CVE Attend the 23rd Technical Sessions on Welding and Joining Technologies

This week, CVE are at the 23rd Technical Sessions on Welding and Joining Technologies, in Irun, San Sebastian, Spain. Running between the 7th and 9th March 2023, the conference serves as a meeting point for the exchange of knowledge among experts in the welding sector, as well as to update and contrast the opinions of the speakers and attendees. It also represents an opportunity for the dissemination of technical knowledge, offering a means for the development of new technologies in the field of joining technologies.

The session is organised by CESOL, the Spanish Association of Welding and Joining Technologies, an independent and non-profit association of people and companies at the service of welding and other joining technologies. CESOL was created in 1993, and is the result of the merger of ADESOL, the Spanish Association for the Development of Welding, created in 1977, and CES, the Spanish Centre for Welding and Joining Technologies, created in 1988.

CVE’s Development Engineering Manager, Alex O’Farrell, presented on the 7th March at the 1st Technical Session on Welding. His presentation was titled “Electron Beam Welding of Copper Electrical Conductors for Electric Vehicles.”

 

About the Conference

The main objective of the session is to disseminate the know-how of the latest achievements in the field of joining, coating, additive manufacturing and related processes like structural integrity, inspection, quality and environmental management.

The conference will offer welding professionals, their employers, scientists, fabricators and welding-products suppliers the best framework to exchange ideas and information, share knowledge resources, an establish a dialogue intended to open new research directions and to join together in partnerships for new projects development. This 23rd Sessions can be an opportunity to advance in the welding profession, its products and its practices and to continue driving the welding industry forward.

The topics covered include:

  • New technologies in welding and cladding processes and their applications

CVE Win Faraday Challenge Funding

Unkategorisiert
CVE Win Faraday Challenge Funding

Cambridge Vacuum Engineering (CVE) has received funding from Innovate UK under the Faraday Battery Challenge.

A partnership between Innovate UK, UK Battery Industrialisation Centre, and The Faraday Institution, has be constructed to create a challenge that supports the research and development of the most promising, innovative, and sustainable battery technologies for the propulsion of electric vehicles in the automotive sector.

The result is £27.6 million in funding being invested across 17 research and innovation projects and facilities that will drive the growth of a strong battery business in the UK.

Electron Beam Welding

CVE’s proposal, EB-Bat, in collaboration with Delta Cosworth and TWI, will use the funding to design, build and test an electron beam (EB) welding machine that can weld battery busbar components.

Electron beam welding is potentially 20 times faster than laser welding. You can deflect and refocus electron beams much faster than laser beams, as this is achieved using magnetic fields, without moving parts as the welds are made. Plus, EBs do not suffer from reflectivity from copper and aluminium, making more consistent and reliable welds.

The EB-Bat project will provide a compelling demonstration of the process performance, productivity, quality, and economics to the automotive manufacturing sector with an aim to secure funding to take it into production.

Other benefits of welding battery busbars using electron beam over current laser welding methods include:

  • Energy savings
  • Smaller factory footprint
  • A reduction in scrap
  • Welding fume control

Project Partners

The project partners combine a wealth of experience in the automotive industry, with Delta Cosworth, electric vehicle specialists developing innovative battery solutions and part of the wider Cosworth Group; and TWI as a world-leading welding and materials development organisation. CVE, the lead partner in the project, are designers and manufacturers of electron beam and laser welding machines for many applications, including turbochargers.

 

Simon Dowson, Managing Director at Delta Cosworth, commented:

“Developing and manufacturing batteries is one of our core capabilities at Delta Cosworth. We have already made leaps and bounds in delivering flexible battery solutions, our Cylindrical Scalable Modules being at the centre of our battery offering. Creating, more efficient and reliable ways to manufacture our batteries like electron welding will aid us in maximising our battery technology’s potential and give us the possibility to transfer new manufacturing techniques across the wider Cosworth group.” 

 

Tony Harper, Challenge Director for the Faraday Battery Challenge, said:

“As we move towards a net zero future the UK’s electric vehicle industry must continue to evolve. These winning projects have all shown how their ideas can potentially accelerate the development of technologies or business practices in the UK. I look forward to seeing how their innovations help to significantly advance the performance characteristics of batteries for electric vehicles.​”

CVE Enter Cambridge Dragon Boat Festival

CVE has entered the 2022 Cambridge Dragon Boat Festival. The event will take place on Saturday 10th September and is held annually in aid of Addenbrooke’s Charitable Trust (ACT).

Dragon boat racing is the fastest growing water activity, with up to 10 people paddling a 30’ boat, with an additional drummer at the front. The race will take place on a 200m stretch down the River Cam at Fen Ditton. This year more than 40 teams are expected to compete.

View the complete crew list (accurate as of 23rd June 2022).

The Festival promises an exciting day out for all the family and there will be a wide range of bankside activities and food stalls for everyone to enjoy. The Festival is free to spectators.

There are awards for the top three crews, the best-placed mixed crew (minimum 5 ladies), the crew raising the most money for ACT, and the ‘best dressed’ crew.

Addenbrooke's Charitable Trust

As part of the entry, CVE is raising money for ACT. ACT’s mission is to ensure that every patient at Addenbrooke’s and the Rosie hospitals experiences the highest quality of care available. They raise funds for cutting-edge technology, additional specialist staff and extra comforts for patients, over and above what is possible with NHS funding alone.

“Addenbrooke’s Charitable Trust (ACT) is excited to be the official charity sponsor for the Cambridge Dragon Boat Race once again this year. We would love people to sign up for what promises to be a great day full of fun, friendly competition and team rivalry. We’re so grateful that the festival will be raising funds to support ACT this year, helping to make Addenbrooke’s and the Rosie hospitals even better for patients, their families and staff.” – Emma Bray, Corporate Fundraiser
