Presented at ICALEO 2009
On-line monitoring of the quality of laser welding is of interest for many industrial applications. For photodiodes the monitoring strategy usually aims at observing whether the signal exceeds a threshold. This well known technique is mainly based on empirical values, thus the monitoring has to be trained for each application. For improved understanding of the context between the physics of a welding defect generated and the resulting voltage signal, the experiments were observed by high speed im...$28.00

Presented at ICALEO 2009
Welding had traditionally faced two major challenges obtaining a flawless bond (high internal weld quality) and obtaining a smooth surface transition (high external weld quality). While the former has been, and is being, well researched, the latter has received much less attention, despite the fact that post-weld surface finishing treatments such as machining and grinding can be costly or sometimes i...$28.00

We report studies of laser methods for fabricating large-area, high-quality graphene. Common methods for graphene growth (PLD, MBE, thermal decomposition of SiC) apply energy evenly across an entire substrate, leading to simultaneous nucleation of graphene crystals in many locations and thus poor con...$28.00
