Full Project Detail

Laser Processing is currently a massive growth area for a wide variety of sectors including Automotive & Aerospace engineering and general manufacturing. Consequently, there is significant interest in the research in the area of laser materials processing such as laser milling and laser welding. For the latter, gas shielding is a crucial ingredient since oxidation in the welding zone increases the grain size within the weld - which alters the weld’s resistance properties - and prevents from a reasonable reproducibility of the weld quality. This project focuses on the design and additive manufacturing of an optimized gas shielding nozzle for laser welding processes able to provide a laminar flow of Argon with minimum flowrate and thus avoid oxidation of the welding zone at minimal cost.

Entry requirements

Applicants should have, or expect to achieve, at least a 2:1 Honours degree (or equivalent) in Mechanical Engineering or a related subject. A relevant Master’s degree and/or experience in one or more of the following will be an advantage: Mechanical Engineering, Fluid Mechanics.
