Vuam yog ib lub tshuab kom tau txais kev ntseeg siab ntawm ib qho kev sib koom ua ke ntawm cov khoom ua los ntawm cov khoom siv, siv cov yas deformation thiab fusion ntawm cov khoom thaum rhuab.
Txhua hom vuam raug faib raws li txoj kev fusion. Nws tuaj yeem nqa tau los ntawm cov cua sov hauv zos lossis dav dav, nrog rau lawv cov kev sib xyaw ua ke. Ntxiv mus, qhov tshwm sim ntawm seam muaj tib yam ntxwv (mechanical thiab lub cev) raws li cov khoom yuav tsum tau koom nrog.
Hnub no nws yog ib qho nyuaj rau xav txog tej cheeb tsam hauv kev lag luam kev tsim kho qhov twg cov tshuab no yuav tsis siv. Nws tso cai rau koj kom ceev qhov chaw ua los ntawm cov ntaub ntawv ceramic, yas thiab ntau yam alloys thiab hlau.
hom hlau vuam tuaj yeem muab faib ua peb chav kawm tseem ceeb (nyob ntawm seb lub zog siv): mechanical, thermal thiab lawv ua ke - thermomechanical. Ib txoj kev siv ntau tshaj plaws yog arc, nws yog hu ua fusion vuam. Lub hauv paus thiab muab tub lim hlau yog melted los ntawm kev tsim ib qho hluav taws xob arc ntawm cov hlau yuav tsum tau welded thiab electrode. Lub pas dej weld yog tsim thiab, raws li qhov tshwm sim tom qab crystallization ntawm cov hlau txias,tsim muaj zog seam.
Thaum koom nrog cov nplooj ntawv tuab heev, thaum nws tsis tuaj yeem ua kom sov cov hlau hauv ib qho dhau los, ua ntej vuam, cov npoo ntawm qhov uas nyob ib sab yog beveled thiab dhau qhov thib ob. Tom qab ntawd ib qho kev sib xyaw ua ke tshwm sim thiab muaj kev sib txuas zoo nrog cov seam zoo tau txais. Thaum lub sij hawm tus txheej txheem, qhov kev sib txuas taw tes yog rhuab siv hluav taws xob tam sim no. Nyob ntawm daim ntawv ntawm kev sib txuas, hom vuam tau muab faib ua: pob tw, nyem, qhov chaw, seam, raws li txoj kev Ignatiev thiab seam-butt. Kev sib cuag welding tuaj yeem ua tau nrog kev hloov pauv, ncaj qha lossis pulsating tam sim no. Nws yog siv los koom nrog cov hlau me me, nrog rau ntau cov yas. Txoj kev tshiab no yog siv dav hauv xov tooj cua, hluav taws xob thiab hluav taws xob kev lag luam. Thiab nyob rau hauv lub 70s, lawv txawm pib siv nws nyob rau hauv cov tshuaj rau "fusion" ntawm cov pob txha nyob rau hauv cov ntaub ntawv ntawm complex fractures, uas txo lub sij hawm ntawm tus mob, thiab li no lub incapacitated lub xeev ntawm ib tug neeg.
Cov hom vuam xws li tsis kam, hluav taws xob arc thiab lwm tus tau dhau los ua qhov dav vim yog lub tshuab hluav taws xob thiab tshuab ua haujlwm ntawm cov txheej txheem tsim khoom.
Qhov no ua rau nws muaj peev xwm ua kom muaj kev sib txuas ntawm cov qauv nrog. siab technical thiab economic indicators.
Ntau hom vuam ua lub zogtuaj yeem siv ultrasound, laser hluav taws xob, kev sib txhuam, roj nplaim, thiab lwm yam. Lub zog thiab kev ntseeg siab ntawm cov pob qij txha welded, kev ua tiav thev naus laus zis tshiab, cov cuab yeej siv niaj hnub yooj yim thiab cov tswv yim pab txhawb rau kev siv vuam hauv ntau qhov chaw ntawm kev tsim kho thiab kho. ua haujlwm.
