Electron Beam Melting
Electron beam melting in vacuum is a high-vacuum process that melts metal powder with a high-energy electron beam. This allows precise control of melting processes and the production of fine metal layers.
Physicochemical mechanism of action
A high-energy electron beam is fired at metal powder, leading to rapid melting. The high energy of the beam ensures a quick temperature increase, and melting processes can be carried out at very high temperatures.
Metallurgical relevance & risks in welding
This method allows precise control of melting processes, leading to better homogeneity and accuracy of metal layers. However, a lack of vacuum or insufficient beam energy can lead to incomplete melting or contamination, compromising the quality of the final metal structure.
Workshop practice & action instructions
To successfully perform electron beam melting in vacuum, a highly efficient high-vacuum device must be used. The beam energy must be precisely set, and the vacuum pressure should always be checked. Inadequate evacuation can lead to contamination, affecting the quality of the metal layers.
