Nws yog kev sib txhuam do vuam!
Cia peb sib paub hnub no!
Kev sib txhuam txhuam vuam tshuab tau tsim los ntawm British Welding Institute (TWI) hauv xyoo 1991. Nws tau thov rau kev tsim khoom patent hauv UK xyoo tom ntej thiab kuj tau thov rau kev tiv thaiv patent hauv ntau lub teb chaws thoob ntiaj teb. Txij li thaum patent tiv thaiv thiab nthuav tawm, kev sib txhuam do vuam tshuab tau nce dav siv ua ntej thiab feem ntau nyob rau hauv lub teeb hlau qauv xws li txhuas alloys thiab magnesium alloys. Nws kuj tau ua tiav qee qhov kev txhim kho hauv thaj chaw ntawm cov khoom siv high-melting point.
Ntxiv nrog rau qhov zoo ntawm kev sib txhuam vuam tshuab, kev sib txhuam txhuam vuam tuaj yeem txuas nrog ntau hom kev sib koom ua ke thiab sib txawv vuam txoj haujlwm. Norway tau tsim lub ntiaj teb thawj kev lag luam kev sib txhuam txhuam cov cuab yeej siv vuam, uas tuaj yeem vuam aluminium nkoj daim hlau nrog lub thickness ntawm 3-15 hli thiab qhov loj ntawm 6 × 16; Xyoo 1998, Lub Chaw Haujlwm Saib Xyuas Chaw thiab Tiv Thaiv ntawm Boeing Lub Tuam Txhab hauv Tebchaws Meskas tau qhia txog kev sib txhuam do vuam tshuab, siv nws yog siv los vuam qee yam foob pob hluav taws; McDonnell Douglas kuj tseem siv cov thev naus laus zis no los tsim cov twj tso kua mis rau nws lub tsheb Delta.
Kev sib txhuam do vuam txoj kev yog tib yam li cov pa sib txhuam vuam. Kev sib txhuam do vuam kuj siv kev sib txhuam kub thiab yas deformation tshav kub raws li vuam qhov chaw kub. Qhov txawv yog tias nyob rau hauv kev sib txhuam do vuam txheej txheem, ib lub tog raj kheej los yog lwm yam zoo li tus nplawm koob (xws li ib tug threaded lub tog raj kheej) yog muab tso rau hauv lub sib koom tes ntawm lub workpiece, thiab lub high-ceev kev sib hloov ntawm lub vuam taub hau ua rau nws mus rub tawm ntawm lub workpiece. vuam workpiece khoom. Yog li ntawd, qhov kub ntawm cov khoom ntawm qhov sib koom ua ke nce thiab softens. Nyob rau tib lub sijhawm, kev sib txhuam txhuam kev sib txhuam yog siv rau cov khoom siv kom tiav qhov vuam. Cov txheej txheem vuam yog qhia nyob rau hauv daim duab "Friction do welding diagram". Thaum lub sij hawm vuam txheej txheem, lub workpiece yuav tsum nruj nreem tsau rau ntawm lub nraub qaum ncoo, ntug ntawm lub vuam taub hau tig ntawm ib tug ceev ceev, thiab seam raws ntug ntawm lub workpiece txav mus rau lub workpiece. Lub protruding seem ntawm lub vuam taub hau txuas mus rau hauv cov khoom rau kev sib txhuam thiab nplawm. Lub xub pwg ntawm lub vuam taub hau rub tawm ntawm qhov chaw ntawm lub workpiece los tsim kom muaj cua sov thiab siv los tiv thaiv cov khoom yas los ntawm kev ntws, thiab tib lub sijhawm, nws tuaj yeem tshem tawm cov oxide zaj duab xis.
Thaum lub sij hawm welding txheej txheem, lub dov koob txuas mus rau hauv kev sib koom ua ke ntawm lub workpiece thaum tig. Kev sib txhuam kub ntawm lub taub hau tig lub taub hau (feem ntau yog lub xub pwg nyom) thiab cov khoom ua haujlwm ua rau cov khoom nyob rau hauv pem hauv ntej ntawm lub vuam taub hau kom muaj zog yas deformation, thiab tom qab ntawd raws li lub vuam taub hau txav, cov khoom siv plastically deformed maj mam tso tom qab lub taub hau. , tsim kev sib txhuam do welding seam. Kev sib txhuam do welding tsis muaj qhov xav tau siab rau cov khoom siv. Cov kev xav tau yooj yim tshaj plaws yog kev sib hloov ntawm lub taub hau vuam thiab qhov sib txheeb ntawm cov khoom ua haujlwm. Txawm tias lub tshuab milling tuaj yeem ua tau raws li qhov yuav tsum tau ua rau me me tiaj tiaj taub qab vuam. Txawm li cas los xij, qhov rigidity ntawm vuam cov cuab yeej thiab fixtures yog qhov tseem ceeb heev. Lub taub hau sib xyaw feem ntau yog ua los ntawm cov cuab yeej hlau, thiab qhov ntev ntawm lub vuam taub hau feem ntau luv me ntsis tshaj qhov xav tau vuam qhov tob. Nws yuav tsum tau muab sau tseg tias kev sib txhuam do weld xaus nrog ib tug keyhole nyob rau hauv lub davhlau ya nyob twg kawg. Feem ntau, qhov keyhole tuaj yeem raug txiav tawm lossis kaw siv lwm txoj kev vuam. Hauv kev teb rau qhov teeb meem keyhole, lub telescopic mixing lub taub hau tau ua tiav tiav, uas yuav tsis tawm ntawm lub qhov tseem ceeb tom qab vuam.
daim ntawv thov
Tsis tas yuav tsum muaj lwm yam khoom siv vuam siv thaum lub sij hawm vuam, xws li vuam rods, vuam hlau, flux, thiab shielding gases. Qhov tsuas yog noj yog qhov welding stirrer.
Kev sib txhuam do vuam tau ua tiav siv hauv kev sib txuas ntawm cov hlau tsis muaj hlau. Txawm li cas los xij, vim muaj kev txwv ntawm cov yam ntxwv ntawm txoj kev vuam, nws tsuas yog txwv rau cov vuam ntawm cov qauv yooj yim, xws li cov qauv ncaj nraim lossis cov qauv cylindrical, thiab cov khoom ua haujlwm yuav tsum muaj kev txhawb nqa zoo lossis padding. Nyob rau hauv txoj cai, kev sib txhuam do vuam siv tau rau vuam nyob rau hauv ntau txoj hauj lwm, xws li tiaj welding, ntsug welding, nyiaj siv ua haujlwm vuam, thiab downward vuam; Nws tuaj yeem ua tiav ntau hom kev sib txuas, xws li pob qij txha, pob qij txha, thiab ceg tawv, thiab txawm tias cov qauv sib txawv. Kev sib txuas nrog cov ntaub ntawv ntau txheej kuj tuaj yeem ua rau vuam ntawm cov khoom siv hlau sib txawv.
Tsis tas li ntawd, kev sib txhuam do vuam, raws li cov txheej txheem vuam txheej txheem, ua rau muaj kev ua qias tuaj me me ua ntej thiab thaum vuam. Lub workpiece tsis xav tau kev tu kom nruj thiab kev npaj ua ntej vuam. Kev sib txhuam thiab nplawm thaum lub vuam txheej txheem tuaj yeem tshem tawm cov oxide zaj duab xis ntawm qhov chaw vuam, thiab tsis muaj pa taws lossis tawg thaum lub vuam txheej txheem. Tib lub sijhawm, lub suab nrov qis. Txij li kev sib txhuam do vuam tsuas yog tso siab rau kev sib hloov thiab txav ntawm lub taub hau vuam kom maj mam vuam tag nrho cov vuam, nws yog ntau zog-txuag dua fusion vuam los yog cov pa sib txhuam vuam.
Txij li thaum lub tshav kub input nyob rau hauv kev sib txhuam do welding yog me dua li ntawm fusion vuam, tsis muaj melting ntawm hlau ntawm qhov sib koom ua ke. Nws yog cov txheej txheem vuam-state uas tswj cov khoom siv hlau ntawm lub hauv paus hlau hauv cov hlau thiab tuaj yeem vuam hlau matrix cov ntaub ntawv sib xyaw thiab sai sai. Cov ntaub ntawv uas yuav ua rau muaj kev phiv thaum siv rau fusion vuam.
Cov ntawv thov kev lag luam tseem ceeb suav nrog aerospace, kev lag luam tiv thaiv, kev tsim nkoj, kev tsheb ciav hlau thiab kev loj, kev tsim tsheb, thiab kev lag luam hluav taws xob.
