Kev saib xyuas ntawm cov yeeb nkab txias rub welded yuav tsum tau saib xyuas raws li cov qauv kev saib xyuas zoo. Txawm hais tias qhov kev ua haujlwm zoo, nws yog ib qho tsim nyog yuav tsum tau ua txhua yam kev saib xyuas ntawm lub welded yeeb nkab chav tsev kom tsis txhob muaj kev ua haujlwm tsis zoo thiab ua kom cov khoom zoo.

Nyob rau hauv tus txheej txheem ntawm kev tuav cia txias welded kav, qhov chaw uas pom tias yuav hnav hnyav yuav tsum tau hloov sai li sai tau. Kev saib xyuas tsis tu ncua thiab kev tiv thaiv cov tshuab los ntawm cov neeg ua haujlwm tiv thaiv kev tshaj lij, xws li ntxiv cov roj lubricating, thiab lwm yam. Tom qab ntawd siv cov roj zoo los tiv thaiv xeb ntawm cov zawv zawg sab los tiv thaiv cov cuab yeej los ntawm oxidizing thiab xeb, tshwj xeeb tshaj yog thaum nws tsis ua haujlwm ntev. . Ua ib txoj haujlwm zoo hauv kev saib xyuas cov ntsiab lus yog qhov zoo heev rau kev ua haujlwm ntawm cov kav dej txias txias, thiab nws tuaj yeem ua kom muaj kev vam meej ntawm kev tsim khoom.

Hauv kev tu txhua hnub, lub ntsiab lus tseem ceeb yog yuav tsum tau ceev faj, txawm hais tias nws yog hais txog kev ua haujlwm tag nrho ntawm cov yeeb nkab txias welded, lossis txog kev hloov ntawm ntau qhov chaw, tsis tu ncua xyuas qhov hnav thiab tsim kua muag ntawm qhov chaw, tshwj xeeb tshaj yog thaum ua haujlwm. yog hnyav, them nyiaj ntau dua rau cov khoom no, yog tias hnav hnyav cuam tshuam rau cov txheej txheem ntau lawm.

1. Nyob rau hauv cov nqe lus ntawm kev khwv nyiaj txiag, lub suab nrov ntawm txias-draw welded yeeb nkab yog me me; kev siv cov dej txias txias yog ib puag ncig tus phooj ywg thiab txuag hluav taws xob.
2. Nyob rau hauv cov nqe lus ntawm kev siv, welded kav yog siv ntau thiab ntau dav thiab haum rau kev ua liaj ua teb thiab industrial ntau lawm.
3. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, welded yeeb nkab khoom ntawm txias-draw welded kav yog zoo, cov welds yog zoo, tsis muaj ntau burrs, ceev ceev, lub zog txuag thiab txuag nqi.
4. Vim hais tias cov yeeb nkab welded high-frequency welded yeeb nkab muaj qhov zoo ntawm cov vuam zoo, me me sab hauv thiab sab nraud burrs, vuam ceev ceev, thiab tsis tshua muaj zog noj, nws tau siv dav thiab txhawb nqa.
5. Ntawm chav tsev welded yeeb nkab, feem ntau yog ua tau los tsim cov kav dej heterosexual, thiab ntau cov kav dej square thiab square yog tsim. Vim tias cov kav dej square thiab cov duab plaub muaj qhov loj me me, cov kav dej txias txias tuaj yeem tiv taus ntau dua dabtsi yog khoov quab yuam, uas tuaj yeem txuag tau ntau cov hlau, Nws muaj qhov zoo ntawm kev txuag lub sijhawm ua haujlwm thiab txo qhov hnyav ntawm cov khoom, yog li nws tau nrov zuj zus. thiab siv ntau yam ntawm kev lag luam thiab kev ua liaj ua teb.

Muaj ntau cov txheej txheem hauv cov txheej txheem ntawm welded yeeb nkab ua, thiab txhua yam xav tau peb cov xim. Cov kav dej welded yuav tsum tau ua ntau yam txheej txheem ua ntej siv. Kev kho cua sov ntawm welded steel yeeb nkab yog qhov txuas tseem ceeb hauv cov txheej txheem ntawm welded steel yeeb nkab. Thermal processing yog cov txheej txheem thermal ua hlau uas ua kom sov, ua kom sov, thiab txias cov ntaub ntawv hlau hauv ib qho nruab nrab, thiab tswj cov khoom ntawm cov hlau los ntawm kev hloov cov qauv metallographic ntawm qhov chaw lossis sab hauv ntawm cov khoom.

Thaum lub sij hawm cua sov thiab cua txias txheej txheem ntawm cov txheej txheem welded yeeb nkab workpiece, vim lub inconsistent cua txias ceev thiab lub sij hawm ntawm lub nto txheej thiab cov tub ntxhais txheej, ib tug kub sib txawv yuav tsim, uas ua rau uneven ntim expansion thiab contraction, thiab kev nyuaj siab, uas yog. , thermal stress. Nyob rau hauv qhov kev txiav txim ntawm thermal stress, thawj qhov kub ntawm cov txheej saum npoo yog qis dua li ntawm cov tub ntxhais txheej, thiab lub shrinkage yog ntau dua li ntawm cov tub ntxhais txheej, kom cov tub ntxhais txheej yog stretched. Thaum cov cua txias tiav lawm, daim tawv nqaij yog compressed thiab cov tub ntxhais yog stretched, vim hais tias qhov txias ntim ntawm cov tub ntxhais yuav tsis tuaj yeem mus dawb.
