Hauv kev lag luam thiab kev tsim kho kev lag luam, vuam cov khoom siv hlau feem ntau yog siv. Qee zaum koj ua tsis tau yam tsis muaj nws. Cov txheej txheem yog complex thiab siv zog heev. Qee zaum, nws yog fillet vuam vuam uas yuav tsum tau siv los ua kev sib txuas. Hom kev sib txuas no yog suav tias yog ib qho ntawm feem txhim khu kev qha thiab ruaj khov. Txawm li cas los xij, nws tsis tuaj yeem ua lub kaum vuam yam tsis muaj kev paub tshwj xeeb, vim tias nyob rau hauv cov txheej txheem ntawm kev ua hauj lwm koj yuav tsum coj mus rau hauv tus account ntau me me nuances.
vuam nta
Lub kaum sab xis yog qhov ntau heev. Nrog nws, koj tuaj yeem txuas ob lub phaj hlau lossis cov kav dej profile. Qhov tseem ceeb tshaj plaws yog qhov kev ncua deb ntawm ob cov khoom no yuav tsum tsis pub tshaj 180 degrees.
Qee zaum, nws yuav tsum tau txuas ntau yam khoom rau hauv ib lub qauv hlau loj, qhov twg cov pob qij txha yuav muaj lub kaum sab xis ntawm 90 degrees. Tag nrho cov no yog qhov tsim nyog txhawm rau txhawm rau txhawm rau txhawm rau txhim khu kev qha, ruaj khov thiab muaj peev xwm tiv taus cov khoom hnyav.
Fillet welds muaj ntau heev, tshwj xeeb tshaj yog thaum koj xav tau los tsim cov qauv loj thiab muaj zog. Feem ntau lawv muaj cov ces kaum uas yuav tsum tau ua tib zoo ua thiab txuas nrog. Ntau lwm cov tswv yim siv tau los ua qhov no, tab sis vuam yog txoj kev txhim khu kev qha tshaj plaws los txuas ob cov khoom hlau.
Cov kev cai tshwj xeeb yog tsim rau hom haujlwm no, vim tias lub zog ntawm tag nrho cov qauv nyob ntawm qhov zoo ntawm cov seam. Hom kev sib txuas no yog suav tias yog ib qho. Nws tuaj yeem nqa tau siv cov cuab yeej siv roj, lossis lwm yam, kev teeb tsa niaj hnub ntau dua. Qhov tseem ceeb tshaj plaws yog ua raws li cov cuab yeej technology.
Ntau yam seams
Corner weld muab faib ua hom hauv qab no:
- lapped;
- thaum ntawm kev sib tshuam cov npoo ntawm cov khoom yog nruj nreem nyob ib sab;
- ib ntug ntawm cov khoom siv rau ib qho chaw tiaj tus ntawm lwm tus (tee seam);
Tsis zoo li cov khoom siv sib txuas, nws nyuaj dua los ua kom zoo nkauj thiab muaj zog fillet welds. Kev ua haujlwm yog qhov nyuaj ntxiv los ntawm qhov tseeb tias vuam yuav tsum tau ua nyob rau hauv ntau txoj haujlwm. Txawm tias tus kws tshaj lij welder tuaj yeem muaj teeb meem ntawm kev ua haujlwm, piv txwv li, yog tias koj xav tau ua ib qho tee seam ntawm cov khoom uas tseem tig rov qab. Tsis tas li ntawd, lub kaum sab xis tuaj yeem cuam tshuam los yog txuas ntxiv, luv lossis ntev. Lub seam luv tsis pub tshaj 2.5 centimeters, thiab ib tug ntev - 10 centimeters.
nyuaj thaum vuam
Kom tus tswv ua taukom ua tiav qhov zoo tshaj plaws thiab zoo seam, koj yuav tsum paub txog qhov tsis xws luag uas yuav tshwm sim thaum ua seam. Feem ntau, cov fillet pob tw weld yog unreliable vim lub fact tias cov ntaub ntawv weld nyob unevenly. Nyob rau hauv qhov kev txiav txim ntawm kub kub, cov hlau melts thiab rushes cia. Yog li ntawd, sab saum toj ntug tsis tuaj yeem koom nrog kev sib koom ua ke. Tsis ntev los sis tom qab ntawd, nyob rau hauv kev cuam tshuam ntawm kev thauj khoom loj, tus qauv yuav poob sib nrug.
teeb meem tseem ceeb
Lub kaum sab xis tsis ncaj ncees tuaj yeem ua rau lub voj voos ntsug. Ob yam khoom uas yuav tsum tau txuas nrog xws li ib tug seam yog tsis tshua muaj arbitrary zoo. Nyob rau hauv cov ntaub ntawv no, nws yog ib qho tseem ceeb heev kom raug xam cov fillet weld. Cov khoom yuav tsum nyob rau hauv qhov tseeb. Feem ntau lawv muaj qhov tsis sib xws (ntev, dav thiab tuab).
txhawm rau ua tiav cov haujlwm zoo, nws yuav tsum ua tib zoo ua tib zoo xaiv qhov ntsuas qhov ntsuas hluav taws xob. Yog tias qhov tam sim no tsis muaj zog heev, qhov no yuav ua rau ob txhais ceg convex. Qhov no txhais tau tias cov khoom siv hauv paus yuav tsis yaj zoo. Hloov pauv, yog tias qhov tam sim no khaus heev, txhais ceg yuav ua rau lub ntsej muag concave. Ob sab ntawm cov khoom hlau yuav muaj kev nkag mus tob heev. Raws li qhov tshwm sim, tus qauv tsim tseem yuav tsis zoo.
Npaj ua haujlwm
Yuav ua tau txoj haujlwm zoo tshaj plaws, nws tsis txaus kom muaj cov khoom siv zoo, paub txog qhov tsis xws luag thiab ua raws li cov cai kev nyab xeeb. Ua ntej tus tswv mus ua hauj lwm, nws yuav tsum tau npaj cov sab ntawm cov vuam zoo.
Basic rules
Yog xav tau kev sib txuaslwm daim hlau, lub thickness uas tsis pub tshaj 5 hli, ces tsis muaj kev npaj tshwj xeeb yuav tsum tau. Yog hais tias xeb muaj nyob rau ntawm cov khoom, nws yuav tsum tau muab tshem tawm nrog ib tug tshwj xeeb txhuam.
Tsuas yog tom qab ntawd koj tuaj yeem kos, kho cov khoom kom zoo thiab pib vuam. Tib yam siv tau yog tias nws yuav tsum tau nqa tawm ib qho fillet overlap weld. Txhawm rau kom cov qauv ua kom muaj zog txaus thaum kawg, nws yog ib qho tsim nyog yuav tsum tau siv ob txoj hlua khi ntawm txhua sab ntawm ib qho.
Kev ua haujlwm yuav nyuaj dua yog tias koj xav tau ua haujlwm nrog cov hlau, lub thickness ntawm ntau tshaj 5 hli. Nyob rau hauv cov ntaub ntawv no, tus tswv yuav tsum ua ib tug me me bevel ntawm 45 degrees ntawm daim ntawv txuas. Qhov no yuav tsim ib qho chaw me me uas cov hlau molten yuav ntws. Yog li ntawd, lub kaum sab xis yuav tig tawm kom ruaj thiab txhim khu kev qha. Thaum tus tswv ua haujlwm nrog cov hlau nrog lub thickness ntau dua 1 cm, nws yuav tsum tau txiav cov npoo ntawm ob sab. Cov tshuab no pab tiv thaiv cov seam los ntawm kev kub hnyiab.
Tom qab cov npoo tau npaj thiab cov khoom tau ruaj khov, tus kws tshaj lij yuav tsum tsis txhob hnov qab txog kev teeb tsa tacks ntawm ob sab. Qhov no yog qhov tsim nyog kom cov seam tsis warp thaum lub sij hawm vuam, thiab cov khoom hlau tsis deform.
Ua kom cov qauv muaj zog thiab raug raws li qhov ua tau, vuam tsis yog ib txhij ntawm ob sab, tab sis hloov pauv. Nws yog ib qho tseem ceeb kom ua tiav cov hauj lwm ntawm ib sab, thiab tom qab ntawd txav mus rau lwm qhov. Yog tias koj tsis ua raws li txoj cai no, potholdersyuav tsis muaj peev xwm tiv taus lub load thiab feem ntau yuav tawg.
Field welding method
Lub sijhawm ua haujlwm no, qhov tshwm sim ntawm qhov tsis xws luag yog siab heev. Cov neeg ua haujlwm tshaj lij siv ntau cov txheej txheem yooj yim, ua tsaug uas koj tuaj yeem tau txais cov seam zoo tshaj plaws. Txhawm rau kom nkag siab yuav ua li cas vuam fillet weld kom raug thiab siv cov txheej txheem dab tsi, koj yuav tsum tau xyuam xim rau qhov xwm txheej dav dav thiab xaiv qhov kev xaiv vuam yooj yim tshaj plaws.
Nkoj txoj kev
Txoj kev no yog qhov tsim nyog rau kev vuam yog tias tus tswv ua haujlwm nrog cov qauv me me uas nyob rau saum npoo, tab sis tsis kho rau nws. Lawv tuaj yeem hloov tau. Cov txheej txheem no tsuas yog siv los ntawm cov pib tshiab. Nyob rau hauv cov ntaub ntawv no, cov khoom yog ntsia nyob rau hauv cov duab ntawm tsab ntawv V. Tus tsim yog me ntsis reminiscent ntawm lub nkoj, li no lub npe ntawm cov txheej txheem.
Tus tswv yuav tsum tuav lub electrode vertically, me ntsis tilting nws ntawm nws tus kheej. Hauv qhov no, thaum lub sijhawm ua haujlwm, kev txav oscillatory tsis tuaj yeem ua. Lub sijhawm ua haujlwm ntawm kev ua haujlwm yog nyob ntawm qhov tuab ntawm cov hlau. Qee lub sij hawm nws yuav siv sij hawm ntau dhau los ua kom muaj zog heev thiab txawm tias seam.
Yuav kom muab lub seam qhov dav xav tau, yav tom ntej, tus tswv tuaj yeem ua qhov kev sib hloov vuam. Ua tsaug rau txoj kev no, tus kws kho mob tshwj xeeb muaj peev xwm siv cov khoom muab tub lim ib txhij ntawm ob sab. Qhov no pab kom tsis txhob muaj qhov tsis xws luag, cov pob qij txha tsis zoo.
Txoj haujlwm
Nyob zootej nkoj nquam mus quav cov qauv loj los ntawm ib tug kws tshwj xeeb yuav tsis ua hauj lwm, yog li koj yuav tsum tau welding nyob rau hauv qis txoj hauj lwm. Tus tswv yuav tsum me ntsis qaij lub electrode thiab ua haujlwm ntawm lub kaum sab xis ntawm 45 degrees. Hauv qhov no, koj yuav tsum txav mus rau sab laug thiab sab xis. Qhov no yog qhov tsim nyog thiaj li ua kom tiav cov seam.
Thaum tus tswv nyuam qhuav pib vuam, tsis tas yuav ua kom hloov pauv. Nyob rau hauv thawj theem, nws yog ib qho tseem ceeb rau qualitatively txuas cov hlau ntsiab. Cov kws tshaj lij pom zoo kom ua me me thaum ua haujlwm. Qhov no yog tsim nyog nyob rau hauv thiaj li yuav me ntsis tsav deb lub slag ntws mus rau lub seam. Yog tias tus tswv tsis ua qhov no, ces lub slag tuaj yeem thaiv qhov pom ntawm qhov chaw ua haujlwm. Yog hais tias lub ntsiab suture tau ua kom raug, khov kho thiab tsis muaj qhov tsis xws luag, ces cov sutures hauv qab no tuaj yeem siv tau.
Txawm tias cov haujlwm tau ua tiav los ntawm tus tswv zoo, qee zaum qhov vuam, uas tau ua ntawm lub kaum sab xis, yuav muaj qhov tsis zoo thiab tsis zoo. Qhov no yog vim qhov kev sib txuas feem ntau tsis sib xws. Lawv yog me ntsis convex saum lub ntsiab nto. Tsis tas li ntawd, tej zaum yuav muaj slag residues, me me thiab hlau hais rau ntawm seam.
Txoj kev stripping
Yuav kom cov khoom tiav kom zoo nkauj, koj yuav tsum tshem tawm tag nrho cov no. Cov txheej txheem no hu ua kev ntxuav. Tus kws kho mob tshwj xeeb yuav tsum ua ntau theem. Ua ntej, nrog kev pab los ntawm ib tug skein los yog ib tug chisel, nws knocks down scales, thiab ces nrog ib tug grinder nws theem saum npoo ntawm seam. Yog tus tswv tseem tsis tuaj yeem ua tus seam txawm,koj tuaj yeem kho qhov no los ntawm kev siv cov tin molten rau saum npoo.
