Rau cov paroj kav dejwelding, qhov zoo yog qhov nyuaj rau kev tswj thiab tsis yooj yim kom ua tiav qhov yuav tsum tau vuam slag tsis pub sab hauv, txawm li cas los xij, siv tau zoo dua thiab dav siv vuam thim rov qab yog tsim, phau ntawv arc vuam txoj kev los npog.Nyob rau hauv txoj kev no arc ntshiab, vuam kev ua haujlwm yog yooj yim, tsis tshua muaj pores, slag, tsis tiav kev nkag mus thiab lwm yam weld defects tom qab, lub sijhawm no, vim muaj cov kab me me, yog li thaj tsam me me ntawm tshav kub, me me deformation thiab tawg nyiam.

Tungsten inert gas welding luv luv TIG (Tungsten Inert Gas Weiding) vuam.Nws yog nyob rau hauv kev tiv thaiv ntawm inert roj, kev siv tungsten arc generated los ntawm cov electrode thiab workpiece puag cov ntaub ntawv thiab cov kub yaj muab tub lim hlau (filler xaim yog siv) yog ib txoj kev vuam.Nruam welding shielding gas ejected los ntawm lub nozzle ntawm lub teeb, lub arc yog tsim nyob ib ncig ntawm lub txheej tiv thaiv yog cais los ntawm cov pa roj, kom tsis txhob muaj teeb meem cuam tshuam rau tungsten tshav kub cuam tshuam cheeb tsam nyob ib ncig ntawm lub pas dej ua ke weld, tso cai rau cov zoo welds.

TIG welding qhov zoo:

1) TIG vuam tuaj yeem vuam hlau thiab ntau dua, argon vuam cheeb tsam tuaj yeem raug cais tawm ntawm cov huab cua ib puag ncig, nws tsis yaj cov hlau, thiab cov hlau tsis hnov ​​​​tsw.TIG vuam txheej txheem, arc vuam thiab tsis siv neeg scavenging nto oxide zaj duab xis.Yog li ntawd, kev vam meej ntawm lwm txoj kev vuam tau yooj yim oxidized yooj yim welded, nitriding, tshuaj reactivity thiab muaj zog non-ferrous hlau, stainless hlau thiab ntau yam alloys.

2) tiv thaiv cov nyhuv, zoo weld zoo.Ar yog ib qho ntawm feem ruaj khov thiab inert roj uas tsis hnov ​​​​mob nrog cov tshuaj tiv thaiv hlau, soluble hauv cov kua hlau tsis tsim cov pores, yog li nws yog kev tiv thaiv zoo heev.Vuam txheej txheem yog ib qho yooj yim hlau melting thiab crystallization txheej txheem, thiab yog li ntawd ib tug zoo weld zoo.

3) Vim lub compression thiab txias ntawm lub arc los ntawm argon txaus, vuam kev nyuaj siab thiab deformation yog me me, lub arc tshav kub concentration thiab siab kub argon, yuav xyuas kom meej tias cov weld cag nkag mus, me me tshav kub-tshem cov pob qij txha, me me vuam deformation. thiab cracking nyiam.Tshwj xeeb tshaj yog rau loj welded steel cua quenching tendencies.

4) tungsten arc stability, txawm nyob rau hauv ib tug me me vuam tam sim no (<10A) tseem nyob rau hauv ruaj khov combustion, tshwj xeeb tshaj yog rau nyias, nyias phaj vuam cov ntaub ntawv.

5) Thaum tshav kub kub thiab muab tub lim hlau tuaj yeem tswj tau, thiab yog li ntawd yooj yim los kho cov cua sov tawm tswv yim tuaj yeem welded ntawm ntau qhov chaw, tab sis kuj yog txoj hauv kev zoo tshaj plaws kom ua tiav kev tawg paj.

6) Raws li cov xaim muab tub lim tsis dhau los ntawm arc, nws tsis tsim spatter, weld tsos.

7) Ar yog ib qho atom roj, me me tshav kub muaj peev xwm, tsis tshua muaj thermal efficiency, kub noj, ruaj khov combustion ntawm lub arc yog zoo heev, txawm nyob rau hauv tsis tshua muaj tam sim no tej yam kev mob thiab ib tug ntev arc, lub arc tseem ruaj khov, yooj yim rau kev khiav lag luam, yooj yim rau nruab. tswj weld zoo rau txoj kev nyuaj welding txoj hauj lwm tag nrho txoj hauj lwm welding.

TIG welding yog ib qho yooj yim rau kev khiav lag luam vim qhov zoo, nyob rau hauv xyoo tas los no, nws tau dhau los ua ib txoj hauv kev rau cov tuam txhab tsim hluav taws xob hauv kev teeb tsa thiab kev saib xyuas ntawm boiler cua sov nto raj welded.Nyob rau hauv cov xwm txheej ntawm qhov chaw tu, thiab kev ua haujlwm ntawm txoj haujlwm vuam los ntawm qhov chaw txwv, cov txheej txheem feem ntau siv yog hauv qab TIG vuam SMAW npog tag nrho lub ntsej muag lossis siv TIG vuam.
