Plastics welding process data

The dataset was acquired during the research project FloWeld, which researches the usage of heatflux sensors in the process of plastics-welding. It consists of 68 weldings with the material PP-H (Polypropylen Homopolymer) and 69 weldings of PVC-U (Polyvinylchlorid unplasticized). The dataset contains timeseries data recorded during the welding process itself as well as features extracted from those timeseries based on domain knowledge. The duration and the temperature of the weldings was varied on purpose throughout the experiment, therefore weldings with different flexural strengths were created with five weldings per experimental point.
