Dab tsi yog hlau zoo? Tshwj tsis yog tias koj txaus siab kawm txog metallurgy, qhov no tsis yooj yim los teb. Tab sis, los muab nws yooj yim, kev tsim cov hlau zoo yog nyob ntawm hom thiab qhov zoo ntawm cov alloys siv, cua sov, cua txias thiab ua cov txheej txheem, thiab cov txheej txheem tsim khoom uas koom nrog lub tuam txhab tsis pub lwm tus paub.
Rau cov laj thawj no, koj yuav tsum muaj peev xwm vam khom lub hauv paus ntawm koj lub kauj los pab kom ntseeg tau tias qhov zoo thiab qhov ntau ntawm cov hlau koj xav tias koj xaj yog raws li qhov zoo thiab qhov ntau ntawm cov hlau koj tau txais tiag tiag.
Cov tswv ntawm yob txoj kev tshuab uas yog portable thiab nyob rau hauv khw muag khoom ruaj machines tej zaum yuav tsis paub hais tias txhua specification muaj ib tug pub yuag ntau yam, thiab tsis xav txog qhov no thaum txiav txim tej zaum yuav ua rau kom poob ceeb thawj.
Ken McLauchlan, Tus Thawj Coj ntawm Kev Muag Khoom ntawm Drexel Metals hauv Colorado, piav qhia: "Thaum phaus ib square feet nyob rau hauv qhov kev tso cai, nws tuaj yeem nyuaj rau xaj cov ntaub ntawv vov tsev los ntawm phaus thiab muag los ntawm square feet." “Koj tuaj yeem npaj dov cov khoom. Teem ntawm 1 phaus ib square feet, thiab lub kauj xa tawm yog nyob rau hauv kev ua siab ntev ntawm 1.08 phaus ib square feet, mam li nco dheev, koj yuav tsum ua kom tiav qhov project thiab tau them rau cov khoom tsis txaus los ntawm 8%.
Yog tias koj khiav tawm, koj puas tau txais lub ntim tshiab raws li cov khoom koj tau siv? McLauchlan tau muab ib qho piv txwv ntawm nws qhov kev ua haujlwm dhau los ua tus neeg ua haujlwm loj vov tsev. Tus neeg cog lus tau hloov qhov nruab nrab ntawm qhov project los ntawm kev siv prefabricated panels los yob ua nws tus kheej panels ntawm qhov chaw. Cov coils lawv xa khoom nyuaj dua li cov uas siv thiab xav tau rau txoj haujlwm. Txawm hais tias cov hlau zoo, cov hlau hnyav tuaj yeem ua rau cov kaus poom roj ntau dhau.
Hais txog qhov teeb meem ntawm cov kaus poom roj, McLaughlin tau hais tias, “Ib txhia ntawm lawv tej zaum yuav yog [yob sib sau] tshuab-lub tshuab tsis raug kho; ib co ntawm lawv tej zaum yuav coils-cov kauj yog nyuaj tshaj li nws yuav tsum tau; los yog nws tuaj yeem yog qhov sib xws: Kev sib raug zoo tuaj yeem yog qib, specification, thickness, lossis hardness. "
Kev tsis sib haum xeeb tuaj yeem tshwm sim thaum ua haujlwm nrog ntau tus neeg muag khoom. Nws tsis yog qhov zoo ntawm cov hlau tsis zoo, tab sis qhov kev ntsuas thiab kev sim ua los ntawm txhua lub chaw tsim khoom ua tau raws li nws lub tshuab thiab nws cov kev xav tau. Qhov no siv rau cov peev txheej steel, nrog rau cov tuam txhab ntxiv cov xim thiab xim. Lawv txhua tus tuaj yeem nyob hauv kev lag luam tolerances / cov qauv, tab sis thaum sib xyaw thiab sib piv cov neeg xa khoom, cov kev hloov pauv hauv cov txiaj ntsig los ntawm ib qho mus rau lwm qhov yuav cuam tshuam txog cov khoom kawg.
"Los ntawm peb qhov kev xav, qhov teeb meem loj tshaj plaws rau cov khoom tiav yog [txheej txheem thiab kev sim] yuav tsum zoo ib yam," McLaughlin tau hais. "Thaum koj muaj qhov tsis sib xws, nws dhau los ua teeb meem."
Yuav ua li cas thaum lub vaj huam sib luag tiav muaj teeb meem ntawm qhov chaw ua haujlwm? Vam tias nws yuav raug ntes ua ntej kev teeb tsa, tab sis tshwj tsis yog tias qhov teeb meem pom tseeb thiab lub ru tsev muaj kev mob siab rau hauv kev tswj kom zoo, nws yuav tshwm sim tom qab lub ru tsev tau teeb tsa.
Yog tias tus neeg siv khoom yog thawj zaug pom lub vaj huam sib luag wavy lossis xim hloov, lawv yuav hu rau tus neeg cog lus thawj zaug. Cov neeg cog lus yuav tsum hu rau lawv cov neeg muab khoom vaj huam sib luag lossis, yog tias lawv muaj cov tshuab ua yob, lawv cov chaw xa khoom coil. Qhov zoo tshaj plaws, lub vaj huam sib luag lossis cov khoom siv coil yuav muaj txoj hauv kev los ntsuas qhov xwm txheej thiab pib cov txheej txheem ntawm kev kho nws, txawm tias nws tuaj yeem taw qhia tias qhov teeb meem nyob hauv kev teeb tsa, tsis yog lub kauj. McLaughlin tau hais tias "Txawm hais tias nws yog ib lub tuam txhab loj lossis ib tus neeg ua haujlwm sab nraum nws lub tsev thiab chaw nres tsheb, nws xav tau ib lub chaw tsim khoom los sawv tom qab nws," McLaughlin tau hais. "Cov neeg cog lus dav dav thiab cov tswv tab tom saib cov neeg ua haujlwm vov tsev zoo li lawv tau tsim teeb meem. Qhov kev cia siab yog qhov sib txawv yog tias cov chaw muag khoom, cov chaw tsim khoom, yuav muab cov ntaub ntawv ntxiv lossis kev txhawb nqa. "
Piv txwv li, thaum Drexel raug hu rau hauv, McLauchlan piav qhia, "Peb tau mus rau qhov chaw ua haujlwm thiab hais tias, "Hav, qhov ua rau qhov teeb meem no, puas yog qhov teeb meem substrate (décor), teeb meem hardness, lossis lwm yam?; Peb tab tom sim ua kev txhawb nqa Back-office ... thaum cov tuam txhab tsim tawm, nws coj kev ntseeg siab. "
Thaum qhov teeb meem tshwm sim (nws yuav twv yuav raug hu ib hnub), koj yuav tsum xyuas seb yuav ua li cas nrog ntau yam teeb meem ntawm lub vaj huam sib luag los ntawm point A mus rau point B. Khoom siv; Nws puas tau kho nyob rau hauv lub tolerances ntawm lub tshuab; puas haum rau txoj haujlwm? Koj puas tau yuav cov khoom siv tshwj xeeb uas muaj qhov zoo hardness; puas muaj kev ntsuam xyuas rau cov hlau los txhawb qhov xav tau?
"Tsis muaj leej twg xav tau kev sim thiab kev txhawb nqa ua ntej muaj teeb meem," McLaughland tau hais. "Tom qab ntawd nws feem ntau yog vim muaj ib tus neeg hais tias, 'Kuv tab tom nrhiav tus kws lij choj, thiab koj yuav tsis tau them nyiaj."
Muab qhov kev lees paub zoo rau koj lub vaj huam sib luag yog ib txoj hauv kev los ua koj tus kheej lub luag haujlwm thaum muaj xwm txheej phem. Lub Hoobkas muab lub hauv paus hlau (liab xeb perforated) warranty. Lub tuam txhab pleev xim muab kev lees paub rau kev ncaj ncees ntawm cov yeeb yaj kiab txheej. Qee cov neeg muag khoom, xws li Drexel, muab cov kev lees paub rau hauv ib qho, tab sis qhov no tsis yog ib qho kev coj ua. Paub tias koj tsis muaj ob leeg tuaj yeem ua rau mob taub hau loj.
McLaughlin tau hais tias "Muaj ntau qhov kev lees paub uas koj pom hauv kev lag luam yog prorated lossis tsis yog (xws li substrate lossis tsuas yog kev lees paub txog kev ncaj ncees)," McLaughlin tau hais. "Qhov no yog ib qho ntawm cov kev ua si uas lub tuam txhab ua si. Lawv yuav hais tias lawv yuav muab koj ib zaj duab xis kev ntseeg siab guarantee. Ces koj muaj ib tug tsis ua hauj lwm. Cov khoom siv hlau substrate hais tias nws tsis yog hlau tab sis xim; tus neeg pleev kob hais tias nws yog hlau vim nws yuav tsis lo. Lawv taw tes rau ib leeg. . Tsis muaj ib yam dab tsi phem dua li ib pawg neeg ntawm qhov chaw ua haujlwm liam ib leeg. "
Los ntawm tus neeg cog lus uas teeb tsa lub vaj huam sib luag rau lub tshuab yob txoj kev uas yob lub vaj huam sib luag, mus rau yob txoj kev tshuab siv los tsim lub vaj huam sib luag, mus rau cov xim pleev xim thiab ua tiav rau lub kauj, mus rau lub Hoobkas uas tsim cov kauj thiab tsim cov hlau los ua. lub coil. Nws siv kev sib koom tes muaj zog los daws cov teeb meem sai sai ua ntej lawv tawm ntawm kev tswj hwm.
McLauchlan xav kom koj tsim kom muaj kev sib koom tes nrog cov tuam txhab uas muab cov kev pabcuam zoo tshaj plaws rau koj cov panels thiab coils. Kev lees paub tsim nyog yuav raug xa rau koj los ntawm lawv cov channel. Yog tias lawv yog cov neeg koom tes zoo, lawv kuj yuav muaj peev txheej los txhawb cov kev lees paub no. McLauchlan tau hais tias es tsis txhob txhawj xeeb txog ntau qhov kev lees paub los ntawm ntau qhov chaw, tus khub zoo yuav pab sau cov warranty, "yog li yog tias muaj teeb meem lav," McLauchlan tau hais tias, "qhov no yog warranty, tus neeg hu, lossis raws li peb hais. nyob rau hauv kev lag luam, ib tug choked caj pas. "
Yooj yim warranty tuaj yeem muab rau koj nrog qee qhov kev ntseeg siab muag. "Qhov tseem ceeb tshaj plaws uas koj muaj yog koj lub koob npe nrov," McLaughlin hais ntxiv.
Yog tias koj muaj ib tus khub txhim khu kev qha tom qab koj, los ntawm kev tshuaj xyuas thiab kev daws teeb meem ntawm qhov teeb meem, koj tuaj yeem ua kom cov lus teb sai thiab txo qhov mob tag nrho. Tsis txhob qw ntawm qhov chaw ua haujlwm, koj tuaj yeem pab ua kom muaj kev thaj yeeb nyab xeeb raws li qhov teeb meem tab tom daws.
Txhua tus neeg nyob hauv cov saw hlau muaj lub luag haujlwm los ua tus khub zoo. Rau yob txoj kev tshuab, thawj kauj ruam yog mus yuav cov khoom zoo los ntawm kev txhim khu kev qha. Qhov kev ntxias loj tshaj plaws yog coj txoj kev pheej yig tshaj plaws.
McLaughland tau hais tias, "Kuv tau sim txhim kho tus nqi kom zoo," tab sis thaum tus nqi ntawm qhov teeb meem yog 10 npaug siab dua tus nqi txuag, koj pab tsis tau koj tus kheej. Nws zoo li yuav 10% luv nqi ntawm cov khoom thiab tom qab ntawd 20% paj laum yuav muab tso rau hauv koj daim npav rho nyiaj. "
Txawm li cas los xij, nws tsis muaj txiaj ntsig kom muaj lub kauj zoo tshaj plaws yog tias nws tsis ua haujlwm zoo. Kev tu lub tshuab zoo, kev tshuaj xyuas niaj hnub, kev xaiv kom raug ntawm cov profiles, thiab lwm yam, txhua tus ua lub luag haujlwm tseem ceeb thiab yog tag nrho ntawm lub luag haujlwm ntawm lub tshuab yob.
Xyuas kom koj ua tau raws li qhov xav tau ntawm koj cov neeg siv khoom. "Xav tias koj muaj lub kauj uas nyuaj dhau, lossis nws tsis raug muab faib kom raug, lossis lub vaj huam sib luag yog deformed vim qhov tsis sib xws, nws yuav nyob ntawm seb leej twg hloov cov khoom siv raw rau hauv cov khoom tiav," McLaughland tau hais.
Tej zaum koj yuav xav liam koj lub tshuab rau qhov teeb meem. Tej zaum nws yuav ua rau muaj kev nkag siab, tab sis tsis txhob maj mus txiav txim, ua ntej saib koj tus kheej cov txheej txheem: koj puas tau ua raws li cov chaw tsim khoom cov lus qhia? Lub tshuab puas siv thiab tswj kom raug? Koj puas tau xaiv ib lub kauj uas nyuaj dhau; mos heev; vib nas this; txiav / thim rov qab / tsis raug cai; khaws cia sab nraum zoov; ntub dej; los yog puas?
Koj puas siv lub tshuab sealing ntawm qhov chaw ua haujlwm? Lub ru tsev yuav tsum xyuas kom meej tias lub calibration haum rau txoj haujlwm. "Rau cov neeg kho tshuab, cov vaj huam sib luag kaw, nws yog ib qho tseem ceeb heev los xyuas kom meej tias koj lub tshuab sealing tau ntsuas nrog lub vaj huam sib luag koj tab tom khiav," nws hais.
Tej zaum koj yuav tau hais tias nws yog calibrated, tab sis nws puas yog? McLaughlin tau hais tias "Nrog lub tshuab foob, ntau tus neeg yuav ib qho, qiv ib qho, thiab xauj ib qho," McLaughlin tau hais. teeb meem? "Txhua tus xav ua tus kws kho tsheb." Thaum cov neeg siv pib kho lub tshuab rau lawv tus kheej lub hom phiaj, nws yuav tsis ua raws li cov qauv tsim khoom.
Cov lus qub qub ntawm kev ntsuas ob zaug thiab txiav ib zaug kuj tseem siv tau rau txhua tus uas siv lub tshuab yob txoj kev. Ntev yog qhov tseem ceeb, tab sis qhov dav kuj tseem ceeb. Ib qho yooj yim template gauge los yog steel daim kab xev ntsuas yuav siv tau los xyuas qhov profile loj.
McLaughland tau hais tias "Txhua qhov kev lag luam ua tiav muaj cov txheej txheem," McLaughland tau taw qhia. "Los ntawm qhov kev xav ntawm yob txoj kev, yog tias koj ntsib teeb meem ntawm cov kab ntau lawm, thov nres. Cov khoom uas twb tau ua tiav lawm nyuaj kho… Xav nres thiab hais tias yog, puas muaj teeb meem?”
Mus ntxiv yuav tsuas nkim sijhawm thiab nyiaj txiag ntau dua. Nws siv qhov kev sib piv no: "Lub sijhawm koj txiav 2 × 4, feem ntau koj tsis tuaj yeem coj lawv rov qab mus rau lub vaj ntoo." [Dab Neeg Magazine]
