Resistance chaw vuam tshuab yog cov cuab yeej tseem ceeb hauv ntau qhov kev lag luam, siv los koom nrog cov hlau ua ke los ntawm kev siv cov cua sov thiab siab. Cov tshuab no tuaj yeem siv tau ntau txoj hauv kev, txhua tus nrog nws qhov zoo thiab kev txwv. Nyob rau hauv tsab xov xwm no, peb yuav tshawb xyuas cov kev sib txawv ntawm cov khoom siv hluav taws xob rau cov khoom siv vuam tshuab.
- Direct Current (DC) Fais fab mov:
- Nqe lus piav qhia:DC fais fab mov yog txoj kev siv ntau tshaj plaws rau kev tiv thaiv qhov chaw vuam. Nws muab qhov ntws tsis tu ncua ntawm cov hluav taws xob tam sim no hauv ib qho kev taw qhia, ua kom ruaj khov thiab tswj kev vuam.
- Qhov zoo:Kev tswj xyuas meej ntawm cov txheej txheem vuam, zoo heev rau cov ntaub ntawv nyias, thiab dav muaj.
- Kev txwv:Tsis haum rau vuam cov ntaub ntawv nrog txawv thicknesses, yuav ua rau electrode hnav, thiab tej zaum yuav xav tau tshwj xeeb hwj chim qhov chaw.
- Alternating Current (AC) Fais fab mov:
- Nqe lus piav qhia:AC fais fab mov ib ntus thim rov qab cov kev taw qhia ntawm cov hluav taws xob tam sim no, tsim kom muaj qhov sib npaug sib npaug nrog cov khoom siv hluav taws xob tsawg dua.
- Qhov zoo:Haum rau ntau yam ntaub ntawv thiab thicknesses, txo qhov kev pheej hmoo ntawm overheating, thiab muab ib tug huv weld.
- Kev txwv:Tej zaum yuav xav tau kev saib xyuas ntau dua vim muaj kev hnav ntau dua ntawm vuam transformers.
- Inverter-based fais fab mov:
- Nqe lus piav qhia:Inverter thev naus laus zis hloov AC lub zog nkag mus rau hauv DC lub zog thiab tom qab ntawd rov qab mus rau AC zog siab. Txoj kev no muaj kev tswj xyuas ntau dua thiab hloov tau yooj yim hauv vuam.
- Qhov zoo:Ntau yam ntau yam, yoog tau rau cov khoom sib txawv, thiab muab kev tswj xyuas meej ntawm cov khoom siv vuam.
- Kev txwv:Tus nqi pib pib tuaj yeem siab dua, thiab kev saib xyuas yuav xav tau kev paub tshwj xeeb.
- Capacitor Discharge (CD) Vuam:
- Nqe lus piav qhia:CD welding siv cov capacitors los khaws cov hluav taws xob hluav taws xob, tso tawm hauv qhov luv luv, lub zog tawg. Txoj kev no feem ntau yog siv rau cov khoom siv me me los yog cov vuam me me.
- Qhov zoo:Kev tsim hluav taws xob tsawg, tsim nyog rau cov ntaub ntawv nyias, thiab txo qhov kev pheej hmoo ntawm deformation.
- Kev txwv:Txwv rau cov ntawv thov tshwj xeeb vim nws cov zis hluav taws xob qis dua.
- Pulsed tam sim no vuam:
- Nqe lus piav qhia:Pulsed tam sim no vuam alternates ntawm qib siab thiab qis tam sim no thaum lub vuam txheej txheem. Nws yog tshwj xeeb tshaj yog pab tau rau vuam dissimilar hlau los yog ilv cov ntaub ntawv.
- Qhov zoo:Txo cov cua kub nkag, txo qis distortion, thiab txhim kho kev tswj ntawm cov hlaws vuam.
- Kev txwv:Yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev txawj ntse.
Hauv kev xaus, qhov kev xaiv ntawm cov khoom siv hluav taws xob rau qhov chaw vuam tshuab yog nyob ntawm ntau yam, nrog rau cov khoom siv welded, qhov xav tau weld zoo, thiab cov peev txheej muaj. Txhua txoj kev muaj nws qhov tshwj xeeb zoo thiab cov kev txwv, thiab xaiv txoj cai yog qhov tseem ceeb rau kev ua tiav cov welds zoo ib yam thiab txhim khu kev qha hauv ntau daim ntawv thov kev lag luam.
