3M Speedglas Welding Helmet

The 3M Speedglas brand is a pioneer in the field of eye and face protection for welders. The technology was originally developed in Hornfors, Sweden, in the late 1970s and early 1980s by the Swedish company Hörnell Elektrooptik AB. The brand became famous for inventing the first commercially viable auto-darkening welding filter, revolutionizing welding safety for professionals worldwide.

Today, the Speedglas brand is a core part of 3M's Personal Safety Division. While 3M is an American multinational conglomerate, the high-precision optical filters and primary manufacturing for the Speedglas line have traditionally remained centered in Sweden, where the research and specialized manufacturing expertise are located. 3M's global infrastructure ensures distribution and support across all major industrial markets.

As of 2024 and beyond, the brand is fully owned by 3M Company, headquartered in Saint Paul, Minnesota. 3M continues to invest heavily in the Speedglas line, integrating features like advanced respiratory protection and digital connectivity into their welding helmets to maintain their market-leading position.
