Welding technology

Representative set of weldments was examined site welds (with pearlitic type weld metal) and two types of site weld repair zones with different welding technologies using Cr-Ni filler metals and Ni-based alloy. Results of AUGUR 4.2 inspection were compared with manual ultrasonic inspection ones in terms of defect detection, characterization, positioning and sizing in order to estimate correlation between these data.

Cryolite is utilized in the manufacture of aluminum, in the processing of aluminum waste (as a flux in the electrochemical removal of magnesium), as a flux in the aluminization of steel and in welding technology, in the manufacture of glass and enamel, as an additive in the manufacture of abrasives and as an auxiliary product in the remelting of light metals.

The BR-5/10 reactor pump level indicators sensors are made of stainless steel tube 20 mm in diameter and with wall thickness of 0.2 mm. They are divided into sections to which current collectors are welded. Leaks took place through cracks formed in joint welds of these sections. After improving the joint welding technology of current collectors there were no cases of level indicating sensors. On the rest of the reactors the level indicators of other design are used. No leaks due to such cause occurred.

Sodium level indicator sensors in the pumps of the BR-5/BR-10 reactor are made of 20 mm diameter stainless steel tube having 0.2 mm wall thickness. These tubes consist of sections with welded current collectors. Leaks occurred through the cracks in the welds of the sections. After welding technology was modified, no leaks in the level indicator sensors took place. 

Technological procedures in the manufacturing of electrodes and other components and the assembly of batteries are carried out in special dry rooms or in sealed glove boxes in the atmosphere of pure argon. Assembly of batteries involves complex state-of-the-art welding technologies, complex designs of sealed tabs, and so on.
