Welding and Cutting . When Gustaf Dalén demonstrated welding using acetylene and oxygen for the first time in Sweden at the Finnboda shipyard in 1902, the experts of the day were unresponsive. They found the method interesting but did not believe it would come to have an practical significance. It was not long, however, before gas welding achieved a significant breakthrough. At AGA this technology was used to produce welded buoys in 1905 and in 1906 equipment and accessories for welding and cutting were a significant products for AGA. In 1913 acetylene welding became widely accepted. Welding was very important for AGA's international expansion with local production at many locations around the world. . In 1910 AGA carried out extensive trials using steel welding wire, produced according to the Siemens-Martin process. This type of welding wire was then introduced to the market in general. Back in 1916 AGA started to provide training in gas welding at its Swedish workshops for a maximum of six pupils at a time. In 1937 when the training had been transferred to an engineering school with 36 students, AGA had taught approximately 1,500 welding students. . AGA produced everything needed for welding and cutting. In addition to the equipment itself, welding carts, goggles and other accessories, the company also manufactured oxygen, acetylene gas and plants for these products. During and after the second world war electric arc welding also achieved a breakthrough. This was due to comprehensive improvements in welding methods, apparatus and additives. AGA made a powerful contribution to this development though extensive research and laboratory work. Welding and cutting are industrial techniques which are still highly significant for AGA. Product development continues unabated. This equipment is now manufactured by Gas Control Equipment, which AGA owns jointly with ESAB, while the shielding gases and acetylene are produced and distributed by AGA.
