Ageing bridge network is increasingly affected by corrosion, environmental exposure and growing transport demand. Conventional repair methods can be costly, disruptive and material-intensive, particularly when damage is localised. Laser cladding uses a high-energy laser to deposit metallic material onto damaged steel, forming a bonded repair layer that can restore local section loss without full component replacement. This PhD project will investigate laser cladding as an advanced repair technique for ageing bridges. The project will combine structural engineering, materials characterisation and durability assessment. The successful candidate will undertake experimental testing of damaged and repaired steel specimens, examine bonding and microstructural behaviour, assess fatigue and durability performance, and develop practical repair implementation procedures. The research will be supported by engagement with industry advisors. This project would suit a motivated student with interests in steel structures, bridge engineering, structural testing, materials science, advanced manufacturing, and/or sustainable infrastructure repair. The outcomes will contribute to safer, more durable and more resilient infrastructures.
