Tig sawv rau tungsten inert roj vuam - pom cov kauj ruam vuam uas tau lees paub thiab ua haujlwm zoo ib yam rau gtaw (roj tungsten arc vuam). Thaum "Tig tau" yog cov khoom muag ntau dua nyob rau hauv kev cob qhia, Fineration khw, thiab kev sib tham txhua hnub, thiab arc - raws li fusion.
Ua kom tawg lub ntsiab lus qab "Tig" qhia li cas cov txheej txheem ua haujlwm:
Tungsten: lub electrode siv nyob rau hauv tig vuam yog ua los ntawm tungsten (lossis tungsten alloys zoo li ceriated), uas yog tsis {{0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {0} {}}} Consumable. Qhov no txhais tau tias nws tsis yaj los yog ua ib feem ntawm weld- nws tsuas yog coj hluav taws xob thiab txhawb nqa lub arc. Tupsten tus siab heev melting point (tshaj 6,100℃f) tso cai rau nws los tiv thaiv lub zog kub ntawm ARC (txog 10,000 txog kev kawm ntawv F) tsis muaj kev txwv.
Inert roj: cov thaiv cov roj av -} hel}}}}}} pa taws, nitrogen, thiab hydrogen, thiab hydrogen. Cov roj av no yuav txwv tsis pub muaj cov hlau molten, ua rau porosity, brittleness, lossis oxidation. Cov inert ntawm cov roj ua kom huv si, paug - weld ywj siab ywj pheej.
Roj (implied nyob rau hauv "Tig"): Cov inert roj yog xa los ntawm TIG tsau, ntws ib ncig ntawm cov electrode thiab dhau ntawm weld pas dej los tsim kom muaj kev tiv thaiv. Cov pa roj no yog qhov tseem ceeb: tsawg tsawg, thiab cov kab mob tsis huv infiltrate; Ntau dhau, thiab muaj kev ntxhov siab cuam tshuam cov ntaub thaiv npog.
Zoo li nws cov counterpart gtaw, Tig vuam tso rau ntawm lub tungsten electrode thiab workpiece kom yaj lub hauv paus pib, tsim lub pas dej weld. Tus tub lim hlau (ib tus pas nrig cais) tau ntxiv ntawm tus kheej los ntawm tus neeg teb xov tooj thaum xav tau, muab meej tswj hwm ntawm Weld qhov loj me thiab lub zog. Rau cov ntaub ntawv nyias nyias (li nyias raws li 0.005 nti), Tig tau txawm tias weld tsis muaj tub lim hlau, fusing lub hauv paus uas hu ua "autrogenous vuam."
Qhov tseem ceeb tshaj plaws ntawm "Tig" yog cov ntsiab lus, tsis ua haujlwm: Ob qho tib si xa mus rau tib cov txheej txheem, muaj nuj nqis rau nws lub peev xwm los tsim cov khoom siv huv si, kho kom zoo li kev lag luam me me {1} kev tsim khoom, kev kho mob kho mob, thiab cov cuab yeej siv tshuaj kho mob, thiab kev kho mob hlau, thiab kev lag luam kho mob, thiab kev kho mob.
Nyob rau hauv luv luv, Tig (tungsten inert roj) vuam yog cov txheej txheem uas tau ua rau cov txheej txheem txhais tau tias: A tungsten electrode, thiab arc {{} raws li fusion. Txawm hais tias hu los yog gtaw, nws tseem nyob ntawm lub hauv paus ntawm vuam vuam, tshwm sim rau nws txoj kev tswj hwm thiab versatility hla cov hlau los ntawm titanium.
