Yuav ua li cas kuv thiaj paub tias welding hlau siv?

Xaiv txoj cai vuam hlau yog lub hauv paus theem hauv kev ua tiav siab - zoo, ruaj ruaj Welds. Cov hlau tsis ncaj ncees lawm tuaj yeem ua rau cov pob qij txha tsis muaj zog, tsis xws luag lossis tawg, thiab txawm tias cov qauv ua tsis tiav hauv cov ntawv thov tseem ceeb. Nrog rau ntau hom vuam hlau muaj {}}}} txhua yam tsim rau cov ntaub ntawv tshwj xeeb, thiab ib cheeb tsam {{4 4 4} Taug kev cov kev xaiv tuaj yeem zoo li muaj kev cuam tshuam. Txawm li cas los xij, los ntawm kev tsom mus rau cov ntsiab lus tseem ceeb xws li lub hauv paus hlau, cov txheej txheem vuam, koj tuaj yeem txiav txim siab cov hlau zoo tshaj plaws rau koj qhov project.
Phim lub hauv paus hlau
Thawj thiab tseem ceeb tshaj plaws yog kom phim lub vuam hlau rau lub hauv paus hlau koj vuam. Vuam hlau yuav tsum tau qhia cov khoom sib xws me me nrog cov hlau hauv paus kom ntseeg tau tias kev siv fusion, lub zog, thiab sib xyaw, thiab sib xyaw.
Rau cov pa roj carbon) Cov xaim xaim no yog tsim kom phim lub tensile lub zog thiab ductility ntawm cov roj carbon hlau, tsim cov khoom lag luam welds uas sib xyaw ua ke nrog lub hauv paus hlau. Nws yog tus nqi-ua tau zoo thiab dav siv ntawm fab thaiv kev, kev tsim kho, thiab kho ua haujlwm.
Stainless hlau yuav tsum tau tsim cov hlau tshwj xeeb los tswj hwm nws cov khoom lag luam tsis kam thiab cov khoom siv tshuab. Piv txwv li, 308L xaim yog qhov zoo rau vuam 304 stainless hlau yog siv rau 316 stainless hlau yog siv rau cov tshuaj thiab dej qab ntsev). Cov hlau no muaj cov chromium thiab npib tsib xee nyob rau hauv daim iav ntawm lub hauv paus hlau, kom pom kev weld khaws cov anti {{6} REX} REW muaj peev xwm.
Aluminium vuam xav tau Aluminium - Cov xov hlau zoo li qub, xws li 4043 lossis} Cov hlau no tau tsim los tswj cov txhuas lub qis qis melting point thiab zam cov teeb meem xws li cov teeb meem oxide, uas tuaj yeem ua kom muaj welds tsis muaj zog.
Lwm cov hlau, zoo li Nickel alloys lossis siab- muaj zog tsawg {}} alloy, yuav tsum tau cov xov hlau tshwj xeeb. Rau HSLA cov hlau, xaim zoo li er80s {4} d2 yog siv rau vuam nickel}}}}}}}}}} {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}-
Xav txog cov txheej txheem vuam
Cov txheej txheem vuam sib txawv muaj cov kev xav tau cov hlau xaim, raws li cov xaim feem ntau ua ob qho tib si muab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob (lossis ib qho kev sib xyaw ntawm arc system).
MIG (hlau inert roj) vuam cia siab rau cov xov hlau txuas ntxiv uas tau pub dhau los ntawm kev siv phom. Cov xaim yuav tsum sib haum nrog cov roj thaiv hluav taws xob siv- Tus neeg siv hlau ua ke nrog Argon}}} helium helium blends. Mig cov xov hlau muaj nyob rau hauv ntau qhov diameters (los ntawm 0.023 "rau 0.023" rau 0.025 "lossis loj dua), nrog me dua cov ntaub ntawv rau cov hlau thicker.
Flux - Cored Arc Vuam (FCAW) siv tubuam (FCAWinates qhov kev xav tau ntawm Flux) Cov hlau no yog qhov zoo tshaj plaws rau sab nraum zoov lossis cua yam xwm txheej uas tiv thaiv roj yuav cuam tshuam. Piv txwv li, e71t {- 8 yog ib qho kev tiv thaiv tus kheej ntau rau cov hlau me, thaum E308T-1 yog siv rau cov hlau stainless hauv fcaw.
Tig (tungsten inert roj) Vuam siv ib qho tsis - Consumable Tungsten Electrode, thiab cov xaim yog pub rau hauv lub pas dej weld. Cov xov hlau yog cov khoom siv thiab yuav tsum phim cov hlau hauv paus kom ze-}}}}}}} er88l rau stainless hlau nqaj welds. Lawv feem ntau muaj nyob rau hauv cov diam hlau me me rau kev tswj kom meej, ua rau lawv haum rau cov khoom siv nyias lossis cov khoom siv zoo nkauj.
Soj ntsuam xyuas cov cai thiab daim ntawv thov
Kev siv cov khoom siv welded welded dictectes cov hlau cov khoom siv thiab kev xav tau kev ua tau zoo.
Load - Cov kabmob pob qij txha xav tau cov xov hlau uas muaj lub zog siab thiab cuam tshuam. Piv txwv li, yog tias vuam crane boom (lub zog loj {} {{} {}}} Lub zog cored) yuav zoo dua li tus qauv er70s-6. Rau cov qauv hlau hauv cov vaj tse lossis cov choj, xov hlau yuav tsum ua kom tau raws li cov xov hlau (xws li AJBONS hlau xov hlau) los xyuas kom lawv tuaj yeem tiv thaiv cov qub thiab muaj zog.
Corrosion tsis kam yog qhov tseem ceeb rau velds nthuav tawm cov dej noo, tshuaj noj, lossis ntsev. Stainless hlau xaim (zoo li 316L) lossis nickel - Cov xov hlau alloy yog tsim nyog ntawm no, yog cov hlau hlau tsis muaj xeb. Hauv kev siv marine, piv txwv li, 316L Mig xo khub nrog cov pa thaiv cov roj uas txhim kho corrosion tsis kam yog qhov kev xaiv txheem.
High -} sov qhov chaw ib puag ncig (xws li pa roj lossis tso tawm) yuav tsum tau tawm tsam (deformation nyob rau hauv tshav kub) thiab oxidation. Nickel - cov xov hlau lossis cua sov} Tsis txhob tsim rau cov mob no, thaum lawv tswj lub zog thiab ruaj khov ntawm qhov kub.
Kev txiav txim siab zoo nkauj kuj tseem yuav ua lub luag haujlwm. Rau cov kev pom Welds (piv txwv li, hauv lub cev zoo nkauj lossis lub cev siv tsheb ua lag luam yog qhov ua kom huv, huv si. Tig xaim xaim, nrog lawv cov kev tswj lawv lub hom phiaj, feem ntau yog siv rau lub hom phiaj no, raws li lawv cov lus qhia tsawg thiab tso cai rau kev hnav khaub ncaws zoo nkauj, hnav tsoos tsho.
Txheeb co kab uas hla thiab sib xyaw
Cov hlau hlau cuam tshuam rau cov lus tawm thaum tshav kub, tso nyiaj rau, thiab muaj peev xwm nkag mus rau hauv cov hlau. Thicker xov hlau (0.023 "-0.035") ua haujlwm zoo tshaj plaws rau cov ntaub ntawv (0.245) yog qhov zoo dua rau cov ntaub ntawv 1/4 ".
Cov xaim yuav tsum tau sib haum nrog koj lub tshuab vuam. Feem ntau cov tshuab dhos ntau yam ntawm cov kab hlau uas lawv tuaj yeem ua (piv txwv li ntawm 0.023 ") Tsis tas li ntawd, cov hlau cooon yuav tsum haum lub tshuab cov kab yas ntu muaj ntau thiab 50-lb, lossis 50-lb spools rau mig xaim.
Txheeb xyuas cov qauv kev lag luam thiab cov lus qhia tshwj xeeb
Hauv kev lag luam tswj kev lag luam (xws li aerospace, tsheb, lossis roj thiab roj), cov qauv tshwj xeeb uas hais kom muab siv. Cov qauv no kom paub meej tias Welds ntsib kev nyab xeeb thiab kev ua tau zoo.
Piv txwv li, AWS (American Vuam Society) Cov qauv koom nrog cov khoom siv los ntawm lawv cov khoom: WISS A5.1, thaum ANS A5.9 qhia meej 5.9 qhia meej hom hlau hlau. Yog tias koj ua haujlwm ntawm ib qho haujlwm uas yuav tsum muaj ntawv pov thawj, cov xaim hlau yuav tsum muaj ntawv pov thawj rau AWS A5.14 (Ams (Aerospace cov qauv kev qhia tshwj xeeb) lossis cov qauv AERS).
Manufacturers 'cov lus qhia kuj tseem ceeb. Yog tias koj yog vuam ib hom hlau (piv txwv li, tus qauv HSLAYS HSLA), cov chaw tsim khoom yuav pom zoo kom muaj kev sib raug zoo thiab ua tau zoo. Tsis quav ntsej cov lus qhia no tuaj yeem tsis muaj kev tiv thaiv lossis kev ua kom muaj kev cuam tshuam Weld lub ncaj ncees.
Kuaj thiab kho
Txawm tias tom qab nqaim koj cov kev xaiv, nws yog qhov muaj peev xwm los ntsuas cov xaim ntawm ib daim ntawv ntawm cov hlau ua ntej pib txoj haujlwm kawg. Qhov no tso cai rau koj los kuaj xyuas cov teeb meem zoo li cov teeb meem tsis zoo, piv rau, lossis porosity, uas yuav qhia tau tias yog cov hlau thiab cov khoom siv / txheej txheem.
Piv txwv li, yog tias koj siv cov xaim xaim me me mig tab sis pom tias cov kab hlau loj heev rau cov khoom siv tuab, lossis cov pa roj sib xyaw tsis raug. Kho cov hlau (lossis cov tsis sib xws xws li voltage thiab hlau pub khoom noj kom ceev) raws li cov txiaj ntsig tau ua kom koj yuav tau txais kev ua tau zoo tshaj plaws ntawm qhov tseeb.
Hauv cov ntsiab lus, xaiv txoj cai vuam hlau cuam tshuam nrog cov hlau sib txuam, ua raws li kev sib koom ua ke nrog cov khoom siv thiab cov qauv, thiab kuaj qhov ua tau zoo. Los ntawm cov kab ke ntsuas cov khoom siv no, koj tuaj yeem xaiv cov xaim uas tsim muaj zog, cov phiaj xwm txhim khu kev qha
