Method for tracing forged parts over the entire production process, in particular from the forging process, via sandblasting and heat treatment, to mechanical processing

A method for tracing forged parts over an entire production process, comprising:

• capturing process parameters of a forging process;
• marking a workpiece produced in the forging process with a first identifier by a mechanical or thermal penetrant method;
• storing the captured process parameters of the forging process together with the first identifier of the workpiece in a database;
• reading the first identifier from the workpiece;
• capturing subsequent process parameters during a subsequent process step of the production process;
• storing the subsequent process parameters of the subsequent process step in the database for the read first identifier in response to the first identifier of the workpiece remaining legible during the subsequent process step of the production process;
• marking the workpiece with a further identifier by a surface inscription method in response to the first identifier of the workpiece not remaining legible during the subsequent process step of the production process;
• and
• storing the subsequent process parameters of the subsequent process step together with the further identifier together with the captured process parameters and the first identifier in the database.
