Q1: Dab tsi tshwm sim yuav tsum muaj ua ntej vuam?
Ua ntej vuam, cov yeeb nkab xaus yuav tsum yog beveled (xws li v {{0} {{1} {1} {1} {1} {1}- zoo fusion. Qhov saum npoo yuav tsum tau ntxuav kom tshem roj, xeb, thiab zeb nplai, feem ntau los ntawm kev sib tsoo lossis tshuaj ntxuav kom huv. Rau tuab {{{}}} phab ntsa} palled yeeb nkab, preheating (100 {}}} xyoo 200 degree) yuav tsim nyog los tiv thaiv kev tawg txias. Vuam consumables (Electrodes lossis xaim) yuav tsum phim cov yeeb nkab tshuaj ntawm cov yeeb nkab steel, xws li e7018 electrodes lossis ER70s-6 xaim. Tsis tas li ntawd, kev thaj chaw vuam yuav tsum qhuav kom tsis txhob muaj cov dej noo-tauv porosity.
Q2: Yuav ua li cas vuam lug thiab cov ntaub ntawv pom zoo?
Cov kev vuam hlau ib txwm muaj cov qauv hlau arc vuam (Submer), cov pa roj hmab arc vuam (gtsten inert roj vuam (gtaw / tig). Blaw thiab Gmaw yooj yim rau on -}} site} thaj chaw teeb tsa, thaum pom yog tsim nyog rau loj {2} kev lag luam loj heev. Hais txog vuam centerables, qis-} i {{{}} i {}} i {}} hydrogen electrodes (xws li E7018) muab lub zog zoo thiab tawv. Vuam qhov tsis yuav tsum tau hloov kho raws li lub phab ntsa tuab kom tsis txhob muaj kev kub ntxhov thiab tsis muaj kev sib luag. Tshaj tawm - Weld pom kev thiab kev kuaj tsis yog kev puas tsuaj.
Q3: Yuav ua li cas tuaj yeem siv vuam tsis zoo?
Cov tsis xws luag muaj cov porosity, tsis muaj fusion, thiab cov kab nrib pleb, uas tuaj yeem raug txo los ntawm kev kho cov vuam txheej txheem. Porosity feem ntau tshwm sim los ntawm cov hluav taws xob ntub lossis cov ntaub thaiv tsis txaus, yog li cov ntaub ntawv vuam yuav tsum khaws cia kom qhuav. SLAG cov kev suav tuaj yeem zam tau los ntawm kev nce qhov tam sim no thiab tu sawb ntawm kev hla. Tsis muaj fusion tuaj yeem raug daws los ntawm kev kho lub vuam kaum thiab nrawm. Kev tawg txias tuaj yeem tiv thaiv los ntawm preheating thiab post {{}} cua sov ua raws los ntawm kev ua kom qeeb. Tshaj tawm - Weld pom kev, thiab x {- pay lossis ultrasonic kuaj yuav tsum tau ua yog tias tsim nyog.
Q4: Yuav ua li cas txias thiab kub ua haujlwm cuam tshuam rau cov khoom?
Txias ua haujlwm (xws li cov duab txias txias) tuaj yeem txhim kho qhov raug thiab saum npoo ntawm cov kav dej steel, tab sis nws tuaj yeem txo kev ntxhov siab thiab nce ntxiv kev ntxhov siab. Kub ua hauj lwm (xws li kub dov) txhim kho cov khoom siv cov khoom siv tau tab sis yuav ua rau cov nplai thiab qhov sib txawv thiab qhov sib txawv. Txias -} Cov hauj lwm steel kav feem ntau yuav tsum tau txais kev kho kom ceev nrawm, thaum kub}} ua haujlwm yuav xav tau ua kom zoo dua rau cov mov zom kom zoo. Cov neeg siv yuav tsum xaiv txoj kev ua tiav raws li qhov kawg siv. Piv txwv, cov kab mob txias yog qhov haum rau cov khoom siv tshuab hluav taws xob, thaum kub dov yog feem ntau siv rau cov txheej txheem kav dej.
Q5: Yuav ua li cas tshaj tawm - weld kev kho cua sov ua tau?
Tshaj tawm - Weld Kev Kho Mob Kub (PWT) feem ntau siv los daws cov kev ntxhov siab weld seem thiab txhim kho kev nyuaj siab. Ib cov txheej txheem cuam tshuam nrog 600 - 6 teev℃rau 1 teev rau ib nti ntawm thickness, ua raws los ntawm qeeb cua txias. PWHT yog qhov tsim nyog rau cov kav dej tuab cov kav dej uas tuab los yog cov ntaub ntawv khi tau txwv los tiv thaiv kev tawg qeeb. Yuav tsum tau kuaj nyuaj tom qab kev kho cua sov kom ntseeg tau tias lub hardness tsis tshaj cov qauv kev txwv (feem ntau qis dua 200 HB). Yog tias tag nrho cov kev kho cua sov tsis tau, cua kub hauv ib cheeb tsam lossis kev sib cav tuaj yeem siv ua lwm yam.
