Claim 0:
1. A method for producing a probe of a thermal flowmeter for measuring mass flow of a medium in a measuring tube, the method comprising:
providing a probe core disposed loosely in a probe sleeve having a longitudinal axis; and
deforming the probe sleeve completely radially relative to the longitudinal axis in the direction of the probe core using high energy rate forming such that a material-locking connection is formed between the probe sleeve and the probe core and a rod is produced,
wherein the rod defines a base body, or a separated section of the rod defines the base body, from which base body a probe is manufactured,
wherein a radial deformation speed of the high energy rate forming reaches values greater than 100 m/s, and wherein the high energy rate forming is performed using explosive forming,
and wherein the explosive forming comprises the steps of placing an explosive substance on an outside surface of the probe sleeve and igniting the explosive substance.
