Base Material Identification
Base material identification is the process of determining workpieces unequivocally based on mill test certificates and markings. This prevents mix-ups in production and ensures correct processing.
Physico-chemical mechanism of action
Base material identification is based on comparing markings, mill test certificates, and the chemical properties of the workpieces. It is verified whether the actual properties match the specified data.
Metallurgical relevance & risks in welding
Mix-ups of material grades can lead to serious errors. For example, a finer or stronger steel than intended could be used, resulting in insufficient strength or excessive stress buildup. This increases the risk of cracks and fractures.
Workshop practice & action instructions
1. Check markings: Check the mill test certificates for correct markings and compare them with the specified data in the order.
2. Chemical analysis if needed: If there is doubt, perform a chemical analysis to confirm the exact composition of the material.
3. Documentation: Record all checks and results in the workshop file for traceability and documentation.
