Resistance cua sov nyob rau hauv nruab nrab zaus Inverter Spot Vuam Tshuab thiab nws cuam tshuam dab tsi?

Resistance cua sov yog txheej txheem tseem ceeb hauv nruab nrab zaus inverter qhov chaw vuam tshuab, qhov twg cov hluav taws xob tsis kam ntawm cov khoom ua haujlwm ua kom sov thaum lub sijhawm ua haujlwm vuam.Tsab ntawv xov xwm no tsom mus tshawb txog cov txheej txheem ntawm kev ua kom sov thiab sib tham txog ntau yam uas cuam tshuam rau nws cov txiaj ntsig thiab kev cuam tshuam ntawm cov txheej txheem vuam.

1. Resistance Heating Mechanism: Nyob rau hauv nruab nrab zaus inverter qhov chaw vuam tshuab, qhov kev nkag siab ntawm cov hluav taws xob tam sim no los ntawm cov khoom ua haujlwm ua rau muaj kev cuam tshuam hauv kev sib koom ua ke.Qhov kev tiv thaiv no hloov hluav taws xob hluav taws xob mus rau hauv tshav kub, ua rau cov cua sov hauv cheeb tsam ntawm qhov chaw vuam.Cov cua sov tsim los ntawm cov cua sov ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo fusion thiab ua kom muaj zog weld nugget.
2. Cov yam ntxwv cuam tshuam rau cov cua kub tsis kam: Ntau yam cuam tshuam rau kev ua haujlwm ntawm cov cua sov hauv nruab nrab zaus inverter qhov chaw vuam tshuab.Cov xwm txheej no suav nrog: a.Hluav taws xob Conductivity: Cov hluav taws xob conductivity ntawm cov khoom siv ua haujlwm cuam tshuam rau qhov tsis kam thiab, yog li, cov cua sov tsim tawm.Cov ntaub ntawv uas muaj hluav taws xob ntau dua kev ua haujlwm qis dua thiab zoo li ua kom muaj cua sov tsawg dua piv rau cov khoom siv nrog qis conductivity.b.Khoom Thickness: Thicker workpieces pom muaj zog dua vim txoj kev ntev dua tam sim no, ua rau muaj cua sov ntau ntxiv thaum lub sij hawm vuam.c.Tiv tauj Resistance: Qhov zoo ntawm hluav taws xob tiv tauj ntawm cov electrodes thiab workpieces ho cuam tshuam rau cov cua sov ua hauj.Kev sib cuag tsis zoo ua rau muaj kev tiv thaiv ntau dua ntawm electrode-workpiece interface, uas ua rau txo cov cua sov hloov thiab muaj feem cuam tshuam rau qhov zoo ntawm vuam.d.Vuam tam sim no: Qhov loj ntawm qhov vuam tam sim no ncaj qha cuam tshuam cov cua sov uas tsim los ntawm cov cua sov ua haujlwm.Cov hluav taws xob siab dua ua kom muaj cua sov ntau dua, thaum cov hluav taws xob qis tuaj yeem ua rau cov cua sov tsis txaus thiab tsim cov vuam tsis txaus.e.Vuam Lub Sijhawm: Lub sijhawm ntawm kev ua haujlwm vuam kuj cuam tshuam rau cov cua sov ua haujlwm.Lub sijhawm vuam ntev tso cai rau cov cua sov ntau dhau los ua kom muaj kev sib txuas zoo dua thiab muaj zog welds.Txawm li cas los xij, lub sijhawm vuam ntev ntev tuaj yeem ua rau overheating thiab muaj peev xwm puas tsuaj rau cov khoom ua haujlwm.f.Electrode Force: Lub zog siv ntawm cov electrodes cuam tshuam rau kev sib cuag hluav taws xob thiab, tom qab ntawd, cov cua sov ua haujlwm.Tsim nyog electrode quab yuam ua kom muaj kev sib cuag zoo thiab hloov cov cua sov kom zoo, ua rau kev txhim kho weld zoo.
3. Impact of Resistance Heating: Resistance cua sov muaj qhov cuam tshuam ncaj qha rau cov txheej txheem vuam thiab qhov ua tau zoo ntawm vuam.Cov teebmeem tseem ceeb muaj xws li: a.Thaum tshav kub kub Generation: Resistance cua sov muab qhov tsim nyog thermal zog los yaj cov ntaub ntawv workpiece, yooj yim fusion thiab tsim ib tug weld nugget.b.Material Softening: Cov cua kub hauv cheeb tsam los ntawm cov cua sov ua haujlwm softens cov ntaub ntawv ua haujlwm, tso cai rau cov yas deformation thiab txhawb kev sib koom ua ke ntawm kev sib koom ua ke.c.Heat Affected Zone (HAZ): Cov cua sov tsim tawm thaum lub sij hawm cua sov kuj cuam tshuam rau cov khoom siv nyob ib puag ncig, ua rau muaj kev cuam tshuam ntawm tshav kub kub (HAZ) uas muaj kev hloov pauv microstructure thiab txhua yam khoom.d.Weld Penetration: Tus nqi ntawm cov cua sov tsim los ntawm cov cua kub tsis kam cuam tshuam qhov tob ntawm weld nkag.Kev tswj kom zoo ntawm cov hluav taws xob hluav taws xob kom paub meej txaus nkag mus yam tsis muaj ntau dhau yaj-los ntawm kev kub hnyiab-los ntawm.

Cov ntsiab lus: Resistance cua sov yog ib qho txheej txheem tseem ceeb hauv nruab nrab zaus inverter qhov chaw vuam tshuab, ua lub luag haujlwm tseem ceeb hauv kev ua tiav kom zoo fusion thiab tsim cov welds muaj zog.Nkag siab txog cov txheej txheem ntawm kev ua kom sov thiab xav txog cov kev cuam tshuam, xws li hluav taws xob conductivity, cov khoom tuab, kev tiv thaiv kev tiv thaiv, vuam tam sim no, vuam lub sij hawm, thiab electrode quab yuam, ua kom muaj kev tswj xyuas zoo ntawm cov txheej txheem vuam thiab ua kom lub vuam zoo thiab kev ua haujlwm zoo.Los ntawm kev ua kom cov cua sov ua kom zoo, cov tuam ntxhab tuaj yeem txhim kho qhov ua tau zoo, kev ntseeg tau, thiab sib xws ntawm qhov chaw vuam ua haujlwm hauv ntau daim ntawv thov kev lag luam.
