Research summary
Wire arc additive manufacturing (WAAM) is attracting interest from the manufacturing industry because of its potential to produce large metal components with low costs and short lead times for production. Dr. Ali Nasiri, Canada Research Chair in Ocean Engineering, aims to realize the full potential of this state-of-the-art technology to make large-scale components with tailored properties out of stainless steel and corrosion-resistant alloys for marine and offshore applications.
Nasiri and his research team are developing a versatile robotic WAAM platform that can manufacture large-scale engineering components with controlled microstructure and mechanical properties. They are also trying to better understand the corrosion performance of these fabricated parts in harsh marine environments and to advance WAAM technology for hybrid manufacturing and additive repairs.
