Description
本発明者等は、このようにリチウムイオン電池ケース用の素材として優れているA1000系アルミニウム材の利点を生かしつつ、これをパルスレーザ溶接により溶接したときの欠点を解消できる素材を開発すべく、種々実験研究した。その結果、素材の溶融時(660〜750℃)における粘性が、パルスレーザの不規則ビードである異常部22の発生に大きな影響を与えていることを見出した。

次に、別の観点に基づく本願第2発明について説明する。前述のごとく、パルスレーザ溶接における異常部の発生は、素材の溶融時(660〜750℃)における粘性が大きく影響している。この液相における粘性は、パルスレーザ溶接後の溶接部におけるポロシティ欠陥の発生度と関連する。
