RSW gun fault prediction benchmark data set (demo)

The resistance spot welding (RSW) welding gun fault prediction benchmark data set has 72 multivariate time series in the training set and 8 in the testing set. Each time series length 604800 sampled at 1 Hz with missing values and has 20 dimensions (c1-c19 and the error code). We retain the missing value and the outliers of the welding gun time series for the potential of imputation research in the future.<br> This data set supports an academic paper named 'benchmark study for welding gun fault prediction'. <strong>Feature name and explanation:</strong> c1 : Electrode cap offset; c2 : Electrode force; c3 : Electrode position; c4 : Force build-up; c5 : Balance pressure; c6 : Friction; c7 : Maximum aperture; c8 : Maximum electrode force; c9 : Mtart friction; c10 : US2; c11 : Welding point count; c12 : Position count; c13: Setpoints of counterbalance pressure; c14: Setpoints of electrode force; c15 : Setpoints of electrode position; c16: Setpoints of sheet thickness; c17 : Setpoints of velocity;<br> c18: Setpoints of force build-up;<br> c19 : Offset value in robot. <strong>Machine Learning Task:</strong><br> This dataset is suitable for a time series forecasting task, where machine learning models can be trained to predict future welding parameters based on the provided welding parameters time series in history. <strong>Code for quick start:</strong> https://zenodo.org/record/7655025 If you want to have an overview of the data before downloading all of it, you can download only the files with the word "Damo" in the file name.
