Resistance chaw welding yog txheej txheem siv dav hauv kev tsim khoom rau kev koom nrog cov khoom siv hlau. Txawm li cas los xij, ib qho teeb meem uas cov neeg ua haujlwm feem ntau ntsib yog electrode hnav. Electrode hnav tuaj yeem cuam tshuam qhov zoo ntawm welds thiab kev ua haujlwm ntawm cov txheej txheem vuam. Hauv tsab xov xwm no, peb yuav tshawb txog cov yam tseem ceeb uas ua rau cov khoom siv electrode nyob rau hauv qhov chaw vuam tshuab.
- Khoom Hardness: Lub hardness ntawm cov khoom siv electrode plays lub luag haujlwm tseem ceeb hauv nws qhov hnav tsis kam. Cov ntaub ntawv softer yuav hnav tawm sai dua li cov tawv tawv. Cov neeg tsim khoom feem ntau siv tooj liab alloys rau electrodes vim lawv cov khoom siv hluav taws xob zoo thiab muaj zog nruab nrab. Txawm li cas los xij, txawm tias nyob rau hauv cov ntaub ntawv no, kev hloov pauv hauv hardness tuaj yeem cuam tshuam rau tus nqi hnav.
- Vuam tam sim no: Cov vuam tam sim no siv thaum lub sijhawm ua haujlwm ncaj qha cuam tshuam electrode hnav. Cov vuam tam sim no siab dua ua kom muaj cua sov ntau dua ntawm cov lus qhia electrode, ua rau lawv hnav sai dua. Nrhiav qhov zoo sib npaug ntawm lub neej tam sim no thiab electrode yog qhov tseem ceeb rau kev ua kom zoo dua qub.
- Lub sijhawm vuam: Lub sij hawm vuam ntev tuaj yeem ua kom cov electrode hnav. Lub sijhawm vuam ntev ntev ua rau muaj kev cuam tshuam ntev rau cov cua sov thiab siab, uas tuaj yeem ua rau cov khoom siv electrode. Kev ua kom txias txaus thiab cov tswv yim sib hloov electrode tuaj yeem pab txo qis hnav hauv cov xwm txheej no.
- Electrode Force: Lub zog siv rau cov electrodes cuam tshuam rau ob qho tib si zoo ntawm vuam thiab electrode hnav. Kev quab yuam ntau dhau tuaj yeem ua rau electrode deformation thiab nce hnav. Ntawm qhov tod tes, kev quab yuam tsis txaus tuaj yeem ua rau tsis zoo weld. Kev tuav lub zog electrode kom raug yog qhov tseem ceeb hauv kev txo qis hnav.
- Electrode Contamination: Cov kab mob ntawm cov khoom ua haujlwm, xws li xeb, xim, lossis roj, tuaj yeem ua kom cov electrode hnav. Cov tshuaj no tuaj yeem ua raws li cov khoom siv electrode thiab degrade nws cov kev ua tau zoo. Kev npaj ua haujlwm kom zoo thiab kev tu electrode tsis tu ncua yog qhov tseem ceeb tiv thaiv kev ntsuas.
- Electrode Tsim: Kev tsim cov electrodes, nrog rau lawv cov duab thiab qhov loj, tuaj yeem cuam tshuam rau hnav. Cov khoom siv hluav taws xob tsim tau zoo faib tam sim no sib npaug, txo cov cua sov hauv zos thiab hnav. Cov khoom siv hluav taws xob kuj tuaj yeem kho lossis coated los txhim kho lawv cov hnav tsis kam.
- Txias Systems: Kev ua kom txias tsis txaus tuaj yeem ua rau cov hluav taws xob ntau dhau, ua rau hnav nrawm dua. Cov tshuab ua kom txias zoo, xws li dej los yog cua txias, yog qhov tseem ceeb rau kev tswj cov electrode qhov kub thiab txias hauv qhov kev siv tau.
- Khoom siv ua haujlwm: Cov khoom siv welded kuj cuam tshuam electrode hnav. Cov ntaub ntawv nyuaj thiab ntau dua abrasive feem ntau yuav ua rau cov electrode hnav sai dua piv rau cov ntaub ntawv softer.
- Tus neeg ua haujlwm txawj thiab kev cob qhia: Kev txawj ntse ntawm tus neeg teb xov tooj plays lub luag haujlwm tseem ceeb hauv electrode hnav. Kev cob qhia kom raug thiab kev txhim kho kev txawj ntse tuaj yeem pab cov neeg ua haujlwm txiav txim siab txog kev siv vuam thiab cov txheej txheem kom txo qis hnav.
Hauv kev xaus, electrode hnav hauv qhov chaw vuam tshuab yog cuam tshuam los ntawm ntau yam. Kev nkag siab txog cov xwm txheej no thiab lawv cov kev sib cuam tshuam yog qhov tseem ceeb rau kev txhim kho cov txheej txheem vuam, txo qis qis, thiab ua tiav cov vuam zoo. Los ntawm kev ua tib zoo tswj cov khoom xaiv, vuam tsis, thiab kev saib xyuas, cov neeg tsim khoom tuaj yeem txuas lub neej ntawm electrodes thiab txhim kho tag nrho cov txiaj ntsig ntawm lawv cov haujlwm vuam.
