Wire-based Directed Energy Deposition
Wire-based cladding is a manufacturing process where a metallic wire is continuously fed and melted. It uses a high-energy heat source to process layer by layer.
Physical-Chemical Mechanism of Action
Wire-based cladding uses a continuously fed wire and a high-energy heat source to process layer by layer. The wire is melted and simultaneously fed with a gas jet or other heat source to control the process.
Metallurgical Relevance & Risks in Welding
Controlling the temperature and feed rate is crucial. Inaccurate settings can lead to unevenness in the deposit, porosity, or lack of fusion. Additionally, excessive temperature can alter the material's microstructure and impair its mechanical properties.
Workshop Practice & Instructions
To successfully perform wire-based cladding, the following parameters must be maintained:
• Temperature: The heat source must be set to a constant temperature to ensure even deposition.
• Speed: The wire feed rate must be controlled to ensure layer thickness and deposit quality.
• Gas Jet: The gas jet direction and pressure must be correctly set to optimize the cladding process and avoid porosity.
