Ua kom tiav thiab Ua Ntej Ua Ntej Ua Ntej Ua Ntej
Teeb meem tshwm sim thaum vuam ib tug kaw qauv los yog cov qauv uas muaj qhov chaw txwv kom cov neeg soj ntsuam tsis pom qhov vuam zoo tom qab lub phaj los yog ib feem ntawm lub kaw qauv. Qhov tseeb no yuav tsum tau ua tib zoo xav txog hauv kev tsim thiab tsim cov txheej txheem txheej txheem.
Ua raws li qhov kev pom no, dab tsi yog qhov underfill hauv vuam?
Ua tsis tiav - Ib tug mob nyob rau hauv uas lub weld lub ntsej muag los yog cov hauv paus hniav nthuav dav hauv qab ntawm qhov chaw nyob ib sab ntawm lub hauv paus hlau.
Ib yam nkaus, dab tsi ua rau kub hnyiab hauv vuam? Ua rau : Cov cua sov ntau dhau yog thawj qhov ua rau ntawm hlawv dhau . Muaj loj heev ntawm lub hauv paus qhib ntawm lub weld kev sib koom tes tseem tuaj yeem ua rau hlawv dhau . Kev nce mus ncig ceev pab, ib yam nkaus, tshwj xeeb tshaj yog thaum vuam ntawm aluminium, uas yog nquag ua kom sov.
Nyob rau hauv no hais txog, dab tsi yog vim li cas welding defects?
Qhov laj thawj tseem ceeb
- Hydrogen embrittlement.
- Cov kev nyuaj siab seem.
- Kev tawg.
- Distortion.
- Gas suav nrog.
- suav nrog.
- Tsis muaj fusion thiab nkag tsis tiav.
- Lamellar kua muag.
Koj yuav ua li cas tiv thaiv vuam tsis xws luag?
Kev kho mob:
- Preheat cov hlau raws li xav tau.
- Muab kom txias ntawm thaj chaw txuas.
- Siv kev tsim ua ke kom tsim nyog.
- Tshem tawm cov khoom tsis huv.
- Siv hlau tsim nyog.
- Nco ntsoov weld ib cheeb tsam txaus.
- Siv vuam ceev thiab amperage tam sim no.
- Txhawm rau tiv thaiv cov kab nrib pleb kom paub tseeb tias lub qhov crater tau ntim kom zoo.

Dab tsi yog ob lub zog nyob rau hauv automatic yuav pib nyob rau hauv?
Qee qhov kev xa tawm tsis siv neeg yuav hloov tawm ntawm 1st thaum koj mus txog qee qhov nrawm, xws li 30 mph, txhawm rau tiv thaiv kev puas tsuaj rau kev xa lossis lub cav, lossis txiav lub zog rau lub cav. Thiab nrog lwm tus, yog tias koj xaiv 2, kev kis tau pib hauv lub iav thib 2 thiab raug kaw hauv lub iav ntawd
Kev tswj nqes hav hauv vuam yog dab tsi?
Inductance tswj txoj kab nqes hav. Feem ntau transformer welders muaj ib txoj kab nqes. Cov nqes hav txuas ruaj ruaj sib txawv ntawm cov chaw tsim khoom mus rau cov chaw tsim khoom nyob rau hauv ntau npaum li cas txoj kab nqes tau muab tso rau hauv lub tshuab. Kev tswj txoj kab nqes cia koj txwv qhov luv luv-circuit tam sim no
Dab tsi yog vuam roj vuam siv rau?
Oxy-fuel welding (feem ntau hu ua oxyacetylene vuam, oxyacetylene vuam, lossis roj vuam hauv Teb Chaws Asmeskas) thiab oxy-fuel txiav yog cov txheej txheem uas siv roj gases (los yog kua roj xws li roj av) thiab oxygen rau vuam lossis txiav hlau
Dab tsi yog qhov txawv ntawm AC thiab DC vuam vuam?
DC polarity yog siv nyob rau hauv feem ntau vuam daim ntaub ntawv. Nws ua kom cov khoom siv txuas tau zoo dua piv rau AC. Nws tsim ib qho chaw ruaj khov dua, vuam yooj yim dua thiab tsis tshua muaj tawg. Koj tuaj yeem siv DC tsis zoo rau kev tso nyiaj sai dua thaum vuam nyias daim hlau lossis siv DC zoo rau kev nkag mus rau hauv cov hlau ntau dua
Dab tsi ntawm electrode yog siv nyob rau hauv submerged arc vuam?
Electrodes muaj rau weld me me steels, siab carbon steels, tsawg thiab tshwj xeeb alloy steels, stainless hlau thiab ib co ntawm cov nonferrous tooj liab thiab npib tsib xee. Electrodes feem ntau yog tooj liab coated los tiv thaiv xeb thiab ua kom lawv cov hluav taws xob conductivity
