3M™ Speedglas™ Welding Filter

Speedglas leads the way

The innovator of the Speedglas auto-darkening welding filter completed his thesis in the shipyards of Sweden studying ways to protect welders’ eyes and skin from from harmful UV radiation.

The studies were conducted more than 30 years ago and resulted in the first prototype of an auto-darkening welding filter, a combination of liquid crystal elements, polarizers and electronics.

Today Speedglas is the world's leading brand of protective equipment for welders and it is a vital part of the 3M range of protective equipment.
