Ib txoj kev welded hlau yog hais txog cov qauv hlau lossis cov khoom siv uas tau tsim los ntawm kev koom nrog ob lossis ntau cov hlau los ntawm cov txheej txheem vuam. Nws tsis yog ib qho ntawm cov hlau hauv nws lub xeev qub tab sis ib qho chaw sib koom ua ke tsim los ntawm kev sib txawv ntawm cov hlau sib cais uas khi lawv ua ke. Qhov laj thawj no tau tiav los ntawm kev tswj hwm cua sov tswj, uas melts cov chaw ntawm cov hlau) ntawm kev sib koom tes hlau) ntawm kev sib koom ua ke nrog rau daim ntawv sib koom ua ke metallurgical. Raws li qhov tshwm sim, lub zog welded hlau ua ib qho, koom ua ke ntau dua li kev sau cov khoom sib cais sib xyaw ua ke los ntawm sab nraud rog.
Kev tsim ntawm welded hlau tso siab rau cov ntsiab cai ntawm kev sib koom ua metallurgical. Thaum cov hlau yog rhuab rau lawv cov lus melting thaum lub sij hawm vuam, cov atoms nyob rau ntawm ib daim uas tau txais lub zog txaus kom tawg ntawm lawv cov haujlwm qub. Raws li lub molten hlau txias, cov eds intermix thiab ua cov ntawv sib txuam tshiab hla kev sib koom ua ke, tshem tawm tus ciam ntawm cov hlau thawj. Cov txheej txheem no yog txawv ntawm cov txheej txheem sib koom ua ke, xws li bolting lossis clamping, uas cov hlau nyob nyias thiab muaj tuav ua ke los ntawm kev sib txhuam lossis siab. Nyob rau hauv ib tug welded hlau, sib koom ua ke ua ntau ib feem ntawm tus qauv hlau, nrog cov khoom siv weld (cov khoom siv ntxiv) sib koom ua ke nrog cov chaw ib puag ncig.
Lub welded hlau cov khoom pov thawj tshwj xeeb uas tau muab nws cais tawm ntawm tsis yog - Welded hlau lossis cov koom nrog lwm txoj kev. Ib qho ntawm nws cov yuam sij yog cov qauv kev ntseeg. Ib qho kev siv hlau kom zoo tuaj yeem faib cov kev ntxhov siab ncaj ncees nyob thoob plaws ntawm tag nrho cov qauv, tsis yog muaj feem xyuam ntawm cov ntsiab lus sib txuas (raws li muaj ntau nrog bolts lossis rivetts). Qhov no ua rau nws tiv taus cov khoom tsis ua haujlwm, txawm tias nyob hauv cov nra hnyav lossis kev ntxhov siab dua. Piv txwv li, welded steel ci hauv ib lub tsev tuaj yeem ris qhov hnyav ntawm tus qauv uas tsis muaj kev pheej hmoo ntawm lub sijhawm, ua kom ntev} lub sij hawm ruaj khov.
Lwm txhais tau cov lus qhia yog customizability. Welded Cov hlau tuaj yeem ua kom zoo li cas rau hauv cov ntaub ntawv nyuaj uas yuav nyuaj lossis ua tiav nrog ib daim hlau. Los ntawm kev koom nrog me me, cov chaw ua lag luam tswj tau tuaj yeem tsim cov kab ke loj lossis sib npaug ntawm lub nkoj, lub cev ntawm lub tsheb, lossis lub hauv paus ntawm kev lag luam Machinery. Qhov kev hloov pauv no tso cai rau kev hloov kho dua rau cov qauv tsim tshwj xeeb rau cov qauv tsim qauv, txawm tias loj, lossis lub zog.
Cov khoom ntawm ib qho welded hlau kuj muaj feem ntau los ntawm hom kev siv hlau, thiab cov ntawv vuam siv, thiab cov ntawv tso hlau siv, thiab cov ntawv tshaj tawm} Weld kev kho mob. Piv txwv li, thaum vuam carbon hlau, siv tus muab tub lim hlau nrog lub cev muaj zog zoo sib xws rau thaj chaw welded matches lub hauv paus hlau lub zog thiab ductility. Nyob rau hauv kev sib piv, yuav tsum tau cov nyiaj uas suav rau nws qhov kev tiv thaiv qis thiab nyiam ua cov roj av tiv thaiv kom tsis txhob muaj paug. Tshaj tawm - Weld kev kho cua sov, xws li annealing kev nyuaj siab hauv Welded hlau, txhim kho nws txoj kev pheej hmoo thiab txo qhov kev pheej hmoo ntawm kev tawg.
Welded Steel yog ubiquitous nyob rau hauv kev suav tsis taus, ua ib lub luag hauj lwm tseem ceeb hauv kev tsim kho tshiab niaj hnub no. Hauv kev tsim kho, lawv tsim tus pob txha caj pas, skyscrapers, thiab chaw ua haujlwm {}}}}}}}}}}} Cov rog ib puag ncig zoo li cua, thiab cov kev npau suav. Hauv kev tsim kho tsheb thiab aerospace tsim, cov hlau welded siv nyob rau hauv chassis, lub cav sib xyaw, thiab lub teeb uas tseem tsis tau muaj cov ntaub ntawv muaj zog. Txawm nyob rau hauv cov khoom txhua hnub, xws li cov khoom siv hlau, khoom siv hauv tsev, thiab cov kav hlau hluav taws xob muab cov khoom siv uas xav tau rau cov kev ua tau zoo.
Nws yog ib qho tseem ceeb kom nco ntsoov tias tsis yog txhua cov hlau welded yog qhov zoo tib yam. Lub zog thiab kev ntseeg tau ntawm ib qho welded hlau nyob ntawm qhov zoo ntawm weld nws tus kheej. Ib qho zoo {{2} maj - tsis xws luag, thiab cov kab nrib pleb tsawg kawg nkaus, thiab haum rau nws lub hom phiaj npaj. Hloov siab, ua haujlwm weld tsis zoo tuaj yeem tsim cov ntsiab lus tsis muaj zog uas cuam tshuam rau tag nrho cov qauv, ua kom tswj tau zoo thaum lub sijhawm vuam tseem ceeb.
Hauv cov ntsiab lus, ib qho welded hlau yog ib tus qauv hlau sib xyaw ua ke los ntawm kev koom nrog cov hlau sib cais los ntawm vuam hlau, United los ntawm kev sib tw metallurgical. Nws ua ke cov khoom ntawm cov qub hlau nrog lub zog ntawm kev siv Weld, muab kev ntseeg siab, kev hloov kho kom haum rau ntau cov ntawv thov. Los ntawm loj- teev cov phiaj xwm rau cov khoom siv txhua hnub, thiab cov khoom siv hlau ua kom muaj zog, thiab cov khoom siv hlau, ua rau lawv ua haujlwm ntawm kev tsim khoom niaj hnub thiab kev tsim khoom tshiab.
