Beam Welding
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.
