Åke Hörnell is the inventor of Auto-Darkening welding filters, an innovation that has improved the working conditions for welders around the globe. Åke patented the technology and founded a company that began to introduce products under the trade name Speedglas. After a long and successful expansion ending up as market leader, the company was acquired by 3M Group. After some years of non-compete restrictions, Åke Hörnell could not resist the temptation and challenge to reenter the welding safety business. A new star – Aketek – was born.
