usm是指超声加工。

超声加工是利用超声频作小振幅振动的工具，并通过它与工件之间游离于液体中的磨料对被加工表面的捶击作用，使工件材料表面逐步破碎的特种加工，英文简称为 USM。超声加工常用于穿孔、切割、焊接、套料和抛光。

超声波随着技术的发展越来越为人们所应用，他通过自身的一些特性一步步奠定自己在切削、拉丝模、深小孔加工等的地位。超声加工在几十年里的到了迅猛发展，尤其是在难加工材料领域解决了很多关键的工艺问题，取得了良好的效果。

工作原理

通过上焊件把超声能量传送到焊区，由于焊区即两个焊接的交界面处声阻大，因此会产生局部高温。又由于塑料导热性差，一时还不能及时散发，聚集在焊区，致使两个塑料的接触面迅速熔化，加上一定压力后，使其融合成一体。

当超声波停止作用后，让压力持续，有些许保压时间，使其凝固成型，这样就形成一个坚固的分子链，达到焊接的目的，焊接强度能接近于原材料本体强度。
