Abstract

This paper presents a knowledge model of the laser beam welding (LBW) in the aircraft industry, which is developed through the utilisation of integration definition for function modelling and concept mapping. The developed knowledge model has been captured in the form of rules and recommendations, which is commonly used as guidelines in this field, and represented with unified modelling language. The LBW component development comprises four key stages, namely, structure design, process planning, fixture fabrication and component fabrication. This has been achieved through the adoption of a three-phase qualitative research methodology: data collection and analysis, knowledge model development and validation. The captured knowledge in the form of rules and recommendations has developed an understanding of the LBW in the aircraft industry and improved the structure design and process planning from joint type selection, structure dimension definition and process parameter optimisation, etc. A prototype handbook has been developed based on skin-stringer connection of aircraft fuselage to guide designers and engineers directly in developing laser beam-welded fuselage panels. The procedure of knowledge modelling for the LBW as well as the methods and tools adopted can be applied to other processes. The developed knowledge model has been validated through a case study.
