Oscar Kjellberg (born September 21, 1870 in Arvika , † July 5, 1931 in Gothenburg ) was a Swedish engineer and inventor.

Kjellberg began his professional career as a technician in Lindholmens Verkstad - a shipyard in Gothenburg . In doing so, he developed electric welding . Lindholmens Verkstad financed the development of the invention and ESAB founded in 1904 . Electric welding quickly gained importance in shipbuilding. Before the First World War , ESAB had factories in England and Russia. Oscar Kjellberg is considered to be the inventor of the coated welding electrode . On June 27, 1908, he received the Imperial Imperial Patent 231733 "Electrode and method for electrical soldering".

To manufacture and market this invention he founded together with six other German and Swedish shareholders in 1921 in Berlin the Kjellberg electrodes GmbH . Due to a lack of suitable welding power sources, Kjellberg Elektro-Maschinen GmbH was founded in Finsterwalde in 1922 at the suggestion of Oscar Kjellberg . The first Ke 200/1450 welding generator developed and built in Finsterwalde was presented at the spring fair in Leipzig in 1923 . In the same year welding electrode production started in Finsterwalde. The oldest product is the OK G2 / 1 stick electrode , an electrode for repair welding .

After his death, Kjellberg was buried in the Ostfriedhof (Östra kyrkogården) in Gothenburg .
