Laser and electron beams are used as tools for welding, cutting, drilling, melting, tempering or vaporizing in many machining tasks. These beams have fundamentally different physical natures. They are produced differently, and behave differently when penetrating material. The differences between electron and laser devices that occur in machining, the advantages and disadvantages of these technologies in comparison with on another, will be discussed in this article.
