    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...

    This paper reports a statistical analysis of the multiple-pass laser cutting of dry and wet pine wood with a single mode Ytterbium fibre laser. The laser wood-cutting is a multi-factor process requiring parameter optimization to deliver good quality cuts at optimum process efficiency. This study employs a Des...

    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...
