FABRICATED-IN-PLACE INSERTS TO RECEIVE SELF-PIERCING RIVETS |
摘要 |
One or more ductile metal inserts may be selectively incorporated into articles of limited ductility, including castings and molded polymers. The inserts are positioned at joint locations for joining of the article to other articles using self-piercing riveting (SPR). The inserts are of suitable ductility, thickness and strength to receive and retain self-piercing rivets and enable a strong riveted joint between the article and a second article. In an embodiment the articles are magnesium alloy castings formed by any of sand casting, die casting and semi-solid metal casting. The chemical composition of the insert may be informed by the anticipated corrosive environment of the joint and the casting temperature of the magnesium alloy. For magnesium alloy castings which may be exposed to corrosive environments, aluminum alloy inserts are preferred.
