Analyzing method of spot welded portion, analyzing program of spot welded portion, recording medium and analyzing apparatus of spot welded portion

Abstract

An analyzing method of a spot welded portion, includes: acquiring bar elements as the spot welded portion; extracting other bar elements existing at a periphery of a target bar element which is targeted among the acquired bar elements; determining whether or not there is a bar element which shares the same end point with the target bar element among the extracted bar elements; determining that the target bar element and the bar element which shares the same end point with the target bar element are a three-layer spot welded portion when it is determined that there is the bar element which shares the same end point with the target bar element; and determining whether or not there is a bar element whose distance between elements with the target bar element is within a predetermined distance among the extracted bar elements when it is determined that there is not the bar element which shares the same end point with the target bar element, and determining that the target bar element and the extracted bar element are not the three-layer spot welded portion when it is determined that there is not the bar element within the predetermined distance.
