铆焊
一种将两个零件连接在一起的工艺：其中一个零件（塑料件）带有一个凸起，该凸起穿过第二个零件上的孔。（凸起通常为圆柱形，可为实心或空心；第二个零件常为金属。）随后，带有特殊成形端头的点焊变幅杆接触该塑料凸起并使其超声熔化，从而在凸起上形成一个头部，将两个零件机械地连接在一起。当两个零件由无法焊接的异种材料制成，或者只需实现一个零件相对于另一个零件的简单机械固定（即与分子结合相区别）时，超声铆焊可以替代焊接。
图 1 展示了一种铆焊构型。 其他构型见 Sonics[5] 和 Dukane[5]。

Staking
A process of joining two parts together where one part (the plastic part) has a protrusion that is inserted through a hole in the second part. (The protrusion is usually cylindrical, either solid or hollow. The second part is often metal.) A spot welding horn with a specially contoured tip then touches and ultrasonically melts the plastic protrusion, thereby forming a head on the protrusion which mechanically joins the two parts. Ultrasonic staking provides an alternative to welding when the two parts consist either of dissimilar materials which cannot be welded, or when simple mechanical retention of one part relative to another is adequate (i.e. as distinct from molecular bonding).
Figure 1 shows one staking configuration. For other configurations see Sonics[5] and Dukane[5].
Synonyms — heading, reforming, riveting
