Welding Back Glass

Welding black glass is a type of welding that uses a black glass filter to reduce the amount of ultraviolet (UV) and infrared (IR) radiation emitted during the welding process. This helps to protect the welder's eyes and skin from harmful radiation and improves visibility of the weld puddle.

Welding black glass is typically used in TIG welding, also known as Gas Tungsten Arc Welding (GTAW), which is a type of welding that uses a non-consumable tungsten electrode to produce an arc. The black glass filter is placed over the lens of the welding helmet and absorbs the UV and IR radiation, making the weld puddle appear darker and easier to see.

Welding black glass filters come in different shades, typically #8, #9, and #10. The higher the number, the darker the filter is, and the more radiation it absorbs. The choice of the shade depends on the type of welding, the material being welded, and the welder's preference.

It's important to note that welding black glass filters don't protect from the intense light produced during the welding process, it is important to use a welding helmet that meets the necessary safety standards.
