Electron beam welding (EBW) has many applications and uses. As demands for precision technology grow, so too does the uptake of EBW in a range of sectors.
EBW involves creating the correct conditions for movement of electrons. When channelled, the electrons form a finely-focused energy beam with a strong enough power density to melt metals. These re-bond into a reliable joint.The process is valued because the weld can normally be achieved without filler and in a single pass, and with minimal metallurgical disturbance. This increases strength and reliability, whilst offering significant productivity increases.
Therefore, EBW has many applications for industries that require strong, reliable joints for complex parts. These include:
Flight-critical components which almost always require welding will encompass EBW. The method offers low distortion, which ensures accuracy when working with exotic alloys such as titanium and nickel alloys. The sterile vacuum prevents the risk of oxidation that could weaken the joint, resulting in intricate components that have high resilience to engine vibrations. EBW is also widely used to join new components to existing parts. Examples include:
EBW is used in many elements of automotive engineering. EBW is able to successfully join the complex array of metals – such as low carbon steels, micro alloyed steels, titanium alloys, and medium carbon steels which have a carbon content of 0.3% and lower. Parts and assemblies include:
Defence contracts involve some of the most dynamic design demands. EBW is attractive due to its suitability for use in transmission assemblies. Machine-finishing and hardening is carried out ahead of the welding process, and the use of EBW at the end of the process means that distortion is minimised. For defence and similar industries, highly complex projects can be successfully fabricated. Examples include:
The autogenous capabilities of EBW – which allow welding without needing to introduce a filler material – ensures the biocompatibility of the part. EBW is used for medical instruments, surgical tools, and implantable devices. Examples include:
Hostile environments require corrosion, pressure, and stress resistance. EBW responds to this challenge due to the pin-point beam, which minimises the zones affected by the welding heat. Combined with the single-pass process, this results in high weld integrity. Sample parts include:
Power transmission involves complex assemblies with dissimilar materials. Assemblies have to be able to withstand vibration and heat. Examples include:
This industry requires exceptional quality control and best practice procedures to be endorsed.
