Laser Material Processing Undergraduate Research Position Department of Physics, Engineering Physics and Astronomy Dr. James Fraser’s Lab

Posted: February 12, 2021
Application Deadline: February 28, 2021

Electric powertrains are becoming more common as we move to replace combustion engines in vehicles to reduce carbon emissions. With the manufacturing of electric powertrains comes the challenge of assembling thousands of lithium ion cells into a battery pack to store energy for the vehicle. This assembly is typically done using lasers to weld the cells together, however this often involves welding materials like copper or aluminum, which have inherently unstable processes. To make these processes more controllable, we use inline coherent imaging (ICI), an interferometric measurement tool (similar to optical coherence tomography), to measure weld depth during the process.

As a summer student, you would work as a part of the Fraser group with graduate students to:

● Weld samples using our 1 kW laser welding cell

● Design and implement conductivity measurement processes for finished weld seams

● Design and implement strength testing methods for welded joints

● Design algorithms to improve ICI weld depth tracking

● Analyze ICI data

Interested applicants should send a resume, transcript (unofficial is fine) and brief cover email explaining why they are interested in this position to tessa.krause@queensu.ca .
Applications will be reviewed until the position is filled.
