2. Welding helmet - Wikipedia

   en.wikipedia.org/wiki/Welding_helmet

   Speedglas welding helmet. The modern welding helmet used today was first introduced in 1937 by Willson Products. [5] In 1981, Swedish manufacturer Hornell International (now owned by 3M [6]) introduced an LCD electronic shutter that darkens automatically when sensors detect the bright welding arc, [7] the Speedglas Auto-Darkening Filter. With ...

   Blunt force trauma can occur to the eye when excessive force comes into contact with the eye. Chemical burns, biological agents, and thermal agents, from sources such as welding torches and UV light, also contribute to occupational eye injury. [14] While the required eye protection varies by occupation, the safety provided can be generalized.

6. Shielding gas - Wikipedia

   en.wikipedia.org/wiki/Shielding_gas

   These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or active shield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals. Most of these gases, in large quantities, would ...

7. Welding Procedure Specification - Wikipedia
