Abstract
A clamping tool (SW) for spatially fixing the tubular workpiece (W), preferably a clamping clamp or jaw, or a multi-segment clamping system. [0002] The present invention relates to a method for producing a stepped cross-section reduction in a one-piece tubular workpiece (W) made of metal, wherein a forming area (U) of the workpiece (W) is formed after cross-section reduction and heating in the forming area (U) to form a shoulder (S), wherein a point of inflection tangent to the shoulder (S) with the central axis (MW) of the workpiece (W) forms a right or nearly right angle. The invention also relates to the formed workpiece (W) produced by said method and the device required for this purpose.
