Cambridge Vacuum Engineering launches new technology for large structure welding

Cambridge Vacuum Engineering (CVE) has launched EBFLOW, a new technology that can improve the efficiency of large-scale manufacturing projects by enabling firms to perform electron beam welding without a vacuum chamber. The technology is designed to simplify the process of thick section welding in the manufacturing of a wide range of large structures including ships, pressure vessels, wind farms and towers, nuclear plants, and many of the structures involved in oil and gas exploration and civil engineering projects.

EBFLOW features a coarse vacuum which can be mounted on tracks and operated locally. This technology can be put to use in any plant where large components need to be welded. Through various tests, EBFLOW has proven to be 20-30 times faster than conventional arc welding, thereby resulting in transformational gains in productivity. At the same time, it uses less power than conventional arc processes, hence lowering a plant’s carbon footprint. Other benefits of the technology include the ability to perform low-heat input welds which result in reduced distortion and the option to perform non-destructive testing immediately after welding. These help in fast-tracking the manufacturing process and thus driving down costs.

CVE designs and builds process solutions and has more than 60 years of experience in manufacturing electron beam systems and vacuum furnaces. The equipment offered by CVE includes systems ranging from 50 kV to 200 kV with beam powers of up to 100 kW.
