For 100 years, ESAB has been powered by innovation and uncompromising standards - and by the will to continuosly seek new and improved ways of serving our customers. This has made ESAB a world leader in welding products and advanced cutting systems.

ESAB's foundations were laid by an inventive technician's solution to a practical problem. The inventor was Oscar Kjellberg and what he invented was the covered welding electrode.

Even today tens of thousands of welders encounter his initials in the form of an OK on the welding consumables they use. In 1904, Oscar submitted a hand written patent application, which described his unique invention.
