A generic data structure for the specific domain of robotic arc welding

Abstract

The systematic analysis of robotic arc welding processes requires unified structured data, which is currently not available due to the diversity of data sources. This paper proposes an integrated data structure for the specific domain of robotic gas metal arc welding. The presented data structure contains a description of the welding system, the design of the welded parts, welding instructions, and time series of measured process data. Collected data enriched with semantic context is stored and analyzed using this data structure. The usefulness is exemplified but not limited by a use-case suggesting welding process parameters to the worker.
