Los ntawm cov teeb meem yav dhau los ntau, peb tau kawm cov yam ntxwv ntawm high-frequency vuam cov txheej txheem ntsig txog yam, qhov teeb meem no peb suav sau cov txheej txheem welding. Nyob rau hauv high zaus welding, lub zog ntawm vuam ceev ntawm vuam cov txheej txheem yuav tsum tau xav txog nyob rau hauv extrusion yob tsim cov khoom, cov yam ntxwv ntawm cov khoom, vuam fais fab vuam, vuam zaus cov ntsiab lus thiab vuam ceev cov ntsiab lus, Peb tuaj yeem xaus tias lub hom phiaj tseem ceeb ntawm vuam txheej txheem yog tswj ob lub ntsiab lus: qhov loj ntawm tshav kub cuam tshuam cheeb tsam (qhov ntim ntawm cov khoom siv ua kom sov hauv cheeb tsam extrusion) thiab lub sijhawm tso cua sov ntawm thaj tsam cuam tshuam tshav kub.
1. Qhov loj me ntawm cov tshav kub cuam tshuam
Nyob rau hauv cov txheej txheem ntawm cov hlau ntom vuam ntau, qhov loj ntawm cov tshav kub cuam tshuam cheeb tsam ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom lag luam vuam, uas yog qhov tseem ceeb heev; Yog hais tias lub tshav kub cuam tshuam cheeb tsam tsawg dhau, lub weld fusion tsis txaus thiab vuam tsis muaj feem cuam tshuam. Tsuas yog tsim qhov loj me ntawm cov tshav kub cuam tshuam tuaj yeem txais cov khoom haum haum thiab cov khoom tsim nyog.
2. Lub sijhawm cua sov
Hauv qhov chaw siab vuam, qhov ntev ntawm lub sijhawm cua sov yog qhov cuam tshuam ncaj qha cuam tshuam rau microstructure cov yam ntxwv ntawm cov cua sov cuam tshuam cheeb tsam (HAZ), uas tseem yog qhov tseem ceeb heev. Qhov ntev ntawm lub sijhawm cua sov muaj qhov cuam tshuam loj ntawm cov qauv pob kws ntawm cov khoom hauv thaj chaw melting. Cov qauv tsim nyog thiab cov kav dej thermal yog qhov tseem ceeb kom ntseeg tau tias lub weld microstructure piv nrog lub hauv paus hlau, Ntau zaus vuam yuav tsum xav tias microstructure ntawm lub weld zoo dua li ntawm cov hlau puag, uas yuav tsum tau tias lub microstructure thiab cov yam ntxwv ntawm lub weld yuav tsum tau lees tias. Yog li ntawd, ntau qhov vuam feem ntau yuav tsum muaj qee qhov vuam nrawm, uas yuav tsum tsis txhob qis dhau. Yog hais tias lub sijhawm cua sov ntev dhau lawm, nws yuav tsis tsuas yog cuam tshuam qhov loj ntawm lub tshav kub cuam tshuam cheeb tsam, tab sis kuj cuam tshuam qhov loj me ntawm cov nplej, uas ua rau cov noob nplej loj hlob, cuam tshuam rau kev ua haujlwm ntawm lub weld, uas tej zaum yuav pom muaj qhov tsis zoo hauv qee qhov kev ua haujlwm weld kev sim Yog lawm, yog tias lub sijhawm cua sov yog luv heev, nws yuav ua rau vuam txias yog tias nws tsis muaj cua sov kom huv, uas ua rau nws ua tsis tiav cov vuam nyhuv. Yog li no, lub sijhawm cua sov kuj yog tus yuam sij.
