What Is Electron Beam Welding?
In simple terms, electron beam welding (EB Welding) is accomplished by heating a tungsten filament which then releases a stream of electrons through an electromagnetic field, focusing them into a precise beam of energy less than .010″ (0.254 mm) in diameter. As the beam penetrates the surface of the work piece, using no filler and with a heat concentration of up to 500 times that of conventional welding methods, electrons transform metal beneath the beam through a molten state to a gas, allowing the beam to travel deeper and deeper. As the beam penetrates the material, the small gas hole produced closes rapidly, and the surrounding molten metal then fuses, causing minimal distortion and heat effect outside the weld zone.
