Electron Beam vs. Conventional-No Contest

Electron beam welding represents the benchmark in metal joining technology. It concentrates an extremely dense point of energy in a small area. This extreme density, along with the ability to control width, depth and heat, results in the highest quality welds. Part distortion and weld stresses are kept to an absolute minimum. And weld contamination is eliminated, because the process takes place in a vacuum.
 
Since the electron beam’s intensity is enough to vaporize any known materials, it even allows the joining of dissimilar metals…one of many engineering feats that have remained impractical, if not impossible, with conventional welding techniques.
 
But the applications of electron beam welding aren't just limited to the exotic. We provide the same precision welding, and at cost-efficient production rates, to dozens of more down–to-earth industries.
 

Electron Beam Welding = Practically-Applied Technology

 
Electron beam welding was introduced commercially in 1959. It employs a special electron beam gun that emits a highly-energized stream of electrons. This stream can be accurately focused onto the welding surface with full control over weld width, penetration and heat generation.
 

Performing the Impossible

 
Electron beam welding can perform welds as narrow as a few thousandths of an inch or wider than a quarter of an inch. Weld penetrations can be controlled from .0025”; to up to 2” in steel.
 

The Clean Beam

 
Because electron beam welding is performed in a vacuum, welds are clean, free of oxidation. Filler material is not usually utilized, and weld ratios can be as high as 20-to-1 (depth-to-width) compared to the 2-to-1 ratio of tungsten inert gas welding. There is little (if any) distortion, and shrinkage is minimal.
 
The electron gun can be located as far as 25” from the work surface and is accurately guided by a precision, operator-controlled mechanism. This allows the beam to be directed into restricted, normally inaccessible cavities where conventional welding processes are severely limited.
 
The heat energy levels are high enough to vaporize most materials, yet heat dissipation is fully controllable around the work surface. Electron beam welding permits effective joining of dissimilar exotic metals with minimal effect on surrounding components.
