Nyob rau hauv tig (tungsten inert roj) vuam, ib tug pasader, tab sis nws yog qhov tseem ceeb rau cov haujlwm feem ntau. Txawm hais tias koj xav tau ib qho nyob ntawm hom weld, cov tuab ntawm cov hlau, thiab lub zog uas yuav tsum tau ua ntawm cov sib koom ua ke. Cia peb tawg thaum tus pas nrig ua tus tsim nyog, thaum nws tsis yog, thiab vim li cas nws tseem ceeb rau weld zoo.
Thaum kojxav tauIb tug muab tub lim rau Tig Vuam
Tus pas nrig ua haujlwm yog qhov tseem ceeb hauv feem ntau Tig vuam scenarios, raws li nws muab cov khoom siv uas xav tau los tsim cov pob qij txha muaj zog, txhim khu kev qha ntawv txhim khu kev qha. Nov yog cov xwm txheej tseem ceeb uas tsis yog - sib tham:
1. Koom nrog ob daim hlau
Thaum vuam ob daim nyias nyias (piv txwv li, pob tw pob qij txha, t- pob qij txha, lossis ncej puab pob qij txha), ib tus pas nrig sib txuas ua ke txuas ntxiv rau ntawm lawv. Tsis muaj cov tub muab tub rog, ntawm kev sib txuas ntawm cov hlau ib leeg yuav tsis ntws txaus los ua daim ntawv cog lus txuas ntxiv yog tias muaj qhov sib txawv me me (ib txwm muaj nyob rau hauv tiag tiag- ntiaj teb cov phiaj xwm).
Piv txwv li: vuam ob daim hlau aluminium rau hauv lub pob tw pob qij txha. Txawm tias 0.01-nti sib txawv yuav tawm hauv qhov chaw tsis muaj zog uas tsis muaj tub lim. Tus pas nrig zoo li ER4043 melts rau hauv qhov sib txawv, fusing ob daim hlau rau hauv ib qho, sib koom ua ke.
2. Vuam hlau tuab dua li 1/8 nti
Cov hlau tuab (1/8 nti lossis ntau dua) yuav tsum tau muab tus pas nrig ua rau kom paub meej tias lub weld nkag mus tag nrho. Qhov kub ntawm tus arc muaj peev xwm yaj ntawm cov av tuab, tab sis tsis muaj muab tub lim, lub pas dej molten yuav tsis ncav cuag kom muaj zog txaus kom fuse tag nrho cov tuab. Lub pas dej ntxiv ntxiv cov khoom uas nyob ntawm pas dej, ua kom muaj kev sib dhos los ntawm qhov chaw rau lub hauv paus ntawm kev sib koom ua ke.
Piv txwv li: vuam ib ¼ - nti stainless hlau yeeb nkab. Ib tug 308l muab cov nqaj yaj melts rau hauv lub pas dej weld mus txog sab hauv phab ntsa {}}}}}} ceev ntsaws rau hauv cov kav dej los yog kev siv tshuab.
3. Kev kho cov kab nrib pleb, qhov, lossis cov chaw hnav
Tig vuam yog dav siv rau kev kho cov hlau, thiab ib tus pas nrig ua haujlwm tseem ceeb rau kev rov tsim kho cov khoom. Cov kab nrib pleb, qhov, lossis hnav cov npoo tsis tuaj yeem kho tau nrog tsuas yog lub hauv paus hlau {1} Sau rau muab cov ntawv "tshiab"
Piv txwv li: txhim kho ib qho tawg hauv lub ntsej muag hlau lub cav thaiv. Ib npib tsib xee - roated fool loard rau hauv kev tawg, kev sib koom tes nrog cov hlau cam khwb cia thiab tiv thaiv kev puas tsuaj ntxiv. Tsis muaj tub lim, cov kab nrib pleb yuav nyob tsis muaj zog.
4. Vuam Cov Hlau
Thaum koom nrog cov hlau zoo li cov hlau thiab hlau hlau thiab tooj liab thiab tooj liab thiab tooj dag, ib tug pas nrig ua tus tso ua ke ua ke "middleman." Kev sib cais me me feem ntau tsim cov pej xeem brittle thaum melted ua ke, tab sis ib tug pas nrig ua haujlwm tsim rau ob yam khoom zam no.
Piv txwv: vuam ib tug tooj dag fitting mus rau lub tooj liab yeeb. Lub tooj liab {{1} cov nyiaj sau ua ke rau ob leeg sib koom ua ke uas tiv thaiv corrosion.
Thaum kojtsis txhobXav Tau Tus Quav Ua Si Rau Tig Vuam
Ib tug pas nrig ua haujlwm tsis tsim nyog tsuas yog muaj tseeb heev, muaj qee tus neeg sib cav sib ceg rau nws tus kheej uas tsis tau muab tso rau cov tub luam. Nws ua haujlwm nkaus xwb:
1. Cov hlau yog cov tawv nyias nyias (16 ntsuas cua lossis thinner)
Nyias hlau (piv txwv li, 0.06-nti txhuas los yog 0.03-nti hlau) melts yooj yim, thiab yog tias arc muaj peev xwm yaj lawv cov npoo txaus kom fuse lawv tsis muaj muab tub.
Piv txwv: vuam ib daim ntawv txiav nyias rau daim paib zoo nkauj, qhov twg cov npoo tau clamped nruj nrog xoom sib zog. Lub arc melts cov npoo, thiab lawv ntws ua ke los ua qhov tsis muaj zog tab sis ua haujlwm ua haujlwm.
2. Qhov sib koom ua ke yog "fusion -} tsuas yog" tack weld
Tack Welds - Cov me me, cov ntawv vels ib ntus los tuav cov chaw ua ntej thaum kawg welding filler. Cov tacks no tsis yog muaj zog; Lawv tsuas yog khaws cov ntawv ua kom tiav kom txog thaum tus kheej weld (nrog muab tub lim) yog ntxiv.
Piv txwv li: khi ob lub hlau nyias hlau ua ke. Ib qho me me autogenous tack tuav lawv nyob rau hauv txoj hauj lwm, tab sis ib tug carter pas yuav siv rau qhov kawg, thauj {1} {bearing weld.
3. Lub phiaj xwm tsis yog - cov qauv thiab zoo nkauj
Rau cov hniav zoo nkauj uas muaj zog tsis muaj teeb meem (piv txwv li, cov duab puab hlau puab), autogenous vuam yuav txaus. Lub weld yuav tsis muaj zog, tab sis nws zam kev pom cov kab.
Vim li cas tus pas ua haujlwm txhim kho TIG Welds (txawm tias tsis yog "yuav tsum tau")
Txawm tias nyob rau hauv cov ntaub ntawv uas muaj autogenous welding ua hauj lwm, tus pas nrig ua tus muab ua kom muaj txiaj ntsig ntau dua:
Lub zog: Sau cov khoom ntxiv rau cov khoom siv rau Weld, ua kom muaj zog dua li qhov fusion -}}}}}} s sib koom tes. Qhov no yog qhov tseem ceeb rau txhua feem uas ris qhov hnyav lossis kev ntxhov siab.
Kev Zam Txim: Zoo kawg nkaus raws li, qhov sib txawv {- pob qij txha tsis tshua muaj. Ib tug pas nrig ua rau ua cov txiv ntoo me me, kom ua tau raws li Weld tsis poob vim tsis tiav fusion fusion.
Tawg: Cov pas nrig muab rau kom phim cov qauv hauv paus (piv txwv li, ER5356 rau 5000-koob-series Aluminium), txo cov tawg tshwm sim los ntawm cov nqi txias.
Tshuaj Txhim Kho Cov Duab: Tus pas nrig cia koj ua rau Weld Bead (dav, smoother) rau cov tsos zoo dua lossis faib cov kev ntxhov siab kom zoo.

Rau feem ntau Tig vuam cov dej num -, lossis kho cov hlau -Tus pas nrig ua rau tsim nyogCov. Nws ua kom muaj zog, sib txawv {{- pub dawb, thiab ruaj pob qij txha, txawm tias thaum hlau tsis zoo sib xws. Thaum autogenous vuam ua haujlwm rau nyias, tsis - cov hlau, lossis cov kev zam tau zoo, nws yog qhov kev txiav txim siab. Ib tug pas nrig ua rau muaj tus yuam sij rau kev ntseeg siab, siab - Zoo Tig Welds nyob rau hauv txhua cov xwm txheej.
