Resistance chaw welding yog ib txoj kev siv dav hauv ntau yam kev lag luam rau kev koom nrog cov hlau. Kev ua tau zoo thiab kev ua tau zoo ntawm cov txheej txheem no feem ntau nyob ntawm cov khoom siv rau vuam electrodes. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov ntsiab lus tseem ceeb los txiav txim siab thaum xaiv cov khoom siv electrode rau qhov chaw vuam tshuab.
- Conductivity: Cov hluav taws xob conductivity ntawm cov khoom siv electrode yog qhov tseem ceeb rau kev tsim hluav taws xob zoo thaum lub sijhawm vuam. Copper thiab nws cov alloys, xws li tooj liab-chromium thiab tooj liab-zirconium, yog cov kev xaiv nrov vim lawv cov hluav taws xob hluav taws xob siab. Lawv tso cai rau kev hloov hluav taws xob zoo dua thiab pab kom ua tiav cov welds zoo ib yam.
- Thaum tshav kub kub Resistance: Resistance chaw welding generates ib tug tseem ceeb npaum li cas ntawm tshav kub, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm cov electrodes. Yog li, cov khoom siv electrode xaiv yuav tsum muaj cov cua kub zoo heev los tiv thaiv kev ua haujlwm ntev yam tsis muaj deformation lossis degradation. Cov hlau refractory zoo li tungsten thiab molybdenum paub txog lawv qhov tshwj xeeb kub ua haujlwm.
- Hardness: Txhawm rau kom ruaj khov thiab sib xws, cov khoom siv electrode yuav tsum muaj qhov nyuaj txaus los tiv thaiv hnav thiab deformation thaum vuam. Cov ntaub ntawv nyuaj tuaj yeem tswj tau lawv cov duab thiab muab qhov chaw vuam txhim khu kev qha rau lub sijhawm ntev. Cov ntaub ntawv zoo li tooj liab-chromium-zirconium (CuCrZr) paub txog lawv cov hardness siab thiab durability.
- Thermal conductivity: Sib nrug los ntawm hluav taws xob conductivity, thermal conductivity kuj yog ib qho tseem ceeb. Kev siv hluav taws xob zoo los ntawm qhov chaw weld yog qhov tseem ceeb los tiv thaiv overheating thiab tswj cov vuam zoo. tooj liab-raws li electrodes, vim lawv cov thermal conductivity, feem ntau nyiam vim li no.
- Vuam txheej txheem thiab cov khoom sib xws: Xav txog cov txheej txheem vuam tshwj xeeb thiab cov ntaub ntawv tau koom nrog. Cov ntawv thov sib txawv yuav xav tau cov khoom siv electrode sib txawv. Piv txwv li, thaum welding high-strength steels, electrodes nrog zoo tsis kam mus hnav thiab deformation nyob rau hauv siab siab tej zaum yuav tsim nyog.
- Kev txiav txim siab nqi: Tus nqi ntawm cov khoom siv electrode tuaj yeem sib txawv heev. Txawm hais tias cov ntaub ntawv zoo li cov tooj liab ntshiab muaj kev ua tau zoo, lawv yuav tsis raug nqi rau txhua daim ntawv thov. Kev ntsuas kev ua tau zoo nrog kev txwv nyiaj txiag yog qhov tseem ceeb.
- Kev Kho: Kev tu electrode tsis tu ncua yog qhov tseem ceeb rau lub neej ntev ntawm cov khoom siv vuam. Qee cov khoom siv electrode yuav xav tau kev saib xyuas ntau dua li lwm tus. Xav txog qhov yooj yim ntawm kev saib xyuas thaum xaiv cov khoom siv electrode.
Hauv kev xaus, kev xaiv ntawm cov khoom siv electrode plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab kev ua haujlwm ntawm qhov chaw vuam tshuab. Engineers thiab manufacturers yuav tsum ua tib zoo soj ntsuam cov kev cai tshwj xeeb ntawm lawv daim ntawv thov vuam thiab xaiv cov ntaub ntawv uas muaj qhov sib npaug ntawm conductivity, kub tsis kam, hardness, thiab nqi-zoo. Kev saib xyuas kom zoo yuav tsum tau ua los ua kom cov electrodes 'ntev ntev thiab zoo ib yam weld zoo.
