Yog lawm,Galvanized hlau (GI) kavtuaj yeem welded. Txawm li cas los xij, muaj qee qhov kev xav tseem ceeb uas yuav tsum nco ntsoov thaum vuam GI kav vim muaj cov zinc txheej ntawm lawv qhov chaw. Cov zinc txheej ntawm GI kav yog siv los tiv thaiv cov hlau los yog hlau los ntawm corrosion. Vuam tuaj yeem cuam tshuam rau cov zinc txheej no thiab cov khoom nyob ib puag ncig, yog li nws yog qhov tseem ceeb uas yuav tsum tau ceev faj tshwj xeeb:
Qhov cua kom raug: Thaum vuam GI kav, xyuas kom meej tias koj ua hauj lwm nyob rau hauv ib tug zoo-ventilated cheeb tsam los yog siv lub tso pa tawm hauv zos. Vuam ntawm cov ntaub ntawv galvanized tuaj yeem tso cov pa hluav taws xob zinc, uas tuaj yeem ua rau muaj kev phom sij yog tias nqus tau.
Zinc Vapor Avoidance: Txo qhov raug zinc fumes los ntawm vuam nrog cov txheej txheem kom raug. Tsis txhob tso cua sov ntau dhau, uas tuaj yeem vaporize zinc txheej. Vuam kub dhau tuaj yeem ua rau muaj cov pa taws ntau ntxiv thiab kev puas tsuaj rau zinc txheej.
Cov txheej txheem vuam zoo: Xaiv cov txheej txheem vuam uas haum rau GI kav. Cov txheej txheem vuam uas siv rau cov kav dej GI suav nrog MIG (Metal Inert Gas) vuam lossis TIG (Tungsten Inert Gas) vuam. Cov txheej txheem no tso cai rau kev tswj kom zoo dua ntawm cov cua sov nkag.
Kev npaj: Ntxuav cov GI yeeb nkab kom huv si ua ntej vuam. Tshem tawm cov av, roj, lossis cov khoom paug tawm ntawm qhov chaw vuam kom ntseeg tau tias qhov vuam huv.
Vuam Consumables: Siv vuam consumables (electrodes, xov hlau, los yog cov ntaub ntawv muab tub lim) uas yog tsim tshwj xeeb rau vuam ntawm galvanized nto. Cov khoom siv no yog tsim los muab qhov chaw ruaj khov thiab txo qis kev puas tsuaj rau zinc txheej.
Vuam Tshuab: Siv cov txheej txheem vuam kom zoo kom txo tau qhov kub ntawm qhov cuam tshuam (HAZ) thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj rau zinc txheej. Tswj lub arc ntev thiab taug kev ceev kom tswj tau cov cua kub nkag.
Tom qab Weld Inspection: Tom qab vuam, tshuaj xyuas qhov vuam thiab qhov chaw ib puag ncig kom pom tias muaj kev puas tsuaj rau cov zinc txheej. Xyuas kom meej tias cov weld yog lub suab zoo thiab tsis muaj qhov pom kev tsis zoo.
Kev tiv thaiv nto: Yog tias cov zinc txheej raug cuam tshuam rau lub sijhawm vuam, xav txog kev siv cov zinc-nplua nuj xim los yog txheej rau qhov chaw welded los muab kev tiv thaiv ntxiv tiv thaiv corrosion.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias vuam GI kav yuav nyuaj dua li cov kav hlau tsis muaj coated vim muaj cov zinc txheej. Yog li ntawd, nws raug nquahu kom muaj kev paub txog kev vuam thiab ua tib zoo saib xyuas kev nyab xeeb thaum ua haujlwm nrog cov khoom siv galvanized. Tsis tas li ntawd, yuav tsum paub txog cov kev phom sij uas cuam tshuam nrog kev vuam ntawm qhov chaw galvanized, xws li tso cov pa hluav taws xob zinc, thiab ntsuas kev tiv thaiv koj kev noj qab haus huv thaum vuam.
