American Welding Society tau tsim los raws li American National Standards Institute cov cai thiab cov tseev kom muaj, vim tias kev tsim cov khoom lag luam tau dhau los ua cov txuj ci thiab txuj ci zoo heev. Yog li ntawd, tus kws tshaj lij uas tau lees paub yuav tsum yog tus kws tshaj lij kev lag luam hlau, raws li pom los ntawm kev ua tau raws li qhov xav tau yam tsawg kawg nkaus thiab kev paub ntawm tus kws paub txuj ci. Phau ntawv qhia no yuav npog qee cov kauj ruam yooj yim kom ua tiav qhov kev xeem vuam pov thawj.
Cov kauj ruam
Ntu 1 ntawm 2: Npaj rau Kev Xeem
Kauj Ruam 1. Txiav txim siab qhov vuam pov thawj siv rau txoj haujlwm uas koj xav ua
Hauv Asmeskas, muaj ntau txoj cai lij choj tseem hwv thiab xeev thiab kev tswj hwm, thiab tswj hwm lub koom haum uas tswj hwm thiab xav tau qee yam kev tsim vaj tsev, cov cai, thiab cov txheej txheem tsim khoom siv vuam.
Kauj Ruam 2. Kawm 6 yam loj vuam pawg koj yuav raug sim rau
Txawm hais tias, muaj ntau qhov sib txawv ntawm cov txheej txheem hlau tsim thiab txheej txheem, AWS daim ntawv pov thawj xeem feem ntau suav nrog:
- Shielded Metal Arc Vuam - SMAW.
- Gas Metal Arc Welding - GMAW.
- Flux Cored Arc Vuam - FCAW.
- Gas Tungsten Arc Vuam - GTAW.
- Oxy-fuel Gas Txiav thiab;
- Plasma Arc Txiav.
Kauj Ruam 3. Kawm thiab ua raws txhua qhov A. W. S
(American Welding Society) cov qauv (cov lej, cov lus qhia tshwj xeeb, cov lus pom zoo, cov txheej txheem, cov lus qhia, thiab lwm yam).
Feem ntau hom kev tsim cov hlau yuav poob hauv ib qho ntawm ntau yam AWS cov lej hauv Asmeskas.
- ASME - Cov cai no suav nrog ntau yam sib txawv ntawm cov hlau tsim raws li AWS ua, tab sis hauv Asmeskas nws tau siv feem ntau rau kev tsim cov hlab ntsha siab thiab cov kav dej siab.
- API - Txoj cai no suav nrog kev tsim cov tso tsheb hlau luam uas tsis tshua muaj siab thiab kav dej rau thauj thiab khaws cov roj thiab cov roj nyoos.
Kauj Ruam 4. Nrhiav daim ntawv theej tshiab ntawm daim phaj xeem daim phiaj
Xyaum ua txhua yam kev siv vuam (txheej txheem, hlau, tuab) thiab txhua qhov chaw ntawm lub cev, tshem thaj chaw ua haujlwm, thiab huab cua uas koj tuaj yeem sim rau.
- Cov phaj hlau ib txwm kuaj rau AWS D1.1 code muaj ob daim hlau nrog rau 45 degree suav nrog lub kaum sab xis (22.5 degree bevel ntawm txhua lub phaj).
- Cov bevels tau muab tso rau ib leeg, tawm 1/4 "qhov sib txawv ntawm cov plaub hau.
- Ib daim ntawv thim rov qab yog khi rau sab nraub qaum ntawm ob daim hlau txhawm rau tuav lawv ua ke thaum qhov kev ua tiav tiav.
Kauj Ruam 5. Tswv vuam ob txoj haujlwm nyuaj tshaj plaws thiab cov phaj tuab tshaj plaws ntawm qhov kev xeem
Hauv kev xeem D1.1, koj feem ntau yuav ua tiav ob txoj haujlwm: ntsug nce thiab nqis ua haujlwm.
Yog tias koj dhau ob qho kev ntsuas no koj yuav tsim nyog hauv txhua txoj haujlwm thiab yog tias koj ua tiav qhov kev sim siv 1 "tuab phaj koj yuav tsim nyog los ntawm 1/8" mus rau qhov tuab tuab
Kauj Ruam 6. Xyaum ua tib zoo kom txog thaum txhua qhov txuas tsis muaj qhov tsis sib xws thiab tsis tu ncua
Feem ntau qhov ua tsis tiav yog pom ntawm kev kuaj pom thawj zaug.
Thaum txoj cai tso cai rau kev tsis sib xws xws li kev txiav, kev ntxeem tau thiab lwm yam teeb meem, cov no yog cov lus qhia uas tus kws tshuaj ntsuam xyuas yuav siv los nkag siab txog qib txuj ci ntawm tus kws txuas, yog li xyaum ua kom txog thaum koj cov welds zoo li zoo raws li koj tuaj yeem ua tau. Txoj hauv kev no thaum koj ua qhov kev xeem tiag tiag koj yuav tau nyuab dua ntawm koj tus kheej ces lwm tus yuav yog
Kauj Ruam 7. Caw tshaj koj cov phooj ywg tseem ceeb tshaj plaws thiab ua kom tiav rau nitpick koj txoj haujlwm
Tsis txhob cia siab rau koj cov phooj ywg txhawb nqa; lawv tsuas yog muab kev zam txim rau koj es tsis txhob pab koj kom zoo dua qub.
Kauj Ruam 8. Tsis txhob khom rau qhov chaw zoo zoo
Lub qhov txhab tsis zoo tuaj yeem ua daim npog ntsej muag kom zoo. Yog tias koj lub weld hla kev tshuaj xyuas qhov muag, tom qab ntawd cov kauj ruam tom ntej yog ua qhov kev ntsuas puas tsuaj, txwv tsis pub hu ua kev xeem khoov.
- Yog tias lub phaj koj welded tau tuab dua li 3/8 "tom qab ntawv cov ntawv xeem yuav yog 3/8" ib txoj kab txiav los ntawm hla qhov txuas thiab yuav khoov rau sab nrog qhov taw tes ntawm qhov siab tshaj plaws qhov chaw txuas.
- Yog tias lub phaj tsawg dua 3/8 "tuab ces ob daim kab xev yuav raug txiav los ntawm txhua lub phaj thiab cov no yuav khoov nrog ib lub phaj ntsej muag tawm thiab lwm lub hauv paus tawm kom ncab txhua sab.
- Yuav tsum tsis muaj kab nrib pleb, kua muag, cuam tshuam los yog lwm yam tsis xws luag.
- Nws yuav tsum khoov ib yam li cov khoom khov yuav khoov.
Ntu 2 ntawm 2: Zam Kev Ua Yeeb Yam Tsis Zoo
Kauj Ruam 1. Tsis txhob mus nrawm
Sib piv cov muab tub lim hlau noj, qhov tob thiab tuab ntawm qhov txuas, thiab siv cov cua sov kom nrawm rau qhov nrawm ntawm koj cov vuam.
Kauj Ruam 2. Zam kev teeb tsa tsis raug ntawm tus kws txuas
Txheeb ob zaug txhua qhov ntsuas koj siv thiab kho txhua qhov chaw kom raug rau daim ntawv thov raug.
Kauj Ruam 3. Tsis txhob khaws cia tsis raug, tuav, thiab siv cov khoom siv vuam thiab khoom siv
Yog tias koj siv 7018 koj yuav tsum khaws cov hluav taws xob hauv lub qhov cub kom tsis txhob ya raws ntawm cov dej ntws.
Kauj Ruam 4. Siv koj lub sijhawm los ntxuav cov tshuaj paug uas seem tom qab txhua qhov dhau mus
Qhov no tshwm sim feem ntau thaum tawm ntawm cov dej ntws tom qab. Tsis yog, daim ntawv hla dhau yuav tsis hlawv nws.
Kauj Ruam 5. Xyuas kom koj ua tiav fusion ntawm ob sab ntawm qhov txuas
Ua kom tiav tag nrho thaj chaw sib koom ua ke. Nws yuav tsum yog kev hloov pauv du ntawm cov hlau txuas hlau thiab cov hlau puag.
Kauj Ruam 6. Ua tib zoo nyeem tag nrho cov lus qhia thiab tshuaj xyuas ob zaug txhua qhov ntsuas ntawm daim phiaj
Siv koj lub sijhawm thiab txiav ib feem ntawm lub sijhawm txawm tias koj tau xyaum ua tib daim qauv txheej txheem ua ntej.
Cov phaj ntsuas kev ntsuas ntsuas tuaj yeem hloov pauv me ntsis yam tsis tau ceeb toom ua ntej
Kauj Ruam 7. Siv kev nkag siab zoo thiab ib txwm ua raws cov txheej txheem kev nyab xeeb raug
Kauj Ruam 8. Txheeb xyuas tag nrho thaj chaw ua haujlwm thiab cov cuab yeej ua tib zoo saib xyuas kev txuas hluav taws xob thiab txhua yam kev nyab xeeb
Kauj Ruam 9. Hnav khaub ncaws ua haujlwm kom haum uas tiv thaiv koj lub cev tag nrho los ntawm cov hlau yaj, ua kom sov sov, tawg, thiab hluav taws xob poob
- Tsis txhob siv hnab ntim khoom lossis xoob xoob. Koj tab tom ua haujlwm nyob rau ib puag ncig muaj kev phom sij nrog kev txav cov tshuab thiab cov cuab yeej siv fais fab uas koj tuaj yeem raug tshem tawm lossis hlawv tau yooj yim.
- Tsis txhob hnav ris, tsho loj, ntaub thaiv npog lossis npog npog nrog lub hnab ris, lub tes tsho, lossis dab tshos. Koj tuaj yeem raug mob hnyav yog tias qib 2000 degree cov khoom siv hlau yaj los yog lub txim taws raug ntes hauv koj cov khaub ncaws.
- Koj yuav raug sim ntawm cov txheej txheem kev nyab xeeb thiab chaw ua haujlwm huv si ib yam.
Kauj Ruam 10. Ntxuav thiab muab txhua yam ntaub ntawv thiab khoom siv tso rau ntawm lawv qhov chaw khaws khoom kom zoo ua ntej nthuav qhia koj txoj haujlwm rau kev tshuaj xyuas
Kauj Ruam 11. Hmoov Zoo
Lub tswv yim
- Xyaum ua ntu zus thiab ua tib zoo saib rau qhov ua yuam kev ntau thiab koj yuav muaj txoj hauv kev zoo dua.
- Nco ntsoov tias nrog kev ua siab ntev txaus qhov txuj ci zoo li lwm yam tuaj yeem ua tau zoo.
Lus ceeb toom
- Tsis txhob txhuam yam tsis siv lub iav kev nyab xeeb zoo thiab kawm ib chav lossis muaj ib tus neeg qhia koj li cas.
- Qhov no tsis yog kev nyab xeeb. Nws tau kwv yees tias koj paub cov kev ceev faj yuav tsum ua. Yog tias tsis yog li ntawd qhia koj tus kheej thiab nco ntsoov, lub ntiaj teb tsis ua npuas ncauj. Ntau yam khoom yuav ua mob lossis tua koj. Nws nyob ntawm koj kom muaj sia nyob.
