Leeg vuam tshuabUa Haujlwm Cov Ntsiab Cai
Tus ua hauj lwm ua haujlwm ntawm txoj hlua khi vuam yog raws cov qauv ntawm cov qauv ntawmKuj vuam, tab sis yog tshwj xeeb los tsim cov nruam, xau-} maj mam weld (ib leeg) ntawm ob lossis ntau dua cov ntawv hlau.
1. Cov ntsiab cai tseem ceeb: Kev Tiv Thaiv Txhuam Vuam Vuam
Ntawm nws cov tub ntxhais, leeg vuam yog qhov sib txawv ntawmKuj vuamCov. Nws ua haujlwm ntawm txoj ntsiab cai ntawmJoule Cua Kub: Thaum muaj hluav taws xob hluav taws xob loj dhau los ntawm cov khoom siv nrog hluav taws xob tsis kam, nws ua rau kub.
Cov qauv yooj yim rau cov cua sov tsim yog:H = I² * R * t
Qhov twg:
H{{0 {}}} kub tsim (joules)
I= Cov Hluav Taws Xob Hluav Taws Xob (Amperes)
R= hluav taws xob tsis kam ntawm cov workpiece (Ohms)
t=} Lub sij hawm tam sim no yog thov (vib nas this)
Tus yuam sij yog tias qhov kev tiv thaiv siab tshaj yog nyob ntawmkev sib tshuamNruab nrab ntawm ob daim ntawv hlau (vim yog nplaim tsis zoo thiab oxides), ua rau muaj kev kub ntxhov ntau tshaj plaws thiab ua molten, tsim ib weld nugget.
2. Tus yuam sij ntawm & lawv lub luag haujlwm
Ib leeg leeg welding tshuab ua ke ntau qhov tseem ceeb ntawm cov ntsiab cai no tsis tu ncua no:
- Cov log electrode (cov menyuam cov khoom):Cov no hloov cov hluav taws xob hauv nroog ntawm cov ntaub ntawv pov tseg. Lawv tau sib hloov, disc {{1} zoo li cov log tsheb loj uas clamp qhov chaw ua haujlwm thiab nqa lub vuam tam sim no. Lawv tseem thov kev zam txim thiab thauj cov workpiece los ntawm lub tshuab.
- Fais fab mov & maub los:Muab thiab meej tswj hwm lub siab {{0} epeptis hluav taws xob tam sim no. Cov Khoom Siv Niaj Hnub SivMid - zaus ncaj qha tam sim no (MFDC)Inverters rau kev tswj xyuas zoo dua thiab ua tau zoo.
- Siab Txiag:Siv ib lub zog sib xws thiab kho tau tus kheej (ntawm pneumatatics (ntawm pneumatics) rau hluav taws xob log, ua kom muaj kev sib cuag hluav taws xob zoo thiab Forging cov hlau molten.
- Cua Txias Zog:Circulates dej los ntawm cov hluav taws xob hauv av thiab cov hloov hluav taws xob kom tshem tawm cov cua kub loj loj tsim thiab tiv thaiv kev puas tsuaj.
3. Cov kauj ruam - ntawm {{2}-}} Ruam ua haujlwm ua haujlwm
Cov txheej txheem tuaj yeem pom hauv cov FlowCharchart hauv qab no, uas tau qhia ob hom kev ua haujlwm tseem ceeb:
- Nruam Seam:Lub log electrode tig ntawm qhov nrawm nroos thaum uas ntws tsis tu ncua, tsim ib qho, tsis muaj kev cuam tshuam weld. Qhov no yog qhov zoo rau kev ua kom muaj kev sib koom ua ke zoo kawg nkaus rau cov thawv, tso tsheb hlau luam, lossis kav dej.
- Dov - chaw (sib qab) seam:Lub tshuab ua haujlwm nyob rau hauv ib qho pib -} nres voj voog. Lub log tig ib qho luv luv ("suab"), nres, thiab tom qab ntawd thiab tom qab ntawd ib qho chaw tam sim no {}}}} ua ntej rov ua dua. Qhov no tsim cov kev sib tshooj ntawm Overlapping Weld Nuggets. Hom qauv no feem ntau qhov chaw nres tsheb ciav hlau tsis tsim nyog, raws li nws txo cov tswv yim cua sov thiab minimizes distortion.
4. Qhov zoo thiab txwv
| Qhov Zoo | Kev txwv |
|---|---|
| Cov nqi ntau lawm& Ceev | Cov khoom siv siab |
| Tsim tawmHermetically kawpob qij txha | Txwv rau ceg tawv ua ke thiab linear / Chaw Sib Tsuaj Crametric |
| Tsis muaj cov neeg sivzoo li muab cov pas nrig lossis roj av | Tsis yog txhua tus hlau yog qhov haum (piv txwv, siab thermal conductivity hlau yog qhov nyuaj) |
| Cov txheej txheem huv sinrog tsis muaj lub txim taws lossis cov pa taws | Kev sib tshooj sib tshooj ntxiv qhov hnyav thiab cov khoom siv piv rau pob tw pob tw |
| Kev rov ua duaThiab Automation | Yuav tsum tau cov kev paub tseem ceeb rau cov kev ntsuas kom raug kom raug |
5. Cov Ntawv Thov Tib Neeg
Leeg vuamPuas yog cov qauv kev lag luam rau ib daim ntawv thov yuav tsum tau txuas ntxiv mus ntxiv, xau-} pov thawj sib koom:
- Automotive:Roj tso tsheb hlau luam, tso lub tshuab tso pa roj, cov roj lim, cov roj lim roj, catalytic convers.
- Muaj:Cov raj mis siab, cov kheej kheej kheej kheej, cov tub sab tub yees (compressors, evapators), shipping nruas thiab tej kas moos.
- Aerospace:Roj kab thiab tso tsheb hlau loj.
- Cov neeg siv khoom lag luam:Cov khoom siv hauv tsev (piv txwv li, tshuab tso tsheb hlau taws taub hau dej, tshuab ntxhua khaub ncaws tubs).
