Resistance chaw vuam yog txheej txheem siv dav hauv ntau yam lag luam, suav nrog tsheb, aerospace, thiab hluav taws xob. Cov txheej txheem no koom nrog ob lossis ntau daim hlau los ntawm kev siv cua sov thiab siab ntawm cov ntsiab lus tshwj xeeb. Qhov zoo ntawm qhov chaw weld yog qhov tseem ceeb rau kev ua haujlwm tag nrho thiab ua haujlwm ntev ntawm cov khoom tiav. Hauv tsab xov xwm no, peb yuav tshawb txog peb yam tseem ceeb uas cuam tshuam rau qhov chaw vuam thiab lawv qhov cuam tshuam rau cov txheej txheem vuam thiab cov khoom kawg.
- Tam sim no siv zog (Amperage)
Qhov kev siv tam sim no, ntsuas hauv amperes, yog ib qho tseem ceeb ntawm qhov chaw vuam. Nws txiav txim siab npaum li cas ntawm cov cua sov tsim ntawm qhov chaw vuam. Thaum qhov tam sim no tsawg dhau, cov cua sov tsis txaus yog tsim, ua rau cov welds tsis muaj zog thiab tsis tiav. Piv txwv li, ntau dhau tam sim no tuaj yeem ua rau overheating, ua rau hlawv-los ntawm kev puas tsuaj rau cov khoom ua haujlwm.
Yuav kom ua tiav qhov zoo tshaj plaws weld zoo, nws yog ib qho tseem ceeb los xaiv qhov tsim nyog tam sim no siv raws li cov khoom siv thiab thickness. Welding engineers thiab cov kws tshaj lij yuav tsum ua tib zoo xam thiab teeb tsa tam sim no kom ntseeg tau tias cov welds zoo ib yam thiab txhim khu kev qha.
- Lub sijhawm vuam
Lub sijhawm vuam, feem ntau ntsuas hauv milliseconds, yog lwm qhov tseem ceeb hauv qhov chaw vuam. Nws txiav txim siab ntev npaum li cas qhov tam sim no ntws los ntawm cov khoom ua haujlwm, cuam tshuam qhov loj thiab lub zog ntawm qhov vuam nugget - qhov melted thiab fused feem ntawm cov ntaub ntawv.
Lub sij hawm luv luv vuam yuav tsis muaj cua sov txaus los tsim kom muaj kev sib txuas zoo, thaum lub sij hawm ntev ntev tuaj yeem ua rau cov ntaub ntawv softening thiab txo lub zog vuam. Nrhiav qhov sib npaug yog qhov tseem ceeb rau kev ua tiav ib qho kev sib txuas nrog cov khoom xav tau.
- Siab (Electrode Force)
Siab, siv los ntawm vuam electrodes, plays lub luag haujlwm tseem ceeb hauv qhov chaw vuam. Nws coj cov workpieces mus rau hauv kev sib raug zoo, ua kom muaj kev sib cuag hluav taws xob zoo thiab txhawb kev hloov cua sov. Lub siab thov yuav tsum txaus los tuav cov ntaub ntawv ua ke thaum thiab tom qab vuam txheej txheem.
Kev tsis txaus siab tuaj yeem ua rau tsis zoo weld zoo, vim nws yuav ua rau muaj qhov sib txawv ntawm cov khoom ua haujlwm lossis kev nkag mus tsis txaus. Ntawm qhov tod tes, lub siab ntau dhau tuaj yeem deform lossis puas cov ntaub ntawv, ua rau tsis zoo rau tag nrho cov qauv kev ncaj ncees.
Hauv kev xaus, qhov zoo ntawm qhov chaw vuam zoo heev cuam tshuam los ntawm peb yam tseem ceeb: tam sim no siv, vuam lub sij hawm, thiab siab. Kev ntsuas qhov ntsuas no yog qhov tseem ceeb rau kev ua tiav cov welds uas ua tau raws li cov qauv tsim nyog rau lub zog, durability, thiab zoo li. Vuam tswv thiab engineers yuav tsum ua tib zoo xav txog cov xwm txheej no thiab txuas ntxiv saib xyuas thiab kho lawv kom ntseeg tau tias qhov ua tau zoo tshaj plaws ntawm vuam cov txiaj ntsig hauv ntau daim ntawv thov.
