Predictive Quality Arc Welding Dataset The dataset comprises various current and voltage time series. Both currents and voltages are synchronously sampled at a frequency 100 kHz, with a maximum permissible error of 0.5%. Raw data Column Name Description ------------ ---------------------------------------------- experiment ID of the experiment run welding_run ID welding in one experiment cycle ID cycle in one welding run I Current V Voltage quality Quality label (0: bad weld quality | 1: good weld quality | -1: no label) Preprocessed data Column Name Description ------------ ------------------------------------------------------------- experiment ID of the experiment run welding_run ID welding in one experiment label Quality label (0: bad weld quality | 1: good weld quality | -1: no label) V_0 Voltage at the beginning of the cycle (t_0) ...
