Modes of electron-beam local thermocycling treatment of welded joints of ∅ 88 × 4 mm pipes from alloy É125 (Zr – 2.5 % Nb) are tested. The structure of the welds is studied. The characteristics of mechanical properties are determined under tension and static and dynamic bending. The corrosion resistance is determined in long-term tests in an autoclave with water at 285 °C and in fast tests in an autoclave at 360 °C for 336 h in accordance with the International Standard.
