Abstract
Description
本実施の形態について、図1から図9を用いて説明する。図1は、接合部材であって、本開示に係る第1の同種系金属材である第1の材料1と本開示に係る第2の同種系金属材である第3の材料3と、異種材の第2の材料2との接合構造を示している。ここで、図4は、上板としての第1の材料1が円形状である構造のものを説明するための図である。図5は、上板としての第1の材料1が角形状である構造のものを説明するための図である。そして、図4および図5に示すI-I断面が、図1の断面位置に対応する。
次に、本実施の形態2について、図2を用いて説明する。実施の形態1と重複する部分は説明を省略する。実施の形態1と異なる点は、第1の材料1には第1の突起部4が有るが、第3の材料3の形状に第2の突起部5が無い点である。第3の材料3に第2の突起部5の加工が無いことで材料の加工費用の削減が可能であり、第1の材料1と第2の材料2と位置が第3の材料3の位置ズレに影響されない利点がある。この場合も、実施の形態1と同様に、第1の貫通穴11の板厚方向の第1の材料と第3の材料との隙間である第2のギャップ8を設けてアーク溶接することで、溶接部16の凝固収縮が圧縮力18となり、第1の材料1と第3の材料3との間に挟まれた第2の材料2を圧縮固定する。
次に、本実施の形態3について、図10~図12を用いて説明する。実施の形態1や2と重複する部分は説明を省略する。実施の形態1と異なる点は、板厚方向からアーク溶接される第1の突起部4および第2の突起部5に対する溶接領域において、例えば、アーク15が照射される側の第1の材料1の第1の突起部4の中央の一部分に、アーク15が照射される溶接領域より小さい第2の貫通穴6(本開示に係る第2の貫通部の一例)を設け、第1の突起部4の形状を中央部の一部に穴が開いた鍔状とした点である。この第2の貫通穴6により、上板である第1の材料1をアーク熱で穴開きを作り、第3の材料3と溶融接合させる必要がなく、溶接ワイヤの溶融金属で第1の材料1と第3の材料3との溶融を促進させて、第1の突起部4および第2の突起部5の対向面を互いに強固に溶融接合させることができるものである。
次に、本実施の形態4について、図13を用いて説明する。実施の形態1と重複する部分は説明を省略する。実施の形態1と異なる点は、第1の材料1の第1の突起部4や第3の材料3の第2の突起部5に接し合う箇所より板厚方向に直交する方向の外側または、異種材の第1の貫通穴11より板厚方向に直交する方向の外側で、同種系金属材の板厚方向に貫通するに複数個の排出穴17または排出溝を設けたことである。排出穴17および排出溝は、本開示に係る排出部の一例である。
従来の異材接合用部材としてのリベットは、かしめ加工時およびスポット溶接時に異種材料の一部が変形して移動するスペースの確保及びスポット溶接時の電極の位置ズレ等による異種材の陥没等を防いで締結力低下の抑制を可能とするために、R形状の面取りや環状溝等の複雑なリベット形状が必要であった。
