Nyob rau hauv cov yeeb nkab vuam, txoj haujlwm txhais los ntawm cov yeeb nkab kev qhia thiab cov kev taw qhia ntawm Weld, nrog cov qauv teem los ntawm cov koom haum zoo li Asmeskas Vuam Society (AWS). Cov haujlwm no tus account rau cov yeeb nkab cov cylindrical, uas yuav tsum tau muab txoj hauv kev nkhaus, qhov twg welds ncaj. MuajTsib Thawj Cov Hluav Taws Xob Hluav Taws Xob, txhua tus neeg sib koom ua ke los ntawm "G" (rau Groove Welds, feem ntau ntawm cov yeeb nkab ua haujlwm) thiab tus lej uas qhia txog cov yeeb nkab lub kaum qhov sib txheeb ze rau hauv av. Txhua txoj haujlwm kev xeem sib txawv kev txawj ntse, los ntawm cov kav dej yooj yim rau cov koom tes ua ke.
{{0 {0} g txoj hauj lwm (kab rov tav dov yeeb)
Qhov chaw 1g yog qhov yoojyim tshaj plaws ua hluav taws xob vuam txoj hauj lwm, qhov twg cov yeeb nkab dag kab rov tav thiab tuaj yeem tig raws li koj weld.
Yeeb Nkab Taw: Cov yeeb nkab tau muab tso rau cov chais lossis sawv ntsug, ua tib zoo rau hauv av. Raws li koj weld nyob ib ncig ntawm cov yeeb nkab nruab nrab, koj tuaj yeem yob nws, ua kom lub weld sib koom ua ke ib txwm nyob hauv txoj haujlwm tiaj tus.
Weld taw: Weld raws li cov yeeb nkab nkhaus, tab sis dov cov yeeb nkab txhais tau tias koj yeej tseem ceeb vuam "
Qhov tseem ceeb nkauj: Qhov zoo tagnrho rau cov neeg pib tshiab, vim tias nws tsawg kawg kev sib tw ntawm lub ntiajteb txawj nqus. Nws tau siv rau qhov tsis - cov kav dej tseem ceeb lossis thaum dov tau (piv txwv, cov ntaub qhwv ntaub qhwv nrog cov yeeb nkab nrog chais).
Cov Ntawv Thov: Cov kav dej hauv cov chaw tsim khoom, qhov twg cov yeeb nkab tuaj yeem tig tau thaum lub sijhawm vuam los tswj txoj kev weld tiaj.
{2. 2 g txoj hauj lwm (ntsug dawb yeeb nkab)
Qhov chaw 2G muaj feem cuam tshuam nrog cov yeeb nkab dawb huv, qhov chaw uas tus weld tau ua rau kab rov qab nyob ib ncig ntawm nws txoj kev ncig.
Yeeb Nkab Taw: Cov yeeb nkab sawv ncaj ncaj (ntsug), tsau nyob rau hauv qhov chaw yog li nws tsis tuaj yeem tig. Weld sib koom tes sau kab rov tav nyob ib ncig ntawm cov yeeb nkab "lub duav."
Weld taw: Cov Weld ua raws kab rov tav, ncig ib ncig ntawm cov yeeb nkab ntsug. Lub ntiajteb txawj nqus rub tawm cov hlau hauv qab, yog li koj yuav tsum ua lub teeb ci sab nraud (15-30 degree) kom tiv thaiv sagging.
Kev sib tw tseem ceeb: Tswj txawm fusion nyob ib ncig ntawm txoj kev nkhaus, tshwj xeeb yog nyob rau hauv "hauv qab" ntawm Weld (6 teev txoj haujlwm), qhov twg nqus tau muaj zog tshaj.
Cov Ntawv Thov: Ntsug cov kav dej ntsug hauv cov tuam tsev (piv txwv li, cov pa tso pa tawm, lossis cov yeeb nkab uas tsis tuaj yeem tig tau ib zaug ntsia.
{{0 {0} g txoj hauj lwm (kab rov tav tas li yeeb nkab)
Qhov 5G txoj hauj lwm yog rau kab rov tav ruaj khov yeeb nkab, qhov twg weld khiav ntsug ncig nws qhov kev ua haujlwm tseem ceeb tshaj plaws rau cov yeeb nkab tseem ceeb tshaj plaws.
Yeeb Nkab Taw: Cov yeeb nkab lim qab tav toj tab sis yog tsau (tsis tuaj yeem tiv thaiv (yog li Weld sib koom ua ke los ntawm sab saum toj (12 teev) mus rau hauv cov yeeb nkab.
Weld taw: Weld ua raws li txoj kev ntsug, ncig. Koj pib ntawm sab saum toj, txav mus ib sab mus rau hauv qab, ces ua tiav rau lwm sab. Qhov no yuav tsum tau hloov kho kom haum rau lub ntiajteb txawj nqus: nyob rau sab saum toj (tiaj tus (tiaj tiaj (tiaj {2} Zoo li), nqus tau pab; Hauv qab (overhead - zoo li), nqus tau ua haujlwm tawm tsam koj.
Kev sib tw tseem ceeb: Adapting txheej txheem raws li koj txav mus ncig ntawm cov yeeb nkab - nws zoo li (12 teev) mus rau overhead (6 teev) thiab rov qab. Tshav kub thiab taug kev mus ncig yuav tsum hloov pauv kom tiv thaiv cov plawj lossis underfusion.
Cov Ntawv Thov: Cov khoom lag luam feem ntau (piv txwv li, roj thiab roj av, cov hlab ntsha siab) uas tau muab cov khoom siv horizontally thiab tsis tuaj yeem hloov tav toj ntawm vuam.
{{04. 6 g txoj hauj lwm (45℃inclined tsau yeeb nkab)
Qhov 6g txoj hauj lwm yog qhov yeeb nkab tshaj plaws: cov yeeb nkab tsau ntawm 45 lub kaum sab xis, uas weld sib xyaw txhua txoj haujlwm hauv ib txoj haujlwm yav dhau los hauv ib txoj haujlwm dhau los hauv ib qho kev nkhaus mus txuas ntxiv.
Yeeb Nkab Taw: Cov yeeb nkab yog tilted 45℃ntawm kab rov tav, tsau rau hauv qhov chaw. Lub weld sib koom ua raws li kab pheeb ces kaum, raws li txoj kev ncig ntawm cov yeeb nkab.
Weld taw: Raws li koj weld ncig ntawm cov yeeb nkab, koj dhau los ntawm flag - Zoo li, kab rov tav, thiab siv nyiaj rau hauv ib qho hauv ib qho kev txav suab. Qhov kev sim no paub Mastery ntawm txhua txoj kev sib tsoo.
Kev sib tw tseem ceeb: Tas li kev kho lub teeb lub tsev, cua sov, thiab taug kev nrawm dua kom haum rau cov tub rog sib tsoo. Nws feem ntau siv los ua kev pov thawj kev kuaj mob rau cov neeg muab tshuaj tua kab mob.
Cov Ntawv Thov: Tseem Ceeb, Angled Yeeb Nkab Sib Koom Tes (piv txwv li, Offshore Roj Rigs, Refinore Rigs, Qhov Kev Ntsuas Nruab Nrab, Puas muaj ib qho tsis haum thiab Welds Tso Dawb.
6gr txoj hauj lwm (45℃incined yeeb nkab nrog lub nplhaib txwv)
Lub 6gr txoj hauj lwm yog qhov sib txawv ntawm 6G, ntxiv lub nplhaib "txwv tsis pub" - Tus hlau dab tsi nkag mus rau Weld sib koom tes.
Qhov tseem ceeb nkauj: Lub nplhaib simulates cov chaw nruj (piv txwv li, kav dej nyob rau hauv cov tshuab uas muaj neeg coob), yuam cov welder los ua haujlwm nrog tsawg tub txav. Nws yog qhov ntsuas qhov kawg ntawm qhov ntsuas thiab hloov tau.
Kev siv: Tshwj tseg rau cov ntawv pov thawj tshwj xeeb, kom tau cov welders tuaj yeem ua haujlwm tau nyob hauv cov chaw muaj kev muaj kev nyab xeeb.
Vim li cas cov haujlwm no teeb meem rau cov yeeb nkab vuam
Cov hluav taws xob vuam cov chaw yog qhov tseem ceeb vim tias cov kav dej feem ntau nqa cov kua dej (roj, dej) lossis ua haujlwm nyob rau hauv siab-} ntawv pov thawj thiab muaj pov thawj. Txoj hauj lwm sau cov txheej txheem: Rolling kav dej (1g) yog ib qho yooj yim, tab sis cov kav dej yooj yim, tab sis cov kav dej ruaj khov (2G, 5g, 6g) yuav tsum muaj kev txawj rau kev txawj los tiv thaiv kev sib tsoo. Cov ntawv pov thawj nyob rau hauv 5G thiab 6g feem ntau yuav tsum tau rau cov yeeb nkab ua haujlwm, raws li lawv ua pov thawj ib qho chaw muag khoom tuaj yeem ua qhov tseeb- ntiaj teb cov xwm txheej.
Hauv ntej, muajTsib Thawj Cov Hluav Taws Xob Hluav Taws Xob: 1g (yob tawm), 2G (ntsug ruaj khov), 5g (45℃inclined), thiab 65℃inclined nrog lub nplhaib txwv). Txhua txoj kev tsim ntawm lub xeem, nrog 6g / 6gr uas sawv cev qib siab tshaj plaws ntawm kev txawj ntse.
