As an industry advances technology appears and it is always evolutionary. Those who do not keep in tandem with technological upgrades perish. Specific industries have always been subjected to research and development which leads to better technology holistically.
Some of the recent developments find space in my blog here.
Electronic Beam Melting (& Selective Laser Melting) the former is used in the purification of metals with high melting points often used in making alloys used for fabrication. Both are used in the fabrication of complex alloys.
Usually, free electrons in a vacuum are used to form a fine beam which is used for melting purposes. This is possible whence the beam collides with solid-state matter wherein the electrons are converted to heat for melting. The process finds multiple uses besides welding. This form of welding in industries began as early as the nineteen fifties.
The heat generated at the target helps in the process of heating applications. Due to the vacuum, the transformation is pure or absolutely sterile. Using large vacuum furnaces and strong beams steel can be produced without any impurities.
The technology can also be used to cut an accurate bore. The resulting finish is better than using thermal cutting processes. Computer-controlled systems aimed accurately at selected work site it is useful for annealing, hardening, and tempering.
Using an additive manufacturing process material can be efficiently joined using 3-D model data. Due to the high cost, the technology is used for valued production only. One fine example is electronic beam free-form fabrication used for a net-like finish wherein less raw material and less finish is the net gain.
The equipment used usually comprises the following:
- The Electronic Gun.
- Vacuum Chamber.
- Positioning Mechanism.
- Controlling Equipment.
- Power Supply.
