TLDR
A special study of the potential retinal hazards from direct viewing of various welding processes was conducted by the US Army Environmental Hygiene Agency as part of a cooperative effort with the American Welding Safety Committee on Safety and Health of the Project Committee on Radiation.Abstract:
A special study of the potential retinal hazards from direct viewing of various welding processes was conducted by the US Army Environmental Hygiene Agency as part of a cooperative effort with the American Welding Safety Committee on Safety and Health of the Project Committee on Radiation. It was determined that potentially hazardous levels of visible radiation were emitted by all of the welding processes that were evaluated and that recommended filter shade numbers were generally adequate. These processes included: gas tungsten arc welding, flux cored arc welding, plasma arc cutting, plasma arc welding and shielded metal arc welding.read more

Welding Safety Measures and Welding Filters
TL;DR: The welder can quickly handle numerous welding tasks under continuous quality control but manual welding will allways be needed as a complement to automatic welding.

Derivation of maximum permissive switching time for automatic welding filter based on retinal thermal and blue light exposure limits
TL;DR: In this paper , the authors derived the maximum permissive switching time based on ICNIRP guidelines for exposure to intense optical radiation and showed that the maximum switching time is inversely proportional to the exponential function of the shade number difference.
