title = "Narrow Gap Arc Welding Experiments of Thick Copper Sections",
abstract = "The spent fuel from Finnish nuclear reactors is planned to be encapsuled in thick-walled copper canisters and placed deep into the bedrock. The manufacturing methods of the copper canister have been widely studied and some studies are still going on. The objective of this study was to find out, if the narrow gap arc welding is suitable for the welding of thick copper sections. This report includes a literature review of arc welding of copper. Welding trials were carried out to find out if the welding procedure is suitable for the welding of thick copper sections. The welding trials required a certain development work of the welding equipment. A narrow gap TIGwelding tool including two cascade welding nozzles was developed for the study. A copper welding station, which is an insulated cell, was also developed for the welding trials",
