Founder Bio

The foundation of ESAB was built early in the last century by an inventive engineer who sought a practical solution to a common problem.

In 1904, Oscar Kjellberg produced a heavily fluxed, or coated, electrode that substantially improved the quality of weld metal. As it melted, the flux coating vaporized and formed a gas that shielded the molten weld metal from air, thus preventing embrittling reactions from occurring as the weld metal cooled.

Lightly coated electrodes of various types had been tried before, and some of them permitted faster welding, but none of them improved the weld metal properties. Kjellberg was the first to recognize the possibilities of the heavy flux coating in preventing atmospheric contamination and is today recognized as the inventor of the coated electrode. To this day, tens of thousands of welders encounter his initials in the form of an OK on the welding consumables they use.

Since Kjellberg founded Elektriska Svetsnings-Aktiebolaget (ESAB) in Sweden in 1904, the company has led the welding industry in engineering and innovation, never losing sight of ESAB's original mission to provide its customers the highest caliber of products and services.

Today's ESAB is the result of a 1989 union of industry leaders: Alloy Rods Corporation, L-TEC Welding & Cutting Systems, All-State Welding Products, ESAB Automation and ESAB Welding Products. These companies represent more than 300 years of experience in welding consumables and equipment manufacturing, and have introduced many innovative products and processes, including stainless stick and low hydrogen electrodes, as well as submerged arc, TIG ("Heliarc") and MIG welding.

The ESAB Group, Inc. is the wholly owned subsidiary of Colfax Corporation.
