What we do
Electron beam welding
Electron beam welding (EBW) is a specialist metal joining technique used to create high integrity joints with minimal distortion.
Benefits of Electron beam welding
- Low heat input for the welded parts;
- Minimal distortion;
- Narrow melt zone (MZ) and narrow heat affected zone (HAZ);
- Deep weld penetration from 0.05 mm to 200 mm (0.002” to 8”) in single pass;
- High welding speed;
- Welding of all metals even with high thermal conductivity;
- Welding of metals with dissimilar melting points;
- Vacuum process yields in clean and reproducible environment;
- Natural welding process for oxygen greedy materials such as titanium, zirconium and niobium;
- Machine process guaranteed for reliability and reproducibility of the operating conditions;
- Cost-effective welding process for large production in automatic mode; and
- Parts can mostly be used in the as welded condition – no sub-machining required.

Electron beam welding process details
Electron Beam Welding is a method which uses a focussed stream of high energy electrons generated by a filament and directed to the joint requiring to be welded. The heating is very localised and the bulk of the assembly therefore remains cold and stable. This results in a very narrow weld with a minimal heat affected zone. There is no need to use filler metal as the parent metal of the assembly is melted. As this is a line of sight method it is not possible to weld around corners or re-entrant angles. Weld depths of up to 30mm can be produced and computer controls ensure minimal operator dependence, thus providing good reproducibility throughout a batch of components, even though this is a piece part process. Since the heat input is very localised it is possible to weld together previously heat treated components, which is a very economical method for producing composite gear shafts, with for example a case hardened gear on a hardened and tempered shaft.
