Welding mask is a type of headgear used when performing certain types of welding to protect the eyes, faceandneck from flash burn, ultraviolet light, sparks, infrared light, and heat.
masks are most commonly used with arc welding processes such as
shielded metal arc welding, gas tungsten arc welding, and gas metal arc
welding. They are necessary to prevent arc eye, a painful condition
where the cornea is inflamed. welding masks can also prevent retina
burns, which can lead to a loss of vision. Both conditions are caused by
unprotected exposure to the highly concentrated ultraviolet and
infrared rays emitted by the welding arc. Ultraviolet emissions from the
welding arc can also damage uncovered skin, causing a sunburn-like
condition in a relatively short period of welding.
