TL;DR: In this paper, the influence of welding parameters on the tensile strength and fracture of Ni-base superalloy joints was analyzed and it was found that the root of welding joint is unwelded when the welding current is lower, so that the strength and elongation of welded joint are inferior.

TL;DR: In this article, a new mathematical description of a heat-source has been formed to represent the common in-service welding process, i.e. vertical-up and vertical-down manual metal arc (MMA) welding with hydrogen controlled electrodes.

TL;DR: In this article, the shoulder geometry was identified that produced the most stable weld cycle, then the welding parameters were optimised for that geometry with regards to stability, and finally, the chosen geometry and welding parameters are verified and evaluated during multiple weld cycles.
Abstract: The spent nuclear fuel from Swedish power plants will be placed in copper canisters that are sealed with friction stir welding and the stability and robustness of this process is now being optimised in three steps: first, the shoulder geometry was identified that produced the most stable weld cycle, then the welding parameters were optimised for that geometry with regards to stability, and finally, the chosen geometry and welding parameters were verified and evaluated during multiple weld cycles. The shoulder study showed that stable welds could be produced repeatedly with a convex scroll geometry which proved more stable than various concave and flat scroll geometries. In the subsequent parameter study, not only were the most stable values for the welding parameters derived, but a clear relationship was shown between power input and tool temperature. This relationship can be used to more accurately control the process within the parameter windows, not only for this application but for other appli...
