
Site visits were made to an automotive assembly plant to assess the levels of optical radiation and other hazards on the production line.
Measurements were taken with a scanning spectroradiometer and optical power and energy meters at operating working distances at spot welding stations where nonrobotic procedures were performed.
Ultraviolet (UV) irradiance levels produced while spot welding with electrodes operating at 10 to 15 kA and 10 to 20 V were several orders of magnitude below recommended safety limits for industrial exposure.
Flashes were rich in visible light and infrared (IR) radiation, but not at hazardous levels.
The principal hazards in manual spot welding with high-current electrodes are high-speed droplets of molten metal produced by the process.
These are easily defended against by wraparound polycarbonate eye shields.
