SPOT WELDING SECTION ANALYSIS METHOD, SPOT WELDING SECTION ANALYSIS PROGRAM, STORAGE MEDIUM AND SPOT WELDING SECTION ANALYSIS DEVICE

摘要

A method of analyzing a spot welded portion includes a step of obtaining a burr element as a spot welded portion, a step of extracting another burr element around the noted burr element, which is one of the obtained burr elements, A step of determining whether or not a burr element sharing the same end point exists; and a step of determining whether or not there exists a burr element sharing the same end point as the noted burr element, A step of judging that a burr element sharing three or more burr elements overlapped with each other is determined to be a spot welded portion that overlaps three burr elements sharing the same point; and a step of, when it is determined that there is no burr element sharing the same end point as the noted burr element, It is determined whether or not there is a burr element whose distance between the elements is within a predetermined distance. If the burr element is within a predetermined distance And when it is determined that there is no spot welded portion, it is determined that the spot burr element is not a spot welded portion in which three burr elements are overlapped with each other.
