POLE TUBE

摘要

The invention discloses a pole tube (1) and a solenoid actuator provided therewith, having an intermediate piece (4) to which a pole piece (2) and a tube piece (6) are attached, which together delimit an accommodating area (8) for an armature (10) of the solenoid actuator. According to the invention, the geometry of the end-face regions, which are connected by means of welding, of the intermediate piece and the tube piece and the pole piece is selected such that, taking into consideration the melting points of the materials used, the electrical resistance of the joining partners in the joining region is essentially the same, with the result that, in the case of resistance welding, the heat input to both joining partners is approximately the same.
