1. Q195 welded kav puas tuaj yeem siv rau kev txhawb nqa?
Q195 welded kav yuav siv tau rau kev txhawb nqa lub teeb, xws li scaffolding me me, kev txhawb nqa ib ntus, thiab lub teeb thav duab. Txawm li cas los xij, lawv tsis haum rau kev txhawb nqa hnyav (xws li lub tsev loj thav duab) vim lawv lub zog qis.
2.Dab tsi yog qhov txawv ntawm kev xaiv cov khoom siv vuam ntawm Q215 thiab Q235 welded kav?
Rau Q215 welded kav, vuam cov ntaub ntawv nrog lub zog sib xws (xws li E43 series electrodes rau MMAW) feem ntau yog xaiv; rau Q235 welded kav, E43 lossis E50 series electrodes tuaj yeem siv. Kev xaiv tshwj xeeb yog nyob ntawm txoj kev vuam thiab qhov yuav tsum tau muaj zog vuam. Feem ntau, lub zog ntawm cov khoom siv vuam yuav tsum siab dua me ntsis ntawm cov hlau puag.
3. Puas yog Q195, Q215, thiab Q235 welded kav yuav tsum tau kho cua sov tom qab vuam?
Feem ntau, lawv tsis xav tau tom qab- vuam kev kho cua sov. Vim lawv cov weldability zoo, qhov seem seem tom qab vuam yog qhov me me, uas yuav tsis cuam tshuam rau kev ua haujlwm. Txawm li cas los xij, rau tuab- cov kav dej lossis cov kav dej uas siv rau hauv siab - qhov chaw muaj kev ntxhov siab, kev kho cua sov yuav tsum tau ua kom txo qis kev ntxhov siab.
4. Lub neej kev pab cuam ntawm Q235 galvanized welded kav yog dab tsi?
Lub neej kev pab cuam ntawm Q235 galvanized welded kav nyob ntawm ib puag ncig. Hauv qhov chaw qhuav hauv tsev, lub neej kev pabcuam tuaj yeem ncav cuag 20-30 xyoo; nyob rau sab nraum zoov ntub lossis corrosive ib puag ncig (xws li thaj chaw ntug dej hiav txwv), kev pabcuam lub neej feem ntau yog 10-20 xyoo. Kev saib xyuas tsis tu ncua thiab kev tiv thaiv corrosion tuaj yeem ua rau lub neej ua haujlwm ntev.
5. Dab tsi yog qhov tsis zoo ntawm Q195, Q215, thiab Q235 welded kav, thiab yuav ua li cas kom tsis txhob muaj lawv?
Cov khoom tsis zoo xws li cov kab nrib pleb, qhov pores, slag inclusions, incomplete penetration, thiab yeeb nkab deformation. Txhawm rau zam lawv: 1) Siv cov khoom tsim nyog hauv cov hlau thiab cov khoom siv vuam; 2) Txhim kho cov txheej txheem vuam (tswj vuam tam sim no, voltage, thiab ceev); 3) Ua ntej- vuam tu (tshem xeb, roj, thiab oxide nplai); 4) Ua kev soj ntsuam nruj zoo tom qab vuam; 5) Tsis txhob muaj kev ntxhov siab ntau dhau thaum lub sij hawm tsim cov yeeb nkab.
