We all know laser welding, we could almost all – with the appropriate equipment. Electron beam welding knows only a few, even among welding experts. That might have changed at Schweissen & Schneiden.
- Visitors to the CVE (Cambridge Vacuum Engineering) booth were able to see components welded by EBM, Laser in Vacuum, Ebflow and Evflow, including segments of pressure vessels, an electric motor hairpin stator, turbocharger shaft gear assemblies and copper-manganese resistors.
- Electron beam welding (EBW) produces deep, good quality welds with minimal heat input and distortion and is widely used in automotive, aerospace, aircraft and other industries.
- Ebflow, a vacuum electron beam welding system can be used to join much larger components than is possible in the vacuum chamber. Ebflow is up to thirty times faster than conventional welding technologies and can weld 250 mm thick steel in a single pass. This enables the highest speeds for thick profiles ever. The technique is suitable for welding large steel structures and is particularly popular in the manufacture of pressure vessels for the oil and gas industry, the nuclear industry and renewable energy applications such as monopiles for wind turbines.
- Evflow is an electron beam welding system for electric vehicle (EV) manufacturing. As demand for electric vehicles increases, battery manufacturers are under pressure to produce battery packs faster and more efficiently to support the transition to a low-carbon economy. Evflow can support this type of drive by producing strong, high-quality welds for accumulators, stators, resistors and drivetrain components.
- Vacuum laser welding enables the production of high-quality welds with three times the depth and significantly less weld spatter compared to conventional laser welding.
Steve Horrex, director of sales at CVE, explains, “Over the past few years, we’ve seen manufacturers come under increasing inflationary pressure. Rising raw material and energy prices have nibbled away at their profits, and there have been significant supply chain and labor bottlenecks.
For manufacturers looking to control costs, electron beam and laser welding technologies offer a great way to operate more efficiently and increase production. Since the last Schweissen & Schneiden, demand for our Ebflow and Evflow technologies has increased – especially in the energy and automotive sectors.
After a hiatus of several years due to Covid, we are pleased to announce that Welding & Cutting is back, and we look forward to introducing event attendees to the latest CVE news. “CVE has more than sixty years of experience in the design and production of electron beam and laser welding systems that save customers time and money while improving weld quality. Depending on the application, the machines can be built turnkey to individual customer requirements. CVE offers systems with electron beam powers of 100 kilowatts.
