Spot Welding yog ib txoj hauv kev hauv kev tsim khoom, siv los koom nrog ob lossis ntau dua cov khoom siv hlau ua ke los ntawm kev yaj lawv cov npoo thiab sib xyaw ua ke.Txiv ntseej qhov chaw vuam tshuab yog ib hom tshwj xeeb ntawm qhov chaw vuam cov cuab yeej tsim los txuas cov txiv ntseej lossis lwm yam threaded fasteners rau hlau qhov chaw.Cov tshuab no siv cov khoom siv hluav taws xob tshwj xeeb, thiab kev xaiv cov khoom siv hluav taws xob yog qhov tseem ceeb hauv lawv qhov kev ua tau zoo.
Cov khoom siv ntawm cov electrodes siv nyob rau hauv cov txiv ntoo qhov chaw vuam tshuab tuaj yeem cuam tshuam rau qhov zoo thiab kav ntev ntawm cov welds.Feem ntau, electrodes rau cov txiv ntoo qhov vuam yog tsim los ntawm cov ntaub ntawv uas muab hluav taws xob zoo, ua haujlwm kub, thiab kav ntev.Cia peb saib ze dua ntawm qee cov khoom siv electrode siv hauv cov txiv ntoo qhov chaw vuam tshuab:
- Tooj Alloys: Copper thiab nws cov alloys, xws li tooj liab-chromium thiab tooj liab-zirconium, yog dav siv rau cov ntaub ntawv electrode.Copper muaj cov khoom siv hluav taws xob zoo heev thiab ua haujlwm kub, ua rau nws haum rau qhov kub thiab txias tsim thaum lub sijhawm vuam.Copper electrodes kuj pom zoo rau hnav, uas yog ib qho tseem ceeb rau lub neej ntev ntawm cov khoom.
- Tooj liab tungsten alloys: Copper tungsten yog cov khoom siv sib xyaw ua ke uas sib txuas cov hluav taws xob conductivity ntawm tooj liab nrog cov cua sov ua haujlwm thiab ua haujlwm ntev ntawm tungsten.Nws yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj kev sib koom ua ke tam sim no thiab rov ua dua welding cycles.Tooj tungsten electrodes tuaj yeem tiv taus kev siv ntev yam tsis muaj teeb meem loj.
- Molybdenum: Molybdenum electrodes paub txog lawv qhov kub thiab txias thiab muaj peev xwm tswj tau lawv cov duab nyob rau hauv huab cua kub.Txawm hais tias lawv yuav tsis muaj hluav taws xob zoo li tooj liab, lawv tseem tsim nyog rau qee qhov chaw siv vuam, tshwj xeeb tshaj yog cov khoom siv sib txawv lossis qhov chaw kub heev.
- Chav Kawm 2 tooj liab: Chav Kawm 2 tooj liab electrodes yog qhov kev xaiv zoo rau cov txiv ntoo qhov chaw vuam tshuab.Txawm hais tias lawv tsis muaj tib theem ntawm cov cua sov ua haujlwm zoo li tooj liab alloys lossis tooj liab tungsten, lawv tseem muaj peev xwm muab cov welds zoo hauv ntau daim ntawv thov.
Xaiv cov khoom siv hluav taws xob zoo rau cov txiv ntoo qhov chaw vuam tshuab yog nyob ntawm ntau yam, nrog rau cov khoom siv welded, qhov yuav tsum tau ua kom zoo ntawm cov welds, thiab qhov xav tau ntim ntau lawm.Copper alloys thiab tooj liab tungsten feem ntau yog cov kev xaiv saum toj kawg nkaus vim lawv cov yam ntxwv ua tau zoo, tab sis kev xaiv yuav txawv raws li cov kev xav tau tshwj xeeb.
Hauv kev xaus, cov khoom siv ntawm cov electrodes siv nyob rau hauv cov txiv ntoo qhov chaw vuam tshuab yog ib qho tseem ceeb hauv kev ua tau zoo thiab ruaj khov welds.Kev xaiv ntawm cov khoom yog nyob ntawm yam xws li hluav taws xob conductivity, tshav kub tsis kam, thiab hnav tsis kam.Cov neeg tsim khoom yuav tsum ua tib zoo xav txog lawv cov kev xav tau tshwj xeeb los xaiv cov khoom siv electrode uas haum tshaj plaws rau lawv cov txiv ntoo qhov chaw vuam tshuab.
