Abstract
Considered is application of automatic orbital TIG welding for production of tight butt-lock joints on absorbing elements, which are the base of absorbing inserts of spent nuclear fuel storage containers. Results of optimisation of the TIG welding technology and ranges of optimal parameters for making of such joints are presented. The commercial unit designed for welding of the lock joints on the absorbing elements and the results of its test operation are described.
