Wide range of material choice including metal combinations not weldable conventionally.
Very low distortion and exceptional weld quality allows parts to be finished machined prior to welding
Welding of dissimilar materials provides choice of using high cost, high performance metals only where essential for performance.
Welding finish machined parts enables the designer to take a modular approach to products, increasing versatility without increasing lead time or inventory.
Post weld machining is largely eliminated, which enables more compact assemblies to be designed.
Component parts for EBW require only standard good quality tolerances and tooling is minimal because of very low heat input and distortion.
EBP has 40 years experience as Europe's leading EBW specialist; use it to help improve your product or solve your problem.
Materials
Suitability of materials for EB Welding
