--Practical Judgement Methods Los ntawm "Pisible Observation" mus rau "Accurate Verification"
Nyob rau hauv cov txheej txheem ntawm kev yuav khoom ntawm ERW (Electric Resistance Welded) steel kav, weld zoo yeej ib txwm yog ib qho ntawm cov ntsiab lus tseem ceeb uas cov neeg yuav khoom them rau feem ntau, thaum tseem muaj feem ntau yuav to taub yuam kev. Raws li ERW steel kav yog longitudinal tsis kam welded steel kav, lawv cov welds tsis tu ncua faib raws axial kev taw qhia ntawm lub cev yeeb nkab. Vuam zoo yog cuam tshuam ncaj qha rau cov yeeb nkab lub siab- cov kabmob muaj peev xwm, kev ruaj ntseg ntawm cov qauv, thiab ntev- kev pabcuam kev nyab xeeb.
Txawm li cas los xij, rau feem ntau cov neeg yuav khoom, welds tsis yog qhov ntsuas tau zoo. Yuav ua li cas rau kev tshawb fawb thiab rationally soj ntsuam cov weld zoo theem ntawm ERW steel kav yam tsis muaj kev nkag tau mus rau ntau lawm tej yam kev mob yog ib tug tswv yim thiab tsim nyog engineering cognition teeb meem.
Los ntawm ntau qhov ntev xws li kev txheeb xyuas qhov pom, cov ntaub ntawv thev naus laus zis, kev sim, thiab lub peev xwm ntawm tus neeg muag khoom, kab lus no tau txhais cov ntsiab lus tseem ceeb rau kev txiav txim siab vuam zoo thaum yuav ERW steel kav.
I. Ua ntej, tsim kom muaj kev paub txog qhov chaw: Welds tsis sib npaug rau Kev Nyab Xeeb Zoo
Ua ntej txiav txim siab qhov zoo, cov neeg yuav khoom thawj zaug yuav tsum tsim kom muaj kev paub zoo: cov welds ntawm ERW steel kav lawv tus kheej tsis yog "tsis zoo" tab sis lub hom phiaj ntawm txoj kev tsim khoom.
Raws li cov txheej txheem paub tab, tom qab cua sov txaus, extrusion, thiab tom qab- vuam kev kho mob, cov khoom siv ntawm ERW steel yeeb nkab welds tuaj yeem ncav cuag lossis sib npaug rau lub hauv paus hlau. Kev pheej hmoo ntawm engineering tsis yog los ntawm "txawm tias muaj welds" tab sis los ntawm "txawm tias cov welds tau tswj tau zoo."
Yog li ntawd, lub hom phiaj ntawm kev txiav txim yuav khoom yuav tsum yog nyob rau hauv lub weld tswj theem, tsis yog weld daim ntawv nws tus kheej.
II. Pib nrog Qhov tshwm sim: Dab tsi tuaj yeem pom los ntawm Weld Surface?
Txawm hais tias qhov zoo ntawm cov welds cia siab rau txoj kev sim, qhov zoo li qhov weld tseem yog qhov yooj yim tshaj plaws thiab yooj yim overlooked thawj qhov kev txiav txim siab.
Siab - zoo ERW steel yeeb nkab welds feem ntau muaj cov yam ntxwv hauv qab no:
- Txoj haujlwm vuam yog ncaj thiab txuas ntxiv, tsis muaj kev sib txawv ntawm serpentine;
- Weld qhov siab yog ib yam, tsis muaj qhov pom tseeb protrusions lossis kev nyuaj siab;
- Qhov chaw weld nto yog tiaj tus, hloov pauv ib txwm nrog cov yeeb nkab lub cev.
Yog hais tias qhov chaw weld muaj qhov pom tseeb undercuts, cov hlaws tsis txuas ntxiv, lub hauv paus blackening, lossis ablation marks, nws feem ntau qhia tias tsis ruaj khov txheej txheem vuam. Txawm tias qhov kev sim tom ntej dhau los, yuav tsum tau ceev faj.
Nws yuav tsum raug sau tseg tias qhov tsim nyog zoo li tsis tas txhais tau tias siab - zoo welds, tab sis qhov txawv txav yuav luag yeej qhia tau tias muaj kev pheej hmoo sab hauv.
III. Txiav txim qhov Weld Control Logic Los ntawm txheej txheem piav qhia
Ua ntej kev yuav khoom, kev nkag siab txog cov txheej txheem vuam ntawm tus neeg muag khoom ERW steel kav yog ib txoj hauv kev tseem ceeb los txiav txim siab qib vuam zoo.
Mature ERW steel yeeb nkab ntau lawm feem ntau qhia meej meej cov ntsiab lus hauv qab no:
- Txawm hais tias siab - zaus induction welding tau txais yuav;
- Seb puas yog ib qho ruaj khov extrusion forming system yog configured;
- Seb puas yog ib qho ntawm -kab vuam txheej txheem kev kho cua sov sib phim.
Ntawm cov no, tom qab-weld kev kho cua sov yog qhov tseem ceeb heev. Los ntawm kev ua haujlwm ntawm -kab lossis tawm- kab kev kho cua sov ntawm qhov vuam thiab cua sov- thaj chaw cuam tshuam, cov qauv tuaj yeem ua kom zoo dua qub, vuam qhov seem ntawm kev ntxhov siab tshem tawm, thiab kev ua haujlwm vuam ua kom ruaj khov dua. Cov txheej txheem no feem ntau yog ib qho tseem ceeb qhia qhov txawv ntawm ERW steel yeeb nkab los ntawm siab - zoo ERW steel kav.
Yog tias tus neeg muag khoom tsis tuaj yeem piav qhia meej txog qhov vuam thiab tom qab - vuam kev kho cov logic, feem ntau txhais tau hais tias lawv qhov kev tswj xyuas qhov zoo ntawm vuam tsis paub tab.
IV. Ua kom pom tseeb ntawm Weld-Cov khoom ntsuas cuam tshuam
Hauv cov ntaub ntawv thev naus laus zis thiab cov ntaub ntawv pov thawj zoo, cov neeg yuav khoom yuav tsum tsom mus rau seb qhov vuam puas raug kuaj raws li cov khoom siv ywj pheej, tsis yog kev ntsuas kev ua tau zoo tag nrho.
Cov txheej txheem kev ntsuas vuam uas muaj txiaj ntsig thiab muaj txiaj ntsig suav nrog: ntawm - kab ntsuas ultrasonic, eddy tam sim no kuaj, thiab qhov tsim nyog qhov chaw kuaj hluav taws xob. Cov kev sim no tuaj yeem tshawb xyuas qhov cuam tshuam hauv cov vuam xws li tsis tiav fusion, tawg, lossis kev suav nrog.
Nyob rau tib lub sijhawm, kev saib xyuas kuj yuav tsum tau them rau seb cov yeeb nkab steel puas tau dhau los ntawm kev ntsuas cov khoom siv ze ze rau cov welds, xws li kev ntsuam xyuas flattening thiab flaring tests. Cov kev ntsuam xyuas zoo li no tuaj yeem cuam tshuam ncaj qha rau kev ntseeg tau ntawm cov vuam nyob rau hauv cov yas deformation thiab yog cov pov thawj tseem ceeb ntawm kev vuam zoo.
Rau ERW steel kav siv rau siab-cov kabmob lossis cov qauv tsim, qhov ntsuas qhov ntsuas qhov ntsuas thiab cov qauv ntsuas feem ntau yog siv ntau dua li cov txiaj ntsig kev xeem ib zaug.
V. Tus Kws Txiav Txim Weld Cov Kev Xav Tau Zoo Raws li Kev Pabcuam Scenarios
Weld zoo txiav txim tsis tuaj yeem raug cais los ntawm kev siv engineering tshwj xeeb. Cov xwm txheej sib txawv muaj qhov sib txawv tseem ceeb hauv kev xav tau rau ERW steel yeeb nkab welds.
Piv txwv li, ERW steel kav siv rau cov qauv dav dav lossis qis - kev sib kis kev sib kis tau tsom mus rau qhov sib xws thiab kev ruaj ntseg tag nrho; thaum cov uas siv rau cov kav dej hauv nroog, kev sib kis ntawm cov kua dej, thiab lwm yam xwm txheej muaj kev xav tau ntau dua rau kev sib tsoo thiab kev qaug zog.
Yog li ntawd, thaum txiav txim siab qhov zoo ntawm vuam, cov neeg yuav khoom yuav tsum ua kom haum raws li qhov kev tswj xyuas vuam raws li cov txheej txheem engineering xws li kev tsim siab, cov yam ntxwv nruab nrab, thiab kev pabcuam lub neej, tsis yog qhov muag tsis pom kev "ntau yam tshwj xeeb."
VI. Infer Weld Quality Level los ntawm Supplier Capabilities
Hauv kev yuav khoom tiag tiag, weld zoo tsis tuaj yeem txiav txim siab los ntawm ib lub yeeb nkab steel; nws yuav tsum tau muaj kev ntsuam xyuas tag nrho ntawm tus neeg muag khoom lub peev xwm tag nrho.
ERW steel yeeb nkab manufacturers nrog ruaj khov weld zoo feem ntau muaj cov yam ntxwv hauv qab no:
- Qib siab ntawm automation hauv cov khoom siv ntau lawm;
- Zoo meej txheej txheem parameter tswj system;
- Ua kom tiav cov txheej txheem xeem thiab cov txheej txheem txheem;
- Ntev -lub sij hawm thiab rov ua dua cov khoom siv rau cov haujlwm loj -.
Piv nrog rau kev sib dhos ib ntus lossis me me - cov kab ntau lawm, cov tuam txhab lag luam nrog cov txheej txheem paub tab muaj kev ruaj ntseg ntau dua thiab kev ua tau zoo ntawm cov vuam zoo.
Xaus
Rau cov neeg yuav khoom, kev txiav txim siab qhov zoo ntawm ERW steel kav tsis yog nyob ntawm ib qho kev qhia lossis ib daim ntawv qhia ib zaug xwb, tab sis yog cov txheej txheem kev soj ntsuam zoo. Los ntawm kev soj ntsuam zoo, kev nkag siab ntawm cov txheej txheem, kev soj ntsuam xyuas, thiab kev soj ntsuam kev muaj peev xwm ntawm tus neeg muag khoom, nws muaj peev xwm txiav txim siab seb qhov vuam zoo li cas raws li qhov xav tau ntawm engineering.
Hauv kev tsim kho vaj tse, xaiv cov tuam txhab lag luam nrog kev paub txog kev tswj cov vuam thiab kev ruaj ntseg engineering yog ib qho tseem ceeb los txo qhov kev pheej hmoo ntawm kev yuav khoom thiab ua kom muaj kev nyab xeeb ntawm qhov project. Kev cob qha ERW steel yeeb nkab manufacturers sawv cev los ntawm Huayang Steel Yeeb Nkab tau muab cov khoom lag luam ruaj khov thiab txhim khu kev qha steel yeeb nkab rau ntau yam haujlwm engineering los ntawm kev ua haujlwm ntev - lub sij hawm tswj qhov zoo ntawm vuam zoo.
