Base Material Certification
Base material certification is a document confirming the chemical composition and mechanical properties of a metal. It is used to ensure that the material used meets the specific requirements.
Physico-Chemical Mechanism of Action
The base material certification contains data on the chemical composition of the metal, such as the content of carbon, silicon, or other elements. This information is crucial for understanding the mechanical properties and behavior of the material under various conditions.
Metallurgical Relevance & Welding Risks
Wrong materials can lead to undesirable properties, such as too low strength or increased susceptibility to cracking. A faulty certification can cause the metal to not meet the necessary technical standards, which poses risks in service and maintenance.
Workshop Practice & Action Instructions
Before a metal is used, it must be certified. This is done through laboratory tests that analyze the chemical and mechanical state of the material. The results are recorded in an inspection certificate. It is important that all materials are certified before use and that these certificates are checked to ensure they are valid and current.
