Cov txheej txheem arc vuam yog qhov tseem ceeb hauv kev tsim cov welded yeeb nkab, tshwj xeeb tshaj yog rau cov kav dej ntuj. Cov cuab yeej siv qhov kub thiab txias los tsim kev ruaj khov thiab ruaj khov ntawm cov kav dej, kom ntseeg tau tias cov kav dej tuaj yeem tiv taus qhov nruj ntawm daim ntawv thov. Txawm li cas los xij, zoo li txhua txoj kev tsim khoom, arc vuam muaj nws cov nyom. Feem ntau cov kav dej vuam tsis zoo tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm cov vuam, ua rau muaj peev xwm ua tsis tiav hauv thaj chaw. Kev nkag siab txog cov kev tsis zoo no thiab kev siv cov kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau cov tuam txhab tsim khoom, tshwj xeeb tshaj yog cov tuam txhab zoo li peb, nyob hauv Cangzhou, Hebei Xeev, uas yog thawj coj hauv kev lag luam txij li xyoo 1993.
Common yeeb nkab weld defects
1. Porosity: Qhov kev tsis zoo no tshwm sim thaum cov hnab ntim cua hauv qhov vuam, ua rau lub vuam tsis muaj zog. Porosity tuaj yeem tshwm sim los ntawm kev sib kis, ya raws, lossis cov txheej txheem vuam tsis raug.
2. Undercut: Thaum cov niam txiv hlau ntawm ntug ntawm cov weld melts, ib tug zawj yog tsim, ua rau cov weld tsis muaj zog. Qhov no feem ntau yog tshwm sim los ntawm overheating los yog tsis raug vuam ceev.
3. Inclusions: Cov no yog cov ntaub ntawv uas tsis yog-hlau uas tau ntes tau nyob rau hauv lub weld thiab tsis muaj zog weld. Kev suav nrog tuaj yeem los ntawm cov slag lossis lwm yam kab mob uas tsis raug tshem tawm ua ntej vuam.
4. Kev tawg: Kev tawg tuaj yeem tshwm sim hauvcev weldlos yog tshav kub-cuam tshuam cheeb tsam vim txias ceev, tsis tsim nyog muab tub lim cov ntaub ntawv los yog ntau weld kev nyuaj siab.
5. Fusion tsis txaus: Qhov kev tsis zoo no tshwm sim thaum lub vuam hlau tsis fuse txaus nrog niam txiv hlau, ua rau muaj kev sib koom ua ke tsis muaj zog. Qhov no tuaj yeem tshwm sim los ntawm cov cua sov tsis txaus lossis cov txheej txheem vuam tsis raug.
Yuav ua li cas tiv thaiv vuam tsis xws luag
Kev tiv thaiv cov yeeb nkab vuam tsis zoo no yuav tsum muaj kev cob qhia kom raug, kev tu cov cuab yeej siv, thiab ua raws li cov kev coj ua zoo tshaj plaws. Nov yog qee cov tswv yim uas koj tuaj yeem siv tau:
1. Kev cob qhia kom raug: Nws yog ib qho tseem ceeb los xyuas kom meej tias koj cov welds tau kawm zoo hauv cov txheej txheem arc vuam. Kev cob qhia tsis tu ncua tuaj yeem pab ua kom lawv nyob nrog cov kev coj ua tshiab thiab cov tswv yim tshiab.
2. Kev Tswj Xyuas Zoo: Kev siv lub zog tswj kev ua haujlwm zoo pab txhawm rau txheeb xyuas qhov tsis xws luag thaum ntxov ntawm cov txheej txheem tsim khoom. Kev tshuaj xyuas tsis tu ncua thiab kev ntsuas cov welds tuaj yeem kuaj pom cov teeb meem ua ntej lawv tsim teeb meem loj.
3. Kev Kho Cov Khoom Siv: Kev tu cov khoom siv vuam tsis tu ncua yog qhov tseem ceeb los xyuas kom muaj kev ua tau zoo. Qhov no suav nrog kev kuaj xyuas kom raug calibration, tu, thiab hloov cov khoom hnav.
4. Kev Npaj Khoom Siv: Kev npaj cov ntaub ntawv kom zoo ua ntej vuam tuaj yeem txo qhov kev pheej hmoo ntawm qhov tsis xws luag. Qhov no suav nrog kev ntxuav qhov chaw kom tshem tawm cov kab mob thiab ua kom cov khoom qhuav.
5. Tswj Ib puag ncig: Soldering nyob rau hauv ib puag ncig tswj tuaj yeem pab txo qhov kev pheej hmoo ntawm kev puas tsuaj los ntawm lwm yam xws li kub thiab av noo.
6. Siv cov ntaub ntawv zoo: Kev yuav cov khoom siv vuam zoo tuaj yeem txo qhov kev pheej hmoo ntawm qhov tsis xws luag. Qhov no suav nrog kev siv cov khoom muab tub lim tsim nyog thiab xyuas kom meej tias cov khoom siv niam txiv ua tau raws li qhov tseeb specifications.
Peb cov nroj tsuag hauv Cangzhou tsim 400,000 tons ntawm kauv hlau kav ib xyoos nrog 680 tus neeg ua haujlwm siab. Peb txoj kev cog lus rau kev ua tau zoo thiab kev tsim kho tshiab ua rau peb nyob rau hauv lub forefront ntawm kev lag luam. Los ntawm kev tsom mus rau kev tiv thaiv cov yeeb nkab vuam tsis xws luag, peb xyuas kom meej tias peb cov kav welded kauv, tshwj xeeb tshaj yog cov siv hauv cov raj xa hluav taws xob, ua tau raws li kev ntseeg siab tshaj plaws thiab cov qauv kev ua haujlwm.
Hauv cov ntsiab lus, kev nkag siab txog cov yeeb nkab vuam tsis xws luag thiab siv cov kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau cov tuam txhab lag luam hauv kev lag luam kauv welded yeeb nkab. Los ntawm qhov tseem ceeb ntawm kev ua tau zoo thiab kev cob qhia, cov tuam txhab tuaj yeem tsim cov khoom ruaj khov, txhim khu kev qha uas sawv qhov kev sim ntawm lub sijhawm.
