A method of testing a fusion weld for a shaft includes producing two shaft subsections, wherein the shaft subsections are symmetrical and faun a cylinder coaxially along the axis of rotation. Core regions of each shaft subsection are removed in order to produce open recesses in the cylinder within remaining tubular webs. The two shaft subsections are positioned coaxially one on top of the other, wherein the two remaining webs are mutually adjacent and the two open recesses form a hollow space. A first tubular ring seam is produced by narrow-gap arc welding and in one of the two shaft subsections a passage from outside into the hollow space is produced. Further, a quality of the first tubular ring seam within the hollow space during and/or after the welding operation is evaluated by a detection device or radiation source which is introduced through the passage into the hollow space. |
