Kjellberg Finsterwalde is a group of German companies in the metal and electrical industry. The group consists of the three manufacturing companies, Kjellberg Finsterwalde Plasma und Maschinen GmbH, Kjellberg Finsterwalde Schweißtechnik und Verschleißschutzsysteme GmbH and Kjellberg Finsterwalde Elektroden und Zusatzwerkstoffe GmbH, and the Kjellberg Finsterwalde Dienstleistungsgesellschaft mbH, which fulfils group-wide functions. Sole shareholder of the group is the Kjellberg Foundation, with its registered seat in the Hessian city of Gießen. The group manufactures products for thermal metal working (welding, plasma cutting). Approximately 280 employees at the three locations in Finsterwalde, Massen and Witten achieved annual sales of about € 47 million in 2008, with international sales accounting for more than half of this amount. The group holds a share of equity in a Slovak company and has a network of partners worldwide. Kjellberg Finsterwalde manufactures plasma cutting technology (up to 600 A), automatic welding machines and welding electrodes for industrial purposes, with part of the products customised. For example, Kjellberg equipment is used in the shipbuilding, automotive and plant construction industries. == Early history == On 27 June 1908, the Swede Oscar Kjellberg received German Imperial patent no. 231733 "Electrode and procedure for electrical soldering" and is therefore recognised as the inventor of the coated welding electrode.〔(German Imperial patent no. 231733 held by Oscar Kjellberg ) (pdf) 〕 In his capacity as general manager of the company ESAB, in 1921 Kjellberg established Kjellberg Elektroden GmbH in Berlin together with six German and Swedish partners, for the purpose of manufacturing and marketing the patented welding electrodes. For lack of suitable power sources and at Oscar Kjellberg’s suggestion, Kjellberg Elektro-Maschinen GmbH was established in Finsterwalde in 1922. In 1923, the company's first welding generator developed and built in Finsterwalde, Ke 200/1450, was presented at the Leipzig spring fair. Later that year, the production of welding electrodes started in Finsterwalde. The oldest product was the rod electrode OK G2/1, which was used for repair welding. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kjellberg Finsterwalde」の詳細全文を読む スポンサード リンク
