Title: Advancing Laser Manufacturing with Optical Process Monitoring
Speaker: Dr. Tristan Fleming, IPG Photonics Canada
Date and time: Sunday, August 25, 2024, 1-2pm
Location: MP102, McLennan Physical Laboratories, 255 Huron St, Toronto, ON M5S 1A7
Abstract: The laser has become a tool of choice for advanced manufacturing, highlighted by its critical role in the electric vehicle (EV) market. However, the sophistication of laser welding processes has introduced new challenges for manufacturers. Mistakes in manufacturing can be costly, dangerous, and reduce emission savings through increased scrap. IPG’s LDD product offers a solution.
At the heart of the IPG’s LDD product is inline coherent imaging, an interferometric technique similar to optical coherence tomography (OCT). Using this technique, LDD provides real-time, in situ measurements of laser weld depth at micron-resolution and high-speed (>200 kHz), as well as 3D images of parts before, during and after the welding process. These measurements provide actionable quality assurance data for manufacturers, allowing them to detect and correct process defects and improve production yield.
With a proven impact on high-volume production, LDD is a growing part of IPG’s business, as evidenced by the construction of a new facility in Kingston. We are excited to speak with prospective students about opportunities within IPG.
Bio: Tristan Fleming completed his doctorate at Queen’s University at Kingston, Canada in 2022, including two years at University College London. During his degree, he applied the weld depth measurement technology underpinning the IPG’s LDD product to laser additive manufacturing. A world-first, he also exploited high-speed synchrotron X-ray imaging to validate and further develop the LDD product. After graduation, he joined IPG Photonics Canada as an Applications and Research Specialist.
