Wire Arc Additive Manufacturing
Wire arc additive manufacturing is a manufacturing method where a metallic wire is built up layer by layer to form components. It uses arc radiation and offers high deposition rates for large build volumes.
Physical-Chemical Mechanism of Action
Wire arc additive manufacturing uses the high temperatures of an arc to melt a wire in contact with a workpiece surface. The wire is continuously fed and thus forms layers on the component.
Metallurgical Relevance & Risks in Welding
Temperature control is crucial to ensure a homogeneous bond. Excessive temperatures can lead to overheating and distortion, while too low temperatures can result in insufficient bond strength.
Workshop Practice & Instructions
Use a stable arc and control the wire speed and temperature. An optimal build-up height of 2-3 mm per layer is common. Ensure the wire is clean and free of contaminants.
