TIG tseem hu ua inert gas shielded arc vuam. Nws siv high melting point hlau raws li ib tug uas tsis yog-melting electrode ntawm lub arc, thiab siv inert gas (argon, helium los yog argon-helium mixed gas) raws li lub arc nruab nrab thiab tiv thaiv huab cua, yog li ntawd thaum lub sij hawm vuam txheej txheem arc thiab vuam pas dej ua ke. tsis cuam tshuam los ntawm huab cua puag ncig. TIG tuaj yeem txuas tau yooj yim oxidized tsis-ferrous hlau thiab lawv cov alloys, stainless hlau, high-temperature alloys, titanium thiab titanium alloys, thiab refractory active hlau (molybdenum, niobium, zirconium), thiab lwm yam. Nws mas welds nyias daim hlau nrog ib tug tuab ntawm tsawg mas 3mm. Rau cov tuab loj Cov qauv tseem ceeb xws li cov hlab ntsha siab, cov kav dej, thiab lwm yam tuaj yeem siv rau hauv paus vuam. Tungsten arc vuam yog ib txoj kev vuam uas tam sim no tau siv dav, feem ntau hauv kev tsim cov hlau hlau xws li aircraft tsim, nuclear zog, tshuaj, thiab textiles.
1. Qhov zoo
(1) Cov electrodes ua los ntawm cov hlau refractory passive tungsten los yog activated tungsten yuav tsis yaj thaum lub sij hawm vuam txheej txheem. Kev siv cov roj argon los cais cov huab cua tiv thaiv cov pa oxygen, nitrogen, thiab lwm yam roj los ntawm kev cuam tshuam rau lub pas dej arc thiab molten. Cov ntsiab lus ntawm cov hlau yuav tsum tau welded thiab vuam hlau tsis yooj yim hlawv (tsuas yog ob peb hlawv). Yog li ntawd, nws yog ib qho yooj yim kom tswj tau qhov arc ntev. Cov txheej txheem vuam yog ruaj khov thiab qhov vuam zoo yog qhov zoo.
(2) Flux tsis tas yuav tsum tau thaum lub sij hawm vuam, thiab tsis muaj slag rau saum npoo ntawm vuam. Nws yog ib qho yooj yim los soj ntsuam lub pas dej molten thiab weld tsim, thiab xyuas qhov tsis xws luag hauv lub sijhawm. Kev ntsuas tsim nyog tuaj yeem raug coj los tshem tawm qhov tsis xws luag thaum lub sijhawm vuam.
(3) Cov pa roj argon muaj cov nyhuv compression ntawm lub arc, yog li cov cua sov yog concentrated thiab lub pas dej molten me dua; qhov cua txias ntawm qhov ze-seam cheeb tsam los ntawm cov roj argon tuaj yeem ua rau thaj tsam cua sov ua rau nqaim thiab deformation ntawm cov welment txo. Lub welded sib koom ua ke muaj cov qauv nruj thiab cov khoom zoo txhua yam; Thaum welding stainless hlau, qhov corrosion kuj ntawm cov vuam, tshwj xeeb tshaj yog cov tsis kam mus rau intergranular corrosion, zoo dua.
(4) Txij li cov xaim xaim tsis dhau los ntawm qhov vuam tam sim no, yuav tsis muaj qhov sib txawv los ntawm kev hloov pauv ntawm arc voltage thiab tam sim no los ntawm kev xa dej xau, muab cov kev mob zoo rau kev tau txais qhov chaw sib tw. Lub arc ntawm tungsten argon arc vuam yog qhib arc. Cov kev tsis sib xws ntawm cov txheej txheem vuam yog ruaj khov, yooj yim rau kev kuaj xyuas thiab tswj, thiab yooj yim kom paub txog kev siv tshuab thiab siv vuam vuam.
2. Qhov tsis zoo
(1) Tungsten argon arc vuam siv roj rau kev tiv thaiv thiab tsis zoo rau cov cua sab nraud. Lub melting qhov tob yog ntiav, lub deposition ceev yog qeeb, thiab cov productivity yog tsawg. Ib qho me me ntawm tungsten electrode melts thiab evaporates, thiab tungsten hais nkag mus rau hauv lub pas dej molten yuav ua rau tungsten suav nrog, uas cuam tshuam rau qhov zoo ntawm cov vuam. Tshwj xeeb tshaj yog thaum tam sim no loj heev, tungsten electrode yuav raug hlawv tiag tiag thiab qhov tshwm sim ntawm tungsten suav nrog yuav pom tseeb.
(2) Piv nrog electrode arc vuam, kev ua haujlwm nyuaj dua, cov cuab yeej siv tau yooj yim dua, thiab kev tu kom huv rau qhov vuam yog qhov tshwj xeeb. Tus nqi tsim khoom yog siab dua li ntawm electrode arc vuam thiab submerged arc vuam.
