Nyob rau hauv ib qho kev tiv thaiv-spot teeb-up txhua yam uas ua rau tam sim no lossis electrode quab yuam wander yuav tam sim ntawd hloov nugget loj lossis lub zog.
a) Cov khoom siv vuam tsis ruaj khov-tam sim no cov zis
Aging IGBT modules, tsis muaj zog-qhov chaw tsis zoo lossis kev coj tus cwj pwm tsis zoo ntawm pawg tswj hwm tag nrho cia cov mem tes tam sim no hloov pauv, yog li kev sib koom ua ke hloov pauv ntawm vuam mus rau vuam.
b) Hnav los yog oxidised electrodes
Cov lus qhia uas yog nceb, kab mob los yog tawm ntawm qhov chaw muab qhov chaw sib txawv thiab qhov siab hneev taw, yog li qhov chaw me me tawg.
c) Lub tog raj kheej / servo quab yuam drift
Txhua qhov kev hloov pauv hauv forging quab yuam hloov cov kab nrib pleb; tib lub sijhawm tam sim no tuaj yeem nkag mus tsawg lossis ntau dhau.
d) Cov cua txias tsis txaus
Cov cua txias-dej kub los yog thaiv Circuit Court ua kom sov lub electrodes thiab tshuab hardware, sib txawv bulk kuj thiab muab erratic me ntsis.
Kev khiav hauj lwm los yog teeb tsa tsis raug yog ntau zaus tshaj li qhov koj xav
Ntau qhov 'phem' tsis yog tshwm sim los ntawm tus welder tawg tab sis los ntawm kev hla cov ntsiab lus hauv cov txheej txheem lossis tuav.
a) Lub sij hawm vuam tsis sib haum
tam sim no, qhov hluav taws xob, lub sijhawm lossis lub zog uas tawm los ntawm ib kauj ruam yuav ua rau tawg-tshwj xeeb tshaj yog thaum daim ntawv tuab lossis txheej txheej hloov thiab lub sijhawm tsis hloov kho.
b) Electrodes tsis hnav lossis hloov ntawm lub voj voog
Cov neeg ua haujlwm feem ntau tsis quav ntsej txog kev saib xyuas, tab sis qhov chaw-weld repeatability nyob ntawm yuav luag tag nrho ntawm cov duab thiab kev huv.
