Electron Beam Melting
Electron beam melting is an additive layer-by-layer process that uses a high-energy electron beam to melt metallic materials. Operating in a vacuum reduces residual stresses.
Physical-Chemical Mechanism
An electron beam melter generates a high-energy beam that melts metal materials. The process is conducted in a vacuum to prevent reactions with air and other gases, which improves control over the melting process.
Metallurgical Relevance & Risks in Welding
The high energy of the electron beam enables precise melting with minimal distortion of the workpiece. However, uncontrolled use can lead to overheating, which can alter the microstructure and impair mechanical properties.
Workshop Practice & Instructions
Use electron beam melting for precise melting processes in controlled environments. Ensure the vacuum is stable and the beam energy is correctly set. Monitor temperature continuously to avoid overheating.
