Electron beam welding is used for joining metallic materials with normal welding seam depths. The very thin weld seam its narrow heat affected zones drastically minimises the energy transferred and the distortion to the component as whole. Components that have a tendency to distort and subassemblies that require a high level of mechanical pre-processing can be joined using this method without being damaged.
Customers worldwide, from the automotive, aerospace, and turbomachinery industries to branches of mechanical & electrical engineering and research & development profit from our reliable, innovative technologies, know-how and years of experience as electron beam specialists.
