Two non-destructive methods were applied to examine the
quality of experimental test welds of disposal canisters.
Each weld had nine sectors where different weld
parameters had been applied and start-end sector where
the welding had started and stopped. Altogether seven
welds were scanned and data acquired with ultrasonic and
radiographic methods. The ultrasonic method utilised a
128 elements linear phased array probe that was applied
with 0° and ± 20° beam angles. The radiographic method
applied a 9MeV linear accelerator and a digital detector
with pixel size of 0.4 x 0.4 mm.
The data was analysed applying the given rules to define
the so called good and optimal section in each of the
nine weld test sectors (runs). Also a large number of
individual defect indications were analysed and sized.
The results are presented in the tables of this report. A
considerable amount of figures to show the overall
quality of the welds and the placement of the defined
sectors were printed. Also the details of the numerous
indications were captured in figures and presented in the
appendixes of the report.
