The present invention relates to a method for generating a tool path (20; 82) for an application tool (12) for additive manufacturing, in particular for additive manufacturing using buildup welding, of a substantially rotationally symmetric workpiece (28; 328), comprising the following steps: a) providing cross-sectional contour data describing at least a portion of a cross-sectional contour (42; 342; 442; 542) of the workpiece (28; 328); b) providing axis data describing a rotation axis (R) of the rotationally symmetric workpiece (28; 328); c) generating a continuous cross-sectional path (54; 354; 355; 454; 554), taking into account the cross-sectional contour data, the cross-sectional path (54; 354; 355; 454; 554) being inscribed in the portion of the cross-sectional contour (42; 342; 442; 542); d) generating the tool path (20; 82) with a helical or/and spiral course revolving around the rotation axis (R), wherein the tool path (20; 82) intersects the cross-sectional path (54; 354; 355; 454; 554), preferably with each revolution around the rotation axis (R).
