接合部の機能性評価によるスポット溶接条件の最適化

抄録

In　many　cases,　the　strength　of　material　after　welding　is　used　to　show　the　quality　of　spot　welding. But　this　type　of　evaluation　leads　to　reliance　on　destructive　tests　and　is　difficult　to　observe　the　situation after　the　welding　is　completed.　Therefore,　evaluation　is　made　either　by　using　some　substitute characteristics　or　by　periodical　checks　during　production.　ln　this　study,　a　welding　process　was optimized　for　the　reduction　of　maintenance　costs　for　a　welding　process　by　evaluating　the　function　of the　welded　parts.
