The move sees the MTC become one of the first research centres in the world to install such a brazing head, with savings in time and tooling changes, plus greater automation the stated pay-off for users.
Still at prototype stage, the equipment has been supplied by Precitec and is capable of laying down a filler wire for brazing and welding operations in any direction or orientation.
The new technology optically tracks the weld seam, allowing for changes in direction, making it possible for the processing head to maintain correct orientation throughout the process. The new application means quicker, more accurate processes, less waste and easier programming.
Previous techniques were time consuming, requiring careful alignment and positioning of the processing head, and restricted in being able to process complex 3D surfaces having limited access. This resulted in variations in weld quality and a limitation to the complexity of processes that could be handled.
While a small number of prototypes are being tested in the automotive industry for brazing car bodies, the MTC is developing the new, more flexible process to improve efficiency and productivity in aerospace, medical and other industrial applications.
MTC senior research engineer Kevin Withers says: “Our research engineers are already leaders in the field of high integrity fabrication. The new equipment increases our laser processing capability, allowing us to apply cutting edge technology to improve manufacturing efficiency across many industrial sectors. This will result in improvements in quality and massive savings in time and cost.”
The new equipment also uses high laser power to ensure rapid and ultra-accurate processing, providing industry-leading precision and speed, creating a competitive advantage for the MTC’s members and customers, the organisation underlines.
- The MTC opened in 2011 and was founded by the University of Birmingham, Loughborough University, the University of Nottingham and TWI Ltd. Industrial members include some of the UK’s major global manufacturers. The MTC aims to provide a competitive environment to bridge the gap between university-based research and the development of innovative manufacturing solutions. It is part the High Value Manufacturing Catapult, supported by Innovate UK.
