Cambridge Vacuum Engineering and Cranfield University Solve Optics Contamination in Laser in Vacuum Welding

by Anna

Cambridge Vacuum Engineering (CVE) and Cranfield University have successfully completed a Knowledge Transfer Partnership (KTP) focused on solving optics contamination in Laser in Vacuum welding. This collaboration has overcome a persistent issue hindering the adoption of this joining technique, which offers deeper penetration welds compared to conventional laser welding methods.

Laser in Vacuum welding, while effective, faced challenges due to optics contamination. Over two years, CVE and Cranfield University, supported by Innovate UK funding, developed a unique optics protection system that operates effectively with low particulate generation. The project received the highest grade of ‘Outstanding’ from Innovate UK.

The collaboration has led to the development of an optical protection system ensuring cleanliness levels comparable to electron beam welding. This breakthrough allows CVE to build Laser in Vacuum welding machines featuring the technology for industrial applications, enhancing productivity, efficiency, and weld quality.

CVE’s comprehensive welding solutions, including Laser in Vacuum, complement electron beam and standard laser welding techniques, offering a technology-agnostic approach for bespoke solutions. The success of this KTP project paves the way for the commercial exploitation of Laser in Vacuum welding in various industries.
