METHOD FOR THE PRODUCTION OF A PISTON FOR AN INTERNAL COMBUSTION ENGINE AND PISTON FOR AN INTERNAL COMBUSTION ENGINE
First Claim
1. A method for the production of a piston for an internal combustion engine, composed of at least two components, each said components having at least one corresponding joining surface, comprising the following method steps:
- a) pre-working the at least two components, at least in a region of the joining surfaces;
b) covering at least a part of a surface of at least one of the components with at least one covering medium;
c) assembling the at least two components;
d) connecting the at least two components along their corresponding joining surfaces, by means of beam welding, to produce a piston blank;
e) removing the at least one covering medium and any excess weld material adhering to the covering medium; and
f) machining the piston blank to produce a finished piston.
