Research output: Book/ReportReport


The welds XK010 and XK011 represent closure welds of the nuclear waste canisters that have been executed using full-scale components. XK010 is continuous, with stabile parameters made weld. On the other hand XK011 has nine test sectors where different welding parameters are applied. The weld quality was examined applying non-destructive methods i.e. ultrasonic (UT) and radiographic (RT) techniques. During the realisation the application of the non-destructive techniques and systems these were just in starting phase concerning the full-scale closure weld examinations. Therefore the results are not fully comparable with the results originating from later examinations where more developed systems are applied. The nine welds with identifications XK056 - XK064 are continuous test welds made in different phases of the welding method development program. All these welds were inspected using already rather routine inspection techniques which were applied in several other inspections of this type of welds in similar manner. The applied inspection techniques were ultrasonic (UT) and radiographic (RT) methods. The report describes briefly the applied ultrasonic and radiographic techniques and the results of the data analysis.
