Abstract
Description
本発明に係る溶接不良の検査方法において、電極組立体のサンプルは、電極組立体に形成された電極タブに電極リードを溶接して製造される。
電極組立体のサンプルが製造されると、上記電極組立体のサンプルに対して、電極タブと電極リードとの間の溶接部分の溶接強度、即ち、引張強度、ねじり強度および剥離強度を測定する。本発明に係る溶接不良の検査方法において、溶接強度は外力の方向によって2種類以上が測定され得る。
電極組立体のサンプルに対して、引張強度、ねじり強度および剥離強度が測定されると、上記引張強度、ねじり強度および剥離強度と溶接不良の有無との相関関係を導出する。ここで、相関関係とは、引張強度、ねじり強度および剥離強度の数値に応じた溶接不良の有無が示す傾向性を意味する。
上記引張強度、ねじり強度および剥離強度と溶接不良の有無との相関関係を導出し、そこから上記溶接不良の有無を判定するための基準値を導出する。この基準値は上記データベースから導出される。また、引張強度、ねじり強度および剥離強度のそれぞれに対する全ての基準値が導出される。
