Pipeline Kev Tsim Kho: SAW feem ntau yog ua haujlwm rau vuam kav ntev ntev vim nws qhov kev tso nyiaj siab thiab muaj peev xwm ua tiav cov vuam zoo hauv ib qho dhau los.
Structural Steel Fabrication: SAW yog siv rau vuam loj steel qauv, xws li txuas hniav, vaj tse, thiab kev lag luam moj khaum.
Heavy Machinery Manufacturing: SAW plays lub luag haujlwm tseem ceeb hauv kev tsim cov tshuab hnyav thiab cov khoom siv, ua kom muaj zog thiab txhim khu kev qha welds.
Railways thiab Tsheb thauj mus los: SAW yog ua haujlwm rau vuam railway rail, tsheb ciav hlau Cheebtsam, thiab lwm yam kev thauj mus los infrastructure.
Roj thiab Roj Kev Lag Luam: SAW feem ntau siv rau vuam cov roj thiab roj cia tank, cov kav dej, thiab cov chaw tawm sab nraud.
Cov khoom siv thiab khoom siv:
Txhawm rau ua submerged arc vuam, cov cuab yeej hauv qab no feem ntau yuav tsum tau:
Fais fab Source: Muab cov khoom siv hluav taws xob tsim nyog rau cov txheej txheem vuam.
Hlau Feeder: Muab cov khoom siv hluav taws xob siv hluav taws xob tsis tu ncua.
Vuam Lub taub hau: Tuav cov hlau electrode thiab coj nws raws li kev sib koom ua ke kom welded.
Flux Delivery System: Faib cov dej ntws tawm los tiv thaiv cov vuam arc thiab tsim cov slag tiv thaiv.
Flux Recovery Unit: Sau thiab rov ua dua cov flux siv rau kev ua haujlwm zoo.
Cov khoom siv siv hauv submerged arc vuam muaj xws li:
Vuam Hlau: Consumable electrode xov hlau muaj nyob rau hauv ntau yam compositions haum rau txawv daim ntaub ntawv thiab cov ntaub ntawv hauv paus.
Fluxes: Granular cov ntaub ntawv uas thaiv lub arc, muab kev tiv thaiv tiv thaiv atmospheric paug, thiab tsim cov slag los txhim kho weld zoo.
Ntxiv Alloying Elements: Nyob ntawm cov kev xav tau tshwj xeeb, cov ntsiab lus alloying ntxiv tuaj yeem raug ntxiv los txhim kho cov khoom siv vuam.
Kev coj ua zoo tshaj plaws rau Submerged Arc Vuam:
Txhawm rau ua tiav cov txiaj ntsig zoo nrog submerged arc vuam, cov kev coj ua zoo tshaj plaws yuav tsum tau xav txog:
Flux thiab Hlau Xaiv: Xaiv qhov tsim nyog ua ke ntawm flux thiab xaim raws li cov khoom siv welded thiab cov yam ntxwv uas xav tau weld.
Flux-rau-Wire Ratio: Ua kom muaj qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug los xyuas kom muaj kev tiv thaiv zoo thiab kev tswj hwm ntawm lub pas dej ua ke.
Base Metal Preparation: Ua ntej ntxuav kom txaus thiab npaj cov hlau hauv paus kom tshem tawm cov kab mob xws li roj, xeb, lossis nplai.
Welding Parameters Optimization: Txhim kho qhov vuam tsis zoo, suav nrog tam sim no, qhov hluav taws xob, thiab kev mus ncig ceev, kom ua tiav qhov xav tau weld yam ntxwv thiab nkag mus.
Cov Khoom Siv Kho: Tsis tu ncua tshuaj xyuas thiab tswj cov khoom siv vuam, nrog rau cov khoom siv hlau, cov lus qhia tiv tauj, thiab cov tshuab xa hluav taws xob, kom ntseeg tau tias kev ua haujlwm du thiab zoo sib xws.
Xaus:
