Title:
WELDING SYSTEM, WELDING METHOD, WELDING ASSISTING DEVICE, PROGRAM, LEARNING DEVICE, AND TRAINED MODEL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/080015
Kind Code:
A1
Abstract:
This welding system comprises: a welding device, various different types of a plurality of sensors which detect an event according to welding performed by a welding device; and an estimation unit which uses a trained model that is pre-generated by machine-learning by taking, as input data, a plurality of pieces of data for learning obtained by detecting events according to welding by means of the same types of sensors as the plurality of sensors, and, as training data, labels representing whether the welding is normal or abnormal, thereby estimating an abnormality of the welding performed by the welding device from a plurality of pieces of detection data generated by the plurality of sensors.
