:: Electron Beam Welding Applications::

MODISON offers an Electron Beam Welding (EBW) Service, backed up by experienced staff and comprehensive metallurgical facilities. Feasibility and application studies are undertaken to enable potential users to evaluate the suitability of the technique for their products. Small batch production welding is also carried out.

The Process :

The joint to be welded is heated by bombarding it with a dense stream of high velocity Electrons; the Kinetic energy of the Electrons is converted into heat on impact with the work piece, when focussed to a small spot on the component to be welded.

The energy can be many times greater than that of conventional welding process.

For example, 15 KW can be concentrated on to a 0.25 mm diameter. Weld depth to weld ratio as high as 20:01 can be achieved, compared with 2:1 typical of a tungsten inert gas welds.

Advantages :
  • Simple Joint preparation : Square butt joint is suitable. Thick and thin sections can be welded in a single pass.
  • Minimum distortion : High power density with very low overall heat input, thereby minimum distortion. Can weld high conductivity materials.
  • Minimum post weld machining and heat treatment.
  • Consistent and exceptionally good weld quality: All weld parameters are carefully controlled and the process is automated.
  • Narrow fusion zone.
  • Deep penetration and easy accessibility : Beam can pass through a small gap of around 2 mm to weld in areas otherwise inaccessible.
  • Inert atmosphere (Vacuum)
  • Excellent joint strength (Near parent material strength)
Can Weld…
  • Niobium, Tantalum, Titanium, Monel, Zirconium, Copper, Molybdenum etc.
  • Dissimilar metals : Copper to Stainless Steel, Aluminium to Copper, Tool Steel to Carbon Steel etc.
Machinery Data
  • Beam Power 15 KW
  • Acceleration Voltage 60 KV
  • Vacuum Chamber Size 600 x 600 x 600 mm

Applications :

Electron Beam Welding is used where high integrity and reliable joints are required. It is the most reliable joining process for welding certain materials with very high quality requirements. EB Welding has a high power density, with very low over all heat input, thereby giving minimum distortion. EB Welding has deep penetration, narrow fusion zone and inert atmosphere (Vacuum).

Typical area of applications are :
  • Aerospace
  • Electronics
  • Automotive
  • Parts for Turbines and Jet Engines
  • Medical Equipment
  • Power Generation
  • Vacuum Systems
  • Oil and Petro-Chemicals
  • General Mechanics
  • Steam Turbine Parts
  • Surgical Tools
  • Hermetically Sealed Part
