TIG welding (T ungsten I nert G as), lossis tsis siv khoom siv vuam electrode yog thaum lub arc ignites ntawm tungsten electrode thiab cov khoom yuav tsum tau welded. Yog li, tsis muaj kev hloov pauv ntawm cov hlau molten hauv qhov sib txawv arc. Qhov no ua rau nws muaj peev xwm los pab txhawb kev kub hnyiab ntawm hluav taws xob arc thiab ua kom nws ruaj khov. Tsis tas li ntawd, tig vuam txo cov evaporation poob, tshem tawm cov hlau tawg thiab txwv cov nyhuv ntawm cov roj los ntawm cov arc kem ntawm cov hlau molten. Raws li qhov tshwm sim, qhov zoo ntawm qhov vuam tau nce mus rau qib tshiab, zoo meej dua.
Tig-welding tuaj yeem yog ntawm AC lossis DC, thiab nyob rau hauv rooj plaub tom kawg tsuas yog siv cov polarity ncaj qha, uas yog, thaum cov khoom yuav tsum tau welded txuas nrog lub davhlau ya nyob twg ntxiv, thiab cov khoom siv hluav taws xob tsis siv. yog txuas nrog lub minus davhlau ya nyob twg. Qhov kev xav tau los txuas rau hauv txoj kev no yog vim qhov tseeb tias yog tias koj hloov cov terminals, ces muaj peev xwm ntawm overheating ntawm refractory tungsten hlau thiab, yog li ntawd, nws kuj yuav txo qis. Tsis tas li ntawd, chipping lossis melting ntawm cov electrode tuaj yeem tshwm sim, ua rau muaj qhov cuam tshuam tsis zoo ntawm vuam.
Tig weldingimplies lub xub ntiag ntawm lub ntsiab hauv qab no nyob rau hauv lub tsim ntawm lub installation: ib tug AC los yog DC fais fab mov, ib tug arc tawm stabilizer, ib tug oscillator, ib tug tam sim no tswj ntaus ntawv, ib tug tam sim no mem tes generator, ib tug roj solenoid valve, thiab ib tug ntaus ntawv rau suppressing. cov khoom tam sim no.
Tig-welding yog hom kev sib koom ua ke zoo tshaj plaws, vim nws tso cai rau vuam ntau yam khoom ntawm txhua txoj haujlwm hauv qhov chaw.
Cov txheej txheem zoo ntawm vuam qhov chaw ua tiav vim qhov tseeb tias nws siv sijhawm me ntsis ntau dua li lwm hom vuam. Hauv qhov no, tig vuam tsuas yog siv thaum cov yam ntxwv zoo ntawm qhov tshwm sim vuam yog qhov tseem ceeb.
Ib yam tshwj xeeb ntawm hom vuam no yog qhov ntshiab argon yog siv los koom nrog txhua yam ntaub ntawv, thaum rau lwm hom vuam yuav tsum xaiv cov roj raws li cov hlau tau welded.
Tig-welding yog ib txoj haujlwm nyuaj thiab mob siab rau. Yog li ntawd, ib tug tshwj xeeb kev cob qhia tsim nyog welder yog xav tau los nqa tawm. Cov txheej txheem thev naus laus zis yuav xav tau kev txawj txaus los ntawm nws, vim nws yog qhov tsim nyog los xyuas kom meej txaus thiab raws sij hawm ntawm cov khoom muab tub lim nrog ib sab tes, thaum lub vuam teeb yuav nyob rau hauv qhov tod tes.
Thaum xaiv lub tshuab vuamQhov no yuav tsum tau coj los ntawm cov kev xav hauv qab no:
- Yuav tsum txiav txim siab lub zog ntawm lub tshuab vuam.
- kwv yees qhov nyuaj thiab qhov kev ua haujlwm tom ntej.
- Muab rau hauv tus account yam khoom siv tam sim no: ncaj qha lossis hloov pauv.
Koj yuav tsum paub tias qee lub tshuab vuam siv tau ob qho tib si ncaj qha thiab hloov tam sim no tib lub sijhawm. Qhov no yog tsim nyog rau welding cov khoom sib txawv xws li txhuas thiab hlau. Welding units muaj ntau yam ntawm cov nqi tam sim no ntawm 3 txog 500 A.
