Abstract

An axial piston intended for an axial piston machine and comprised of at least two components forming a driving part and a compressing part. To enable manufacture of the axial piston in an easy and inexpensive way while simultaneously reducing the weight, the components are manufactured by a solid forming process and joined together by a capacitor discharge welding process.

Claims (9)

1. A method for producing an axial piston comprising at least two components, forming a driving part and a compressing part, said method comprising:

producing the two components by a solid forming method which is a cold extrusion process,

machining welding areas of at least one of the components,

positioning a free end of the compressing part in relation to an outer periphery of the driving part,

joining the components by a capacitor discharge welding process at the machined welding areas,

heat treating the axial piston.

2. The method according to claim 1 , wherein the compressing part is butt welded on the driving part.

3. The method according to claim 1 , wherein the two components are nitrated.

4. The method according to claim 1 , wherein the two components are heat treated after the welding process.
