金属焊接（超声）
一种通过以剪切（擦刷）模式施加超声振动来连接两个金属零件的工艺（图 1 引自 Al‑Sarraf[1]）。超声振动会将两个零件界面处的表面氧化物和污染物排挤开，从而实现紧密的金属与金属接触，进而形成焊缝。焊接温度相对较低，且不涉及熔化。详见 …
Metal welding (ultrasonic)
A process of joining two metal parts by applying ultrasonic vibration in a shear (scrubbing) mode (figure 1 from Al‑Sarraf[1]). The ultrasonic vibration displaces the surface oxides and contaminates at the interfaces of the two parts, thereby allowing intimate metal-to-metal contact from which the weld occurs. The weld temperature is relatively low and does not involve melting. Details ...
