CAMBRIDGE VACUUM ENGINEERING

CVE has developed a local vacuum EB welding system which can be readily transported and operated on site and applied to structures significantly larger than can be accommodated in a vacuum chamber. Ebflow eliminates the need for a vacuum chamber through a local, coarse vacuum which is established and maintained only where it is needed. High performance EBW can take place in any plant where large components are welded on a large scale as long as adequate shielding from X-Rays can be provided. Using a system of sliding seals and precision handling enables fast longitudinal and circumferential welds on large work pieces. A coarse vacuum is ideal for thick section welding - achieving the fastest thick section welding rates ever. There is no filler wire, the autogenous weld can be heat treated and the weld rendered metallurgically indistinguishable from the parent material.
