Cov khoom siv feem ntau muaj chaw vuam thiab vuam vuam.
① Kev tsom iav
Hnov vuam yuav muab faib ua ob hom, ib leeg-ob tog thiab ob tog, tib yam li daim duab 1-1. Thaum ultrasonic kev co lub zog muaj kev nthuav qhia tsuas yog dhau ntawm sonotrode sab sauv, nws yog ib leeg-ib tog chaw vuam (a); thaum nws qhia los ntawm lub sab sauv thiab qis sonotrode, ntsig txog, nws yog ob-sided chaw welding (b). Tam sim no qhov feem ntau siv yog ib leeg ib tog txhuas-hauv qhov chaw vuam.

② leeg vuam
Cov xaim hluav taws xob ultrasonic tau xa mus rau qhov chaw ua haujlwm dhau los ntawm lub suab uas muaj lub suab zoo uas tig thiab tsim cov hlau txuas txuas nrog. Lub tshuab kev co tuaj yeem muab faib ua lub suab ntev ntev, kev khoov txav kev co thiab torsion raws li lub xeev kev co ntawm lub disc-puab lub suab ncej.
Peb yam ntawm kev co. Thawj ob yog siv ntau dua, raws li qhia hauv daim duab 1-2. Qhov kev co ntawm kev taw qhia ntawm cov duab tawm ntawm sonotrode yog txiav mus rau qhov kev taw qhia vuam.

Girth vuam
Lub voj voos ntiv nplhaib vuam viav vias tuaj yeem siv tau los tsim kev kaw vuam vuam ib zaug. Lub workpiece yuav tsum tau welded yog clamped nruab nrab ntawm lub nplhaib sab saud thiab qis suab ncej, thiab lub siab zoo li qub tau thov rau qhov haujlwm ntawm qhov chaw hauv lub axial.
Girth vuam siv lub zog ua kom sib dhos. Vim tias thaj tsam loj ntawm lub sijhawm ib-vuam sib dhos hauv qhov txuas girth thiab qhov xav tau ntawm lub zog loj rau cov tswv yim, qhov kev cuam tshuam tsav tsheb sib xyaw ntawm ntau cov hloov tsheb feem ntau siv. Lub tshuab hluav taws xob tsaj plaws los ntawm ob lub zog ntawm cov khoom siv sib xyaw nrog qhov sib txawv theem ntawm 180 °, uas thawb thiab rub tawm los ua kom muaj kev co. Yog li cov tshuab soldering no haum rau lub ntim ntawm cov khoom siv hluav taws xob me me.
④ xaim ua ke
Cov khoom siv hlau tsis tuaj yeem suav tau tias yog qhov txuas ntxiv ntawm qhov chaw vuam hlau. Nws yog qhov zoo tshaj plaws los siv linear sab sauv sonotrode los yog mus rau superimpose ntau cov nqaij ntawd vuam sonotrodes ua ke los ua qhov ncaj vuam sib txuas rau hauv lub voj vuam rau cov vuam txuas uas yuav tsum muaj kab sib dhos.
