Hard requirements for the quality of electrodes delivering to NPP

Requirements for the quality of electrodes, used during argon-welding of NPP pipelines and equipment are considered. To improve the quality of welded joints it is recommended to deliver electrodes of not lower, than the 2d group (according to AU SS) with obligatory testing at manifacturer their welding technological properties by re-welding pipe samples and radiographic monitoring of weld uniformity, as well as to increase the requirements for the quality of electrode package
