Oscar Kjellberg
Oscar Kjellberg was a Swedish inventor and industrialist. Founder of ESAB, in 1904. He invented the coated electrode used in manual metal arc welding (Patent 231733), by dipping a bare iron wire in a thick mixture of carbonates and silicates. The purpose of the coating was to protect the molten metal from oxygen and nitrogen. His pioneering of covered electrode development paved the road during the next twenty years in the research of reliable flux coated electrodes.
