Cambridge Vacuum Engineering shortlisted for prestigious energy award

Press Release

Cambridge Vacuum Engineering (CVE) – a specialist in power beam welding technologies – has been shortlisted for a prestigious International Energy Award for its ground-breaking RapidWeld project. RapidWeld saw CVE work alongside industry partners to fast track the production of an offshore wind turbine monopile foundation destined for the Dogger Bank Wind Farm. During the project, CVE and the RapidWeld team demonstrated that critical pieces of energy infrastructure can be produced up to 25 times quicker if the correct electron beam welding technologies are deployed.

Organised by the Energy Institute, the annual International Energy Awards celebrate game-changing and disruptive technologies that are supporting the transition to net zero and / or extending universal access to energy. CVE has been shortlisted in the ‘International Energy Technology Award’ category, alongside five other businesses including Octopus Energy and UK Power Networks.

The RapidWeld project was funded by Innovate UK and led by a consortium including CVE, SSE Renewables, DNV, Sif Netherlands B.V., Agile NDT and The Welding Institute (TWI).

Harnessing CVE’s innovative Ebflow technology, the consortium delivered the first-ever electron beam welded section to be incorporated into an offshore wind turbine monopile foundation (transition piece). Ebflow uses a local vacuum system that creates and maintains a vacuum around only the seam that is being welded. Significantly quicker, cheaper and cleaner than conventional welding techniques, this innovative method can be used on the largest structures. During RapidWeld, CVE demonstrated that it is possible to weld monopiles far quicker than current methods. It also proved that Ebflow uses 90% less energy, costs 88% less, and produces 97% less CO2 emissions.

Bob Nicolson, Managing Director at Cambridge Vacuum Engineering, said: “Once complete, Dogger Bank will become the world’s largest offshore wind farm. The scale of the project and its ambitious delivery timeline necessitates the use of novel technologies that can expedite construction, whilst maintaining the highest quality standards. As a team, we were excited to get RapidWeld off the ground and honoured to deploy our Ebflow solution on such an important energy infrastructure initiative. The results we achieved were outstanding and to be shortlisted for an award for the project is the icing on the cake.

“Our nomination is testament to the partnerships we forged across the RapidWeld consortium. It also reflects CVE’s ongoing commitment to innovation and excellence within the energy sector and to finding innovative solutions to complex engineering challenges that can support the journey to net zero. RapidWeld was an incredible project to work on and we are excited about what could be achieved by scaling up the use of electron beam welding in this and other similar renewable energy projects. We eagerly await the outcome of the awards ceremony.”

Cambridge Vacuum Engineering and Cranfield University project paves way for wider industrialization of Laser in Vacuum welding

Press Release

Groundbreaking Knowledge Transfer Partnership solves optical contamination issue

 

Cambridge Vacuum Engineering (CVE) – the power beam welding specialists – today announced the successful completion of a Knowledge Transfer Partnership (KTP)* with Cranfield University that will increase welding options available to engineers worldwide. Together, the two organisations have solved the undesirable optics contamination phenomenon associated with Laser in Vacuum welding, paving the way for full scale industrial exploitation of the technology.

The conclusion of the KTP is set to yield tangible benefits for companies that want to achieve deeper penetration welds, while also improving weld quality, reducing oxidation, and minimising the time needed for part cleaning, post welding.

Laser in Vacuum welding is a relatively new joining technique that can be used to tackle some of the most demanding welding tasks. The technique can achieve two to three times the depth of weld compared to conventional laser welding methods. However, to date, the issue of optics contamination** has hindered its widespread adoption across industry.

With a shared vision to drive forward innovation, CVE and Cranfield University joined forces to research innovative solutions to this persistent issue and enable the seamless integration of Laser in Vacuum welding into various industrial applications. Over the last two years, using Innovate UK funding, the teams set up test systems at both CVE and Cranfield to study different aspects of the Laser in Vacuum process and trial various concepts and solutions. Experiments on these systems provided the team with a robust data set on various phenomena associated with optical contamination, as well as the secondary effects of the potential identified solutions. This data was then used to develop a unique optics protection system – using a first principles, physics-based approach – that operates effectively with very low levels of particulate generation. Several trials were conducted with customers, providing further assurances about the capabilities of Laser in Vacuum welding, and validating weld quality in a range of applications, materials and joint configurations.

The project has subsequently been awarded the highest grade of ‘Outstanding’ by Innovate UK and Cambridge Vacuum Engineering is now building Laser in Vacuum welding machines featuring the technology for its customers in industry.

Commenting, KTP Project Lead and Head Laser Development Engineer at CVE, Max Nentwich, said: “This project is a significant milestone in the commercialisation of Laser in Vacuum welding. By addressing the optics contamination issue, we can now unlock the full potential of this form of welding – enabling it to reach full industrial maturity. As a team, we are incredibly proud of this breakthrough and grateful to Innovate UK and Cranfield for their support. On a personal level, as a recent graduate, I’m delighted to have led such a meaningful project. It was a privilege to conduct research that will have immediate implications for industry and help deliver enhanced levels of productivity, efficiency, and quality for end users.”

CVE’s optical protection system ensures cleanliness levels of welded parts comparable with electron beam welding, while guaranteeing a long laser coupling-in window life. The low-cost consumable windows last for up to three hours of welding at a low power (3kW) with no appreciable weld degradation.

Steve Horrex, Sales Director at CVE, said: “Congratulations to Max and the team at Cranfield for completing this project with such exceptional results. It’s rare for a recent graduate to be put in charge of such a large KTP, but we knew from the start that Max was the right project lead. To be awarded such an impressive grade by Innovate UK validates the future impact of this project and we look forward to taking the results to market to deliver commercial benefits across the sectors we work in.”

Dr. Wojciech Suder, Senior Lecturer at Cranfield University, said: “Laser welding in vacuum can overcome many limitations of atmospheric laser welding, opening a myriad of new applications. Working with Max and the CVE team enabled us to put the required expertise together quickly and develop this technology very efficiently, making real impact. Well done to the team for converting a lab idea into a commercial system is in just over two years. I look forward to seeing this technology revolutionizing thick section and specialized welding applications.

Jody Chatterjee, Knowledge Transfer Advisor at Innovate UK (KTN), said: “This was a highly innovative and productive KTP project between CVE and Cranfield University, where the knowledge transfer was project managed and the outcomes delivered by Max, an excellent Associate.  There are over 800 KTP projects throughout the UK each year with companies, charities, non-profits, and the public sector, across a range of industries and sectors covering STEM, management, and other topics.’’

Laser in Vacuum welding complements electron beam and standard laser welding techniques, with each approach possessing different strengths and weaknesses. Offering all three types of welding, Cambridge Vacuum Engineering can take a technology agnostic approach, providing customers with bespoke solutions optimised to meet different application needs and engineering challenges. Laser in Vacuum welding is most suited to projects where higher penetration welds are required or gas-sensitive materials are used. In these scenarios, standard laser welding can struggle to achieve the right results. Many of the process variables influencing weld quality associated with standard laser welding, such as shielding gas composition, nozzle design, and melt pool instabilities, are eliminated using a vacuum.

(**) During laser welding, the creation of vapour and particulate (soot) can prove problematic. With other forms of welding, operators manage the build-up of vapour and particulate by using gas protection systems. However, with laser in vacuum welding, the use of such system can negate some of the advantages of the vacuum – turning process emissions from welding into a fine particulate that coats the inside of the welding chamber and the workpiece. In laser in vacuum welding, proper soot extraction is a challenge due to the lack of atmosphere. The deposited powder is harmless in small quantities but begins to present a more significant risk when it builds into a thick layer. This can happen quickly when the machine is in heavy use. Airborne metal oxide powders can be toxic and present an explosion and fire risk. These risks are mitigated, but not avoided entirely, with regular cleaning. This conflict with health and safety requirements, as well as cleanliness standards, is unacceptable for many industries.
