Tam sim no qhov ntom ntom yog ib lub tswv yim tseem ceeb hauv thaj tsam ntawm lub taub qab vuam tshuab. Nws ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau zoo thiab zoo ntawm cov txheej txheem vuam. Qhov tsab xov xwm no aims los piav qhia txog qhov tseem ceeb ntawm tam sim no ceev nyob rau hauv lub taub qab vuam tshuab, nws xam, thiab nws cov cuam tshuam rau weld yam ntxwv.
- Lub ntsiab lus ntawm Current Density: Tam sim no qhov ceev yog hais txog tus nqi ntawm cov hluav taws xob tam sim no ntws los ntawm ib qho chaw hla ntu ntawm lub workpiece thaum lub sij hawm vuam txheej txheem. Nws feem ntau ntsuas hauv amperes ib square millimeter (A / mm²). Kev nkag siab thiab tswj qhov ceev tam sim no yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws.
- Kev xam qhov ceev tam sim no: Txhawm rau xam qhov ceev tam sim no, faib cov vuam tam sim no (hauv amperes) los ntawm qhov chaw hla ntawm qhov chaw ua haujlwm (hauv square millimeters) ntawm qhov chaw vuam. Qhov kev suav no ua rau tus nqi tam sim no ntom ntom, uas yog qhov tseem ceeb tsis zoo uas cuam tshuam rau lub vuam lub zog, qhov tob tob tob, thiab qhov kub ntawm qhov chaw cuam tshuam.
- Kev cuam tshuam rau Weld yam ntxwv: Tam sim no qhov ntom ntom cuam tshuam rau qhov tshwm sim ntawm cov txheej txheem vuam. Lub siab ceev tam sim no tuaj yeem ua rau muaj kev nkag mus tob dua, kev sib txuas nrawm dua, thiab muaj cua sov ntau ntxiv. Txawm li cas los xij, qhov ceev tam sim no ntau dhau tuaj yeem ua rau muaj kev nkag mus rau ntau dhau, cuam tshuam, thiab muaj peev xwm ua rau muaj kev cuam tshuam ntawm qhov sib koom ua ke.
- Optimizing Current Density: Ua kom muaj qhov tsim nyog tam sim no yog qhov tseem ceeb rau kev tau txais cov khoom zoo. Cov neeg ua haujlwm vuam yuav tsum xav txog ntau yam, xws li cov khoom siv, tuab, thiab kev sib koom ua ke, txhawm rau txhim kho qhov ceev tam sim no. Los ntawm kev kho cov vuam tam sim no thiab electrode quab yuam, welders tuaj yeem kho qhov ceev tam sim no kom ua tiav cov yam ntxwv xav tau.
- Thaum tshav kub kub tswj thiab Efficiency: Tswj qhov ceev tam sim no yog ib qho tseem ceeb rau kev tswj cov cua sov input thaum vuam. Kev tswj xyuas kom zoo tam sim no ua kom ntseeg tau tias qhov zoo ntawm cov cua sov yog siv los tsim kom muaj zog thiab zoo sib xws uas tsis ua rau overheating lossis underheating ntawm lub workpiece.
- Kev cuam tshuam ntawm Weld Strength: Tam sim no qhov ntom ntom ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov vuam lub zog thiab kev ncaj ncees. Qhov tsim nyog tam sim no ceev kom zoo fusion thiab metallurgical bonding ntawm lub hauv paus hlau, uas ua rau ib tug txhim khu kev qha thiab ruaj weld sib koom.
Hauv kev xaus, qhov ceev tam sim no yog qhov tseem ceeb hauv cov tshuab vuam taub qab uas cuam tshuam ncaj qha rau qhov zoo thiab ua haujlwm ntawm cov txheej txheem vuam. Kev nkag siab txog lub tswv yim ntawm qhov ceev tam sim no thiab nws cov kev cuam tshuam ntawm cov yam ntxwv ntawm vuam ua rau cov neeg ua haujlwm vuam kom paub txiav txim siab thiab ua tiav cov txiaj ntsig zoo. Los ntawm kev ua tib zoo tswj qhov ceev tam sim no, cov welds tuaj yeem tsim cov vuam zoo uas ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam kev siv thiab kev lag luam.
