Understanding Welders Glass

Definition and Purpose

Welders glass, also known as a welding filter, is a critical safety component designed for eye protection in welding applications. Its primary function is to shield a welder’s eyes from the intense light, ultraviolet (UV), and infrared (IR) radiation produced during welding operations. By filtering out harmful rays, it prevents damage to the eyes which can occur from exposure to the bright arc light and radiation (OSHA Factsheet).

Materials and Composition

The primary material used in the construction of welders glass is borosilicate, a type of glass celebrated for its resistance to thermal shock and its ability to withstand extremely high temperatures without losing integrity. This durability is crucial in welding environments where temperatures can soar and the risk of glass shattering can pose serious safety risks (Safety Glasses USA).

Welders glass is treated with special coatings that afford it the capability to block UV and IR rays effectively. These coatings are integral to the glass’s protective properties, ensuring that only a fraction of the harmful light reaches the eyes. The glass itself comes in a variety of shades, each suited to a particular level of exposure to light and radiation. The shades range from Shade 1.5, which allows more light to pass through, to Shade 14, which is the darkest and offers the highest level of protection (Phillips Safety).
