Heat Staking Due to this effect, the electron beam converges to some minimal diameter in a plane close to the anode. For proper functioning of the electron gun, it is necessary that the beam be perfectly adjusted with respect to the optical axes of the accelerating electrical lens and the magnetic focusing lens. In a similar mode the fine computer-controlled beam can "write" or "draw" a picture on the metal surface by melting a thin surface layer. After leaving the anode, the divergent electron beam does not have a power density sufficient for welding metals and has to be focused. In this way narrow beams of electrons carrying high kinetic energy can be formed, which upon collision with atoms in solids transform their kinetic energy into heat. After passing the focusing lens, the beam can be applied for welding, either directly or after being deflected by a deflection system.

The last mentioned may be very complex if it is to provide computer-controlled imaging, engraving, or similar beam applications. This allows for a very high volumetric power density, which can reach values of the order 10, to achieve high power density in the beam, the emission. Welding speed The construction of the welding equipment should enable adjustment of the relative speed of motion of the workpiece with respect to the beam in wide enough limits, e.g., between 2 and 50mm/s. The focusing effect of a rotationally symmetrical magnetic field on the trajectory of electrons is the result of the complicated influence of a magnetic field on a moving electron. welding They cannot leave the metal unless their kinetic energy (in eV) is higher than the potential barrier at the metal surface. When electrons from the beam impact the surface of a solid, some of them may be reflected (as "backscattered" electrons), while others penetrate the surface, where they collide with the particles of the solid. As a source of electrons for electron-beam welders, the material must fulfill certain requirements: These and other conditions limit the choice of material for the emitter to metals with high melting points, practically to only two: tantalum and tungsten. There is a third electrode charged negatively with respect to the cathode, called the Wehnelt or control electrode.
