Rejection Limit
The rejection limit is a set value for mechanical or hardness properties, beyond which a component is considered defective. It is based on technical requirements and delivery conditions.
Physical-Chemical Mechanism
The rejection limit is a specific threshold that defines when a component no longer meets its mechanical or hardness properties. These limits determine the material's behavior under certain loads and temperatures.
Metallurgical Relevance & Welding Risks
If the rejection limit is exceeded, the component can suffer from cracks, failure, or insufficient toughness. This can lead to safety issues and increased repair costs.
Workshop Practice & Instructions
When welding, it is important to ensure that the mechanical and hardness properties of the component remain within the specified rejection limits after the process. This requires careful selection of welding parameters such as temperature, voltage, and time. If necessary, additional tests should be performed to ensure the rejection limit is not exceeded.
