| Abstract Scope |
SKB has chosen FSW to seal the 6000 copper canisters that will contain Sweden´s nuclear waste. This paper shows the major challenges as production is starting, including repeatable probe manufacturing and control and measurement of the shoulder depth using a newly installed laser sensor. By controlling the shoulder depth the possible hook discontinuity in the capture joint can be controlled. For the probe manufacturing the challenges include achieving the same surface roughness as it affects the process window for cavity formation. |
