摘要： Ein Verfahren zur Fertigung eines Halbzeugs (50; 51) für einen
Supraleiterdraht,
wobei das Halbzeug (50; 51) wenigstens eine NbTi-haltige Struktur (2), insbesondere NbTi-haltige Stabstruktur, umfasst,
ist dadurch gekennzeichnet,
dass die NbTi-haltige Struktur (2) schichtweise durch selektives Laserschmelzen oder selektives Elektronenstrahlschmelzen eines Pulvers (6), das Nb und Ti enthält, gefertigt wird,
und dass bei der Fertigung zumindest einiger Schichten (5, 5a, 5b) der NbTi-haltigen Struktur (2) über die Fertigung eines für eine Materialabscheidung vorgesehenen, bestrahlten Bereichs (20) einer jeweiligen Schicht (5, 5a, 5b) ein oder mehrere Prozessparameter des selektiven Laserschmelzens oder Elektronenstrahlschmelzens in einer oder mehreren ersten Zonen (23) des bestrahlten Bereichs (20) gegenüber einer oder mehreren zweiten Zonen (24) des bestrahlten Bereichs (20) variiert werden.

摘要： Niobium or its alloy based superconducting Radio Frequency (SCRF) Cavities (DB) involving at least one laser beam welded components in the SCRF cavity welded from inside surface of the wall of cavity directed to achieving more than half the thickness to full depth penetration with minimum HAZ, minimizing distortion and shrinkage. The method ensures improved weld quality and surface finish substantially free of any weld defects. Also disclosed is the welding nozzle system (NA1NB) and welding rigs (CF) adapted to facilitate such laser welding of the Niobium or its alloy based superconducting radio Frequency (SCRF) Cavities. The invention is thus directed to enhancing productivity, ensuring consistent quality and reliability, enhanced weld penetration with minimum HAZ, smooth finish of weld joints at possible reduced costs.
