NDT Evaluation of Xk026 - Xk029 and Xk042- Xk043 EB Welds

Two non-de­struc­tive meth­ods were ap­plied to ex­am­ine the qual­ity of ex­per­i­men­tal test welds of dis­posal can­is­ters. All stud­ied welds have been man­u­fac­tured us­ing same weld­ing pa­ra­me­ters. Weld­ing were car­ried out by us­ing same weld­ing pro­ce­dures as in EB-weld Demo Pro­ject. Al­to­gether six 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 us­ing nor­mal ul­tra­sonic and ra­di­ographic in­spec­tion pro­ce­dures. Some de­fect in­di­ca­tions were de­tected, 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 in­di­ca­tions were cap­tured in fig­ures and pre­sented in the ap­pen­dixes of the re­port.
