Cov nyhuv ntug yog ib qho tshwm sim tshwm sim hauv nruab nrab zaus inverter qhov chaw vuam tshuab.Kab lus no tshawb txog cov laj thawj tom qab qhov tshwm sim ntawm cov nyhuv ntug thiab sib tham txog nws qhov cuam tshuam hauv qhov chaw vuam ua haujlwm.
Tam sim no Concentration:
Ib qho ntawm cov laj thawj tseem ceeb ntawm cov nyhuv ntug yog qhov concentration ntawm tam sim no nyob ze ntawm ntug ntawm lub workpiece.Thaum lub sij hawm qhov chaw vuam, qhov tam sim no nyiam mloog ntawm cov npoo vim muaj hluav taws xob ntau dua hauv cheeb tsam no.Qhov concentration ntawm tam sim no ua rau cov cua kub tsis sib xws thiab vuam, ua rau cov nyhuv ntug.
Electrode Geometry:
Cov duab thiab tsim ntawm cov electrodes siv nyob rau hauv qhov chaw vuam kuj tuaj yeem ua rau cov nyhuv ntug.Yog hais tias cov lus qhia electrode tsis zoo sib xws lossis yog tias muaj qhov sib txawv tseem ceeb ntawm cov electrodes thiab cov npoo ntawm qhov chaw ua haujlwm, qhov kev faib tawm tam sim no yuav tsis sib xws.Qhov kev faib tsis sib npaug no ua rau cov cua sov hauv cheeb tsam thiab muaj feem ntau dua ntawm cov nyhuv ntug.
Hluav taws xob conductivity ntawm workpiece:
Cov hluav taws xob conductivity ntawm cov khoom siv ua haujlwm tuaj yeem cuam tshuam qhov tshwm sim ntawm ntug nyhuv.Cov ntaub ntawv uas muaj cov conductivity qis dua yuav ua rau pom cov txiaj ntsig zoo dua piv rau cov khoom siv hluav taws xob.Cov khoom siv hluav taws xob qis dua muaj hluav taws xob ntau dua, uas ua rau cov concentration tam sim no thiab cua sov tsis sib xws nyob ze ntawm cov npoo.
Thickness ntawm workpiece:
Lub thickness ntawm lub workpiece plays lub luag hauj lwm nyob rau hauv qhov tshwm sim ntawm ntug nyhuv.Thicker workpieces tuaj yeem ua rau muaj qhov cuam tshuam loj dua vim qhov ntev ntawm txoj kab txuas ntxiv rau tam sim no ntws.Txoj kev ntev dua ua rau muaj hluav taws xob ntau dua ntawm cov npoo, ua rau tam sim no concentration thiab tsis sib xws.
Electrode Siab:
Tsis txaus electrode siab yuav exacerbate ntug nyhuv.Yog hais tias cov electrodes tsis ua kom zoo sib cuag nrog lub workpiece nto, muaj peev xwm yuav muaj hluav taws xob ntau dua ntawm cov npoo, ua rau tam sim no concentration thiab tsis sib xws cua sov.
Cov nyhuv ntug hauv nruab nrab zaus inverter qhov chaw vuam tshuab yog feem ntau tshwm sim los ntawm qhov tam sim no concentration ze ntawm cov npoo ntawm lub workpiece.Cov yam ntxwv xws li electrode geometry, hluav taws xob conductivity ntawm lub workpiece, thickness, thiab electrode siab tuaj yeem cuam tshuam qhov hnyav ntawm ntug nyhuv.Kev nkag siab txog cov laj thawj no yog qhov tseem ceeb rau kev ua kom zoo dua cov txheej txheem vuam thiab txo qhov cuam tshuam ntawm cov nyhuv ntug kom ua tau raws li qhov zoo sib xws thiab qhov chaw zoo welds.
