Muaj ntau txoj kev vuam. Ntawm lawv yog cov txheej txheem txawv xws li kev sib txhuam do vuam. Nws qhov txawv feature yog tsis muaj consumables xws li electrodes, vuam hlau, shielding gases. Ib txoj kev tsim tshiab tau txais kev lees paub thoob plaws.
History of Appearance
Keeb kwm ntawm kev sib txhuam txhuam vuam (FSW) pib xyoo 1991. Nws yog ib qho kev txhim kho tshiab ntawm British Welding Institute (TWI). Ob peb xyoos tom qab, thev naus laus zis tau siv hauv kev tsim dav hlau thiab nkoj.
thawj lub tuam txhab muab cov thev naus laus zis tshiab rau hauv kev tsim khoom yog Norwegian Marine Aluminium thiab American Boeing. Lawv siv cov cuab yeej vuam los ntawm ESAB kev txhawj xeeb, uas tshwj xeeb hauv kev txhim kho hauv kev sib hloov kev sib txhuam vuam (PCT), hauv lawv cov lag luam.
Txij li xyoo 2003, lub tuam txhab tau tshawb fawb tsis tu ncua txog qhov muaj peev xwm ntawm kev sib txhuam do vuam. Piv txwv li, muajCov txheej txheem tau tsim los rau vuam aluminium alloys thiab lawv cov kev hloov kho, uas yog siv rau hauv kev tsim kho ntawm lub dav hlau, nkoj thiab cov thawv railway.
Hauv kev lag luam dav hlau, nws pom tau tias tuaj yeem hloov cov pob qij txha riveted nrog cov welded sawv daws yuav. Ntxiv mus, qhov ceev ntawm vuam los ntawm FSW txoj kev ho ntau tshaj qhov ceev ntawm hluav taws xob arc. A 6m ntev weld tuaj yeem tsim nyob rau hauv ib feeb, thaum cov pa vuam ceev tsuas yog 0.8-2m / min rau ib feem tuab ntawm 0.5cm.
Qhov tseem ceeb ntawm txheej txheem
Hlau sib koom tshwm sim vim cua sov hauv thaj chaw vuam los ntawm txoj kev sib txhuam. Lub ntsiab vuam cuab tam ntawm kev sib txhuam do vuam yog ib tug hlau pas nrig, muaj ob halves: ib tug dab tshos thiab lub xub pwg nyom.
Nrog nws qhov protruding, tus pas nrig rotating yog raus rau hauv cov khoom, ua rau muaj zog cua sov. Nws cov khoom siv yog txwv los ntawm lub xub pwg nyom, tsis pub lub workpiece yuav tsum tau welded kom dhau mus. Hauv thaj chaw cua sov, cov khoom siv tau nce nws cov yas thiab, nias los ntawm lub xub pwg nyom, tsim ib qho loj.
Cov kauj ruam tom ntej yog kev txav ntawm tus pas nrig raws thaj tsam welded. Tsiv mus rau pem hauv ntej, lub xub pwg sib xyaw cov hlau uas muaj cua sov, uas, tom qab txias, ua kom muaj kev sib txuas zoo.
Dab tsi cuam tshuam rau qhov zoo ntawm STP
Kev sib txhuam txhuam vuam yog ib qho kev hloov pauv tas li. Tab sis tam sim no muaj ob peb yam uas cuam tshuam qhov zoo ntawm kev sib txuas:
- Force generated by the tool.
- Tus nqi nojwelding taub hau.
- Tus nqi ntawm lub xub pwg nyom.
- Kev nrawm nrawm ntawm kev sib hloov ntawm tus pas nrig.
- Tilt angle.
- Pub lub zog ntawm tus pas nrig.
Kev tswj cov yam ntxwv ntawm vuam tso cai rau koj kom ua tiav qhov sib txuas ntawm cov hlau sib txawv. Piv txwv li, aluminium thiab lithium. Lithium, vim nws qhov ntom ntom ntom thiab siab zog, tuaj yeem ua raws li kev sib xyaw ua ke ntawm txhuas alloy qhov chaw no kom siv rau hauv kev lag luam hauv aerospace.
Kev sib txhuam txhuam vuam tuaj yeem hloov tau yooj yim forging, stamping, casting, thaum lawv siv los tsim cov khoom los ntawm cov hlau nyuaj. Piv txwv li, steels nrog austenite thiab pearlite qauv, steels ua los ntawm txhuas los yog bronze.
Nyob rau thaj chaw twg siv
Kev lag luam xws li kev lag luam tsheb ua haujlwm tas li yuav ua li cas txhawm rau txhim kho lub zog ntawm cov khoom thaum txo nws qhov hnyav. Nyob rau hauv no hais txog, muaj ib tug tas mus li kev taw qhia ntawm cov ntaub ntawv tshiab uas yav tas los uncharacteristic vim complexity ntawm kev ua. Ntau zuj zus, cov khoom siv xws li subframes thiab qee zaum tag nrho lub cev yog tsim los ntawm txhuas los yog ua ke ntawm txhuas.
Yog li, hauv 2012, Honda tau siv cov khoom siv ntxiv thiab kev sib txhuam txhuam vuam los tsim subframes rau nws cov tsheb. Lawv qhia txog kev sib xyaw ntawm cov hlau thiab txhuas.
Hlawv-los ntawm cov ntawv hlau tuaj yeem tshwm sim thaum tsim lub cev vuam los ntawm txhuas. Qhov shortcoming no yog deprived ntawm STP. Tsis tas li ntawd xwbKev siv hluav taws xob raug txo los ntawm 1.5-2 zaug, tus nqi ntawm cov khoom siv xws li vuam hlau, thaiv cov roj hluav taws xob txo qis.
Dhau li ntawm kev tsim tsheb, STP yog siv hauv cov hauv qab no:
- Kev tsim kho kev lag luam: aluminium txhawb trusses, choj spans.
- Rail thauj: ncej, log bogies, wagons.
- Shipbuilding: bulkheads, yam ntxwv yam.
- Aircraft: roj tso tsheb hlau luam, fuselage qhov chaw.
- Kev lag luam khoom noj: ntau lub ntim rau cov khoom ua kua (mis, npias).
- Kev tsim hluav taws xob: lub cev muaj zog, cov kav hlau txais xov parabolic.
Ntxiv nrog rau cov txhuas alloys, kev sib txhuam do vuam yog siv kom tau cov khoom siv tooj liab, piv txwv li, hauv kev tsim cov thawv tooj liab rau kev pov tseg cov roj hluav taws xob siv hluav taws xob.
nyiaj pab STP
Kawm FSW ua rau nws muaj peev xwm xaiv cov qauv vuam thaum koom nrog ntau pawg ntawm cov hlau. Txawm hais tias qhov tseeb tias thaum xub thawj FSW tau tsim los ua haujlwm nrog cov hlau uas tsis tshua muaj melting point, xws li txhuas (660 ° C), tom qab ntawd nws pib siv los koom nrog nickel (1455 ° C), titanium (1670 ° C), hlau. (1538 ° C).
Kev tshawb fawb qhia tau hais tias cov vuam tau txais los ntawm txoj kev no tau sib raug zoo hauv nws cov qauv rau cov hlau ntawm cov khoom yuav tsum tau welded thiab muaj cov ntsuas lub zog ntau dua, cov nqi zog qis dua thiab qis qis deformation.
YogQhov kev xaiv vuam hom lav qhov ua tau raws li cov khoom siv vuam thiab cov hlau raug welded raws li cov ntsuas hauv qab no:
- qaug zog:
- flexural thiab tensile zog;
- tuag.
Qhov zoo dua lwm hom vuam
STP muaj ntau yam zoo. Ntawm lawv:
- Tsis muaj tshuaj lom. Tsis zoo li lwm yam, tsis muaj hluav taws xob arc hlawv, vim tias cov hlau molten evaporates hauv thaj tsam vuam.
- Ntaus seam tsim nrawm, ua rau lub sijhawm voj voog nrawm dua.
- Txo nqi hluav taws xob ib nrab.
- Tsis xav tau kev ua haujlwm ntxiv ntawm qhov vuam. Cov Kev Sib Nqus Stir Tool tsim ib qho zoo meej weld yam tsis xav tau stripping.
- Tsis xav tau cov khoom siv ntxiv (vuam hlau, cov pa hluav taws xob, cov khoom siv hluav taws xob).
- Lub peev xwm tau txais cov pob qij txha hlau uas tsis muaj rau lwm hom vuam.
- Tsis muaj kev npaj tshwj xeeb ntawm cov npoo vuam yog qhov tsim nyog, tshwj tsis yog kev ntxuav thiab degreasing.
- Tau txais cov qauv vuam homogeneous yam tsis muaj qhov hws, ua rau kev tswj tau yooj yim dua, uas yog tswj hwm kev sib txhuam do vuam GOST R ISO 857-1-2009.
Yuav ua li cas qhov zoo ntawm cov vuam yog kuaj
Qhov zoo ntawm vuam yog kuaj los ntawm ob hom kev tswj. Thawj qhov cuam tshuam nrog kev puas tsuaj ntawm cov qauv tsim los ntawmkev sib txuas ntawm ob feem. Qhov thib ob tso cai rau kev txheeb xyuas yam tsis muaj kev puas tsuaj. Cov txheej txheem xws li kev tswj kho qhov muag, kev kuaj audiometric yog siv. Nws pab txiav txim seb muaj qhov pores thiab inhomogeneous inclusions uas degrade tus yam ntxwv ntawm seam. Cov txiaj ntsig ntawm kev tswj lub suab yog ib daim duab qhia pom tseeb ntawm qhov chaw uas lub suab acoustic deviates los ntawm tus qauv.
Qhov tsis zoo ntawm txoj kev
Nrog ntau qhov zoo, txoj kev sib txhuam vuam muaj qhov tsis zoo:
- Tsis muaj kev txav mus los. STP suav nrog kev sib txuas ntawm qhov chaw ruaj khov, ruaj khov hauv qhov chaw. Qhov no imposes tej yam khoom ntawm kev sib txhuam do vuam cov cuab yeej, xws li immobility.
- Kev siv ntau yam tsawg. Cov cuab yeej loj loj tau teeb tsa los ua tib hom kev ua haujlwm. Hauv qhov no, cov khoom siv rau vuam yog tsim los rau cov haujlwm tshwj xeeb. Piv txwv li, rau vuam tsheb sidewalls ntawm lub conveyor, thiab tsis muaj dab tsi ntxiv.
- vuam seam muaj cov qauv radial. Hauv qhov no, nrog rau qee hom deformation lossis thaum lub sijhawm ua haujlwm hauv qhov chaw nruj, weld qaug zog tuaj yeem tsim.
Ntau yam ntawm STP raws li txoj cai ntawm kev ua
Cov txheej txheem vuam raws li kev sib txhuam tuaj yeem muab faib ua ntau hom:
- Txoj kev sib txhuam. Lub ntsiab lus ntawm txoj kev yog kom tau txais kev sib txuas mus tas li tsis yog los ntawm qhov kev txiav txim ntawm qhov kev hloov pauv, tab sis vim yog qhov txav ntawm qhov sib txheeb ntawm ib leeg. Ua rau ntawm qhov chaw ntawm qhov chaw sib cuag, lawv tsimkev sib txhuam thiab yog li ntawd kub heev. Nyob rau hauv lub siab, cov nyob ib sab yog melted, thiab ib tug welded ob leeg yog tsim.
- Radial vuam. Txoj kev no yog siv rau kev tsim cov thawv loj-ntev, tsheb ciav hlau tso tsheb hlau luam. Nws boils mus rau qhov tseeb hais tias cov pob qij txha ntawm qhov chaw yog rhuab los ntawm ib tug rotating nplhaib hnav khaub ncaws sab nraum. Los ntawm kev sib txhuam, nws ua rau qhov kub thiab txias ze rau lub melting point. Ib qho piv txwv ntawm kev lag luam siv cov thev naus laus zis no yog Sespel, Cheboksary tank tsheb tsim khoom. Kev sib txhuam do vuam siv ntau qhov kev ua haujlwm vuam.
- Txoj welding. Qhov ntau yam no hloov qhov kev sib txuas rivet. Hom no yog siv rau kev sib tshooj sib tshooj. Lub rotating tus pin ntawm qhov chaw ntawm kev sib cuag heats qhov chaw yuav tsum tau welded. Los ntawm qhov kub thiab txias, melting tshwm sim, thiab tus pin nkag mus rau hauv. Txias cia, nws tsim kom muaj kev sib txuas ruaj khov.
Ntau yam ntawm STP los ntawm qib nyuaj
Vuam kev ua haujlwm uas siv kev sib txhuam tuaj yeem muab faib ua cov qauv thiab ntim. Lub ntsiab sib txawv ntawm cov ntau yam yog hais tias nyob rau hauv thawj rooj plaub, lub weld yog tsim nyob rau hauv ob-dimensional qhov chaw, thiab nyob rau hauv lub thib ob - nyob rau hauv peb-dimensional qhov chaw.
Yog li, rau cov pob qij txha, cov khoom siv vuam vuam ESAB tau tsim lub tshuab 2D LEGIO. Nws yog customizable kev sib txhuam do vuam system rau ntau yam uas tsis yog-ferrous hlau. Cov pab pawg loj sib txawvcov cuab yeej tso cai rau koj los txuas qhov chaw me me thiab loj. Raws li cov cim, LEGIO cov cuab yeej muaj ntau qhov kev teeb tsa, uas sib txawv ntawm cov vuam taub hau, muaj peev xwm vuam nyob rau hauv ob peb axial cov lus qhia.
