1. Q: Qhov kev npaj dab tsi ua ntej vuam attm A335 p5 steel yeeb nkab?
A: Npaj ua ntej vuam pull p5 steel yeeb nkab yog qhov tseem ceeb thiab thawj kauj ruam los ua kom ua kom zoo nkauj weld zoo. Ua ntej, qhov zawj thiab thaj chaw ib puag ncig nws, tsawg kawg 25mm ntawm ob tog, yuav tsum tau huv si kom tshem tag nrho cov impurities xws li roj, xeb, noo noo, thiab pleev xim. Cov tshuaj no yog cov ua kom pom tseeb ntawm porosity thiab hydrogen -} ua rau tawg. Thib ob, grection groove (xws li v {{6} {} zoo li tus zeem muag kom ua kom muaj kev nkag siab txaus thiab kev sib sau ua ke ntawm cov khoom weld txaus. Vuam cov pas nrig yuav tsum yog muab ziab nruj raws li cov lus qhia kom zoo, siv lub qhov cub kom qhuav thiab cov twj vov kev nqus hauv Weld. Thaum kawg, yog yuav tsum yog yog tias tsim nyog. Cov kev pom zoo preheating kub yog feem ntau yog nruab nrab ntawm 150-200 ° C kom txo tau cov cua txias thiab muaj kev ntxhov siab nyob hauv weld sib koom tes.
2. Q: Dab tsi ntawm welding cov khoom siv yog feem ntau siv rau vuam p5 steel yeeb nkab?
A: Txhawm rau kom paub meej tias kev ua tau zoo weld phim cov khoom siv ntawm niam txiv, tshwj xeeb yog cov tshuaj sib piv nrog vuam p5 steel yeeb nkab. For manual metal arc welding (SMAW), AWS E5XX-XX (such as E505-15) low-hydrogen electrodes are typically used, with the Cr-Mo content of the deposited metal matching that of P5. Rau tungsten inert roj vuam (gtaw / tig), er50s prof hlau feem ntau siv rau lub hauv paus kis kom ntseeg tau tias lub hauv paus tsim thiab zoo. Rau submerged arc vuam (pom) lossis flux-} cored arc vuam (FCAW), ua ke kuj tseem yuav tsum tau ua ke. Tag nrho cov vuam no yuav tsum tau ua kom muaj lub xeev muaj dej tsawg thiab ua raws li cov chaw tsim khoom cov lus qhia.
3 Dab tsi yog cov tseem ceeb tsis yog? A: Tshaj tawm - Weld Kev Kho Cua Sov (PWHT) yog yuav tsum tau rau P5 Steel Yeeb Nkab. Nws cov hom phiaj tseem ceeb yog peb zaug: Ua ntej, kom tshem tawm cov kev ntxhov siab uas muaj ntau tsim rau thaum lub sijhawm vuam, tiv thaiv kev ntxhov siab corrosion; Thib ob, kom siab tag nrho lub zog thiab nkig martensite, hloov nws mus rau ntau lub hardness temped, yog li txo lub hardness temped, yog li txo lub hardness ntawm tshav kub} be} cuam tshuam cheeb tsam (Haz); Thiab qhov thib peb, kom pab txhawb hydrogen diffusion thiab khiav dim, kiag li tshem tawm txoj kev pheej hmoo ntawm hydrogen {}}}} induced qeeb. Cov kev tsis tseem ceeb suav nrog kev kho cua sov (feem ntau tswj tau ntawm ib teev (feem ntau yuav raug muab tso rau hauv ib teev (feem ntau yuav tsum tau ua kom sov thiab cua txias, feem ntau txwv tsawg dua 150 ° C / teev). Qhov kub yuav tsum tau nyob thoob plaws tag nrho Weld sib koom ua ke.
4. Q: Yuav tsum ceev faj dab tsi thaum siv lub tshuab nyem steel?
A: Thaum machining p5 steel yeeb nkab, nws yog ib qho tseem ceeb kom paub txog cov kev cov nyom tau nthuav tawm los ntawm nws cov khoom alloy. Vim nws lub zog siab thiab qee yam nyuaj, tshuab ua kom txaus rigidity thiab lub zog nyob rau hauv lub tshuab cuab tam, fixture, thiab kev ua vaj tse, thiab kev ua vaj tse system. Nws raug nquahu kom siv cov cuab yeej carbide thiab xaiv cov cuab yeej carmetry thiab txiav, thiab qhov tob ntawm txiav) kom ua tiav qhov sib npaug ntawm kev siv lub tshuab ua haujlwm zoo thiab cuab tam lub neej. Ua kom txias thiab lubrication yog qhov tseem ceeb; Lawv tsis tsuas yog dissipate txiav tshav kub, tiv thaiv kev ua haujlwm overheating thiab ua haujlwm hnyav, tab sis kuj tseem txhim kho qhov chaw ua tiav ntawm cov tshuab ua tiav. Rau kev tig thiab drilling, siv chipreaker cov cuab yeej pab tswj cov chips thiab paub meej tias kev ua haujlwm nyab xeeb.

A: COG Bend radius yuav feem ntau tsis yog tsawg tshaj peb zaug cov yeeb nkab sab nraud ntawm lub taub. Kev khoov me me me me tuaj yeem ua rau muaj cov phab ntsa ntau dhau los yog wrinkling. Ib qho yeeb nkab cov yeeb nkab puas yog siv rau cov txheej txheem khoov kom ntseeg tau tias muaj kev sib luag thiab kev ua kom loj thiab khawb sab saum toj. Tom qab kev khoov txias, kev kho cua sov feem ntau tsis tas, tab sis cov phab ntsa tuab txo qis (feem ntau tsis muaj ntau tshaj 15% ntawm cov nominal phab ntsa tuab) thiab ovality nyob rau hauv thaj chaw khoov yuav tsum tau kuaj. Yog tias qhov kev txhawj xeeb txias no loj heev lossis muaj cov kev cai tshwj xeeb hauv cov qauv, kev pab txhawb kev ntxhov siab.
