Filler metal production lot
A defined quantity of a welding consumable with constant composition and technical properties. Used for consistent results in production.
Physical-Chemical Mechanism of Action
A filler material batch consists of a defined quantity of a welding filler with a specific chemical composition and technological properties. This batch is produced under controlled conditions to ensure it always has the same properties.
Metallurgical Relevance & Welding Risks
Using a fixed filler material batch is crucial for consistent welding results. If the batch isn't kept constant, chemical or mechanical properties can change, which can lead to unwanted cracks, wear problems, or distortion.
Workshop Practice & Instructions
In the workshop, the filler material batch must be used exactly according to the manufacturer's instructions. This includes the correct amount, temperature, and time for adding the filler. It's important that all batches are identical to ensure consistent weld quality.
