METHOD FOR INSPECTING WELDING QUALITY AND WELDING ROBOT SYSTEM

摘要

The present invention relates to a welding quality inspection method, and a welding robot system. The welding quality inspection method of the present invention comprises: a step of measuring a welding electricity value supplied to a welding robot during a process where the welding robot performs welding to a welded object; a step of generating a measurement waveform where the welding electricity value supplied to the welding robot varies in accordance with a welding time using the measured welding electricity value; a step of acquiring inspection data by comparing a normal waveform to the welded object with the measured waveform; and a step of acquiring an inspection value to a welding quality by giving a weighted value to each inspection item to the inspection data, and then summing a given weighted value based on learning data to the welding quality.
