Resistance chaw vuam yog txheej txheem siv dav hauv kev tsim khoom thiab kev tsim kho kev lag luam rau kev koom nrog cov khoom siv hlau.Nws tso siab rau lub hauv paus ntsiab lus ntawm hluav taws xob tsis kam ua kom muaj cua sov ntawm cov ntsiab lus sib txuas ntawm ob qhov chaw hlau, uas tom qab ntawd fused ua ke.Txawm li cas los xij, qhov ua tau zoo ntawm cov txheej txheem vuam no yog cuam tshuam los ntawm ntau yam thermal yam hauv lub tshuab vuam.Hauv tsab xov xwm no, peb yuav tshawb txog cov ntsiab lus tseem ceeb uas cuam tshuam rau thermal yam ntawm qhov chaw vuam tshuab.
- Tam sim no Flow:Lub hauv paus tseem ceeb cuam tshuam rau qhov thermal nam ntawm qhov chaw vuam yog qhov ntws ntawm hluav taws xob tam sim no.Thaum lub siab tam sim no dhau los ntawm cov khoom siv hlau raug welded, nws ntsib qhov tsis kam, ua rau lub cim ntawm cov cua sov.Qhov kev siv ntawm tam sim no thiab nws lub sijhawm ua rau muaj feem cuam tshuam rau cov cua sov uas tsim tawm.
- Electrode Khoom:Cov khoom siv ntawm vuam electrodes plays lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob thiab hloov pauv.Electrodes feem ntau yog tsim los ntawm tooj liab alloys vim lawv zoo heev conductivity thiab kub tsis kam.Kev xaiv electrode kom zoo ua kom muaj hluav taws xob zoo thiab hloov mus rau cov khoom ua haujlwm.
- Electrode Geometry:Cov duab thiab qhov loj ntawm cov electrodes txiav txim siab faib cov cua sov thaum vuam.Cov qauv siv hluav taws xob tuaj yeem tsim kho kom ua tiav cov qauv cua sov tshwj xeeb, xws li taw tes vuam lossis seam vuam.Cov electrode geometry cuam tshuam qhov concentration ntawm tshav kub ntawm qhov chaw vuam.
- Electrode quab yuam:Lub zog siv los ntawm cov electrodes ntawm lub workpieces yog qhov tseem ceeb rau kev ua tiav cov vuam muaj zog.Nws kuj cuam tshuam cov thermal nam los ntawm kev tswj kev tiv thaiv kev tiv thaiv thiab, tom qab ntawd, lub tshav kub generated.Kev quab yuam electrode kom zoo ua kom muaj cua sov zoo ib yam.
- Lub sijhawm vuam:Lub sijhawm uas tam sim no ntws los ntawm cov khoom ua haujlwm, hu ua lub sijhawm vuam, yog qhov tseem ceeb hauv kev tswj xyuas thermal.Lub sijhawm vuam ntev tuaj yeem ua rau muaj cua sov ntau dhau, uas ua rau deformation lossis hlawv-los ntawm cov ntaub ntawv.
- Cooling Mechanisms:Ntau qhov chaw vuam tshuab siv cov tshuab cua txias los tiv thaiv overheating.Cov txheej txheem no pab tswj cov cua sov zoo ib yam thaum lub sijhawm ua haujlwm txuas txuas ntxiv.Dej txias, piv txwv li, pab dissipate cua sov los ntawm cov electrodes.
- Khoom siv:Hom thiab thickness ntawm cov ntaub ntawv raug welded kuj cuam tshuam rau thermal yam ntawm cov txheej txheem.Cov hlau sib txawv thiab cov hlau sib txawv muaj qhov sib txawv ntawm cov hluav taws xob tiv thaiv, conductivity, thiab melting cov ntsiab lus, yuav tsum tau kho nyob rau hauv vuam tsis.
- Welding Ib puag ncig:ambient kub thiab av noo tuaj yeem cuam tshuam tus cwj pwm thermal ntawm qhov chaw vuam.Cov xwm txheej hnyav yuav xav tau kev hloov kho rau cov vuam tsis sib xws kom tswj tau cov cua sov sib xws.
Hauv kev xaus, qhov chaw vuam tsis kam yog cov txheej txheem sib koom ua ke uas tso siab rau kev tswj xyuas meej ntawm thermal yam hauv lub tshuab vuam.Kev nkag siab thiab ua kom zoo dua cov yam tseem ceeb no yog qhov tseem ceeb rau kev ua tiav cov welds zoo, ua kom lub zog thiab ua haujlwm ntev ntawm cov khoom siv welded.Cov neeg tsim khoom thiab cov neeg ua haujlwm yuav tsum xav txog cov txheej txheem thermal no los tsim cov welds txhim khu kev qha thiab zoo ib yam hauv ntau daim ntawv thov kev lag luam.
