Metallurgical aspects of the overlay welding process
Original language description
Microstructure developed during cladding and annealing at the interface between the austenitic CrNi overlay and the ferritic-carbidic CrMoV steel for VVER reactor pressure vessel was studied. Overlay welding was carried out using an automatic submerged arc strip welding. The cladded test plates were tested ultrasonically. Metallographic observations through the optical, electron transmission and scanning microscopes were used. The weld overlays satisfied the conditions laid on weld overlay for power engineering. No significant variation of results between tested plates were found. The transition zone between austenitic overlay and base metal is complicated. A carbidic dark interlayer the with of which increases with temperature and annealing time is formed on the fusion line during weld overlay stress-relieving. No microcracks or disbonding have been observed in materials tested.
