Quality assurance of aluminium weld seams and cast casings of the W7-X coils

The WENDELSTEIN 7-X stellarator is the next step device in the stellarator line of IPP Garching. It is presently being assembled in the branch institute of IPP at Greifswald. The central part of W7-X is the superconducting magnet system. It comprises 50 non-planar and 20 planar coils. This contribut...

Description
Summary:The WENDELSTEIN 7-X stellarator is the next step device in the stellarator line of IPP Garching. It is presently being assembled in the branch institute of IPP at Greifswald. The central part of W7-X is the superconducting magnet system. It comprises 50 non-planar and 20 planar coils. This contribution outlines for two critical examples of the magnet system the quality assurance measures applied, namely for the aluminium weld seams at the superconductor cable during the assembly and for the cast steel casings of the non-planar coils during manufacture.
