Ib electrode li txhuas. Nta ntawm lub vuam txoj kev

Aluminium tau ua ruaj khov nyob rau hauv tib neeg lub neej. Txhua txhua xyoo, nws noj yog ua. Nyob rau hauv kev lag luam thiab tsev neeg, muaj ntau ntau cov ntawm no lub hlau. Yuav kom tsim ib tug tshiab los yog repairing qub khoom rau ntau lub hom phiaj los ntawm cov txhuas electrode siv nyob rau hauv lub vuam txoj kev. Yuav ua li cas yuav siv nws, koj yuav tsum to taub ua ntej ua hauj lwm.

Cov khoom ntawm txhuas

Yuav kom to taub yuav ua li cas thov tau lub electrode rau lub vuam ntawm txhuas, nws yuav tsum tau to taub hais tias lub xam qhovkev zoo tshaj ntawm cov hlau.

Nplaim txhuas lub sij hawm oxidation nyob rau hauv cov huab cua yog them nrog ib tug oxide zaj duab xis. Nws yog ib qhov nyuaj rau yaj. Tsis tas li ntawd txhuas vuam electrode yuav tsum tshwm sim nyob rau hauv ib tug kev gaseous ib puag ncig. Txwv tsis pub, molten mob ntawm tshuaj nyob rau hauv cov huab cua yuav oxidize thiab yuav tsis tshuam mus rau hauv ib tug nkaus xwb substance. Lub leeg li tsim tsis ua hauj lwm.

Rau txhuas Vuam ib tungsten electrode yog siv ntau kim argon los yog ib tug sib tov thereof nrog Helium.

Txawm tias txhuas hlau yog melted sai dua steel, nws yuav tsum tau ua 1.2 lub sij hawm lub vuam tam sim no.

Hauv paus ntsiab lus vuam electrode

Yuav kom to taub yuav ua li cas brew txhuas electrode, nws yog tsim nyog los muab lub essence ntawm tus txheej txheem. Muaj ob lub ntsiab hom ntawm nws. Tus thawj ntiav ib tungsten vuam electrode nyob rau hauv lub ce thaum uas siv cov inert gases. Nws hu ua AC Tig.

Qhov thib ob yog cov siv ntawm coated electrodes tsis muaj melting siv ntawm inert gases.

Nyob rau hauv ob qho tib si no, cov kev cai hais txog melting ua xav tau tus oxide zaj duab xis. Rau lub hom phiaj no yog ib tug alternating los yog direct tam sim no rov qab polarity. Qhov no ua rau cathodic disbondment zaj duab xis. Lwm hom tam sim no electrode ntawm txhuas yuav tsis tau ua raws li nws txoj kev ua.

Vuam nrog coated electrodes

Vuam ntawm hlau Siv nrog ib tug tuab ntawm 4 mm daim tshwm sim siv coated electrodes. Qhov no hom yog xa mus rau raws li MMA.

Tej yam ntawm vuam muab ib tug tsawg zoo ntawm cov weld, ib tug txaus loj spatter thiab cov neeg pluag kev tshem tawm ntawm solidified dross. Xeem provokes tus tsim ntawm corrosion.

Lub electrode raws li niaj hnub txhuas weld tias tso cai tshuam tag nrho cov txhuas alloys. Cov txheej txheem yuav siv sij hawm qhov chaw los ntawm txoj kev ncaj qha tam sim no muaj ib tug rov qab polarity.

Mus rau qhov zoo ntawm cov leeg yog nyob rau hauv lub cev ntau, koj yuav tsum xub nqa tawm sov-up. Rau qhov nruab nrab thickness ntawm lub dawb paug nws yog 300 degrees, thiab rau cov nyuv - 400 degrees. Cua sov thiab cua txias gradual kom zoo allergic ntawm cov hlau thiab tsis txhob muaj cov tsim ntawm tej kab nrib pleb crystallization.

Vuam yuav siv sij hawm qhov chaw tsis tu ncua siv ib electrode. Lawv yuav tsum tsis txhob ua transverse deeg li hlau.

Vuam tungsten electrode

Cov yav tas los version vim tsis muaj zoo yog tsis tshua muaj siv los ntawm cov tub txawg. Niaj hnub no masters siv xws li hom ntawm tej hauj lwm raws li txhuas Vuam ib tungsten electrode nyob rau hauv inert roj cua.

Qhov no yog siv rau cov lug uas yuav tsum tau raws li siab xav tau. Tungsten electrode muab sutures nyiaj pab ntau tshaj zog thiab zoo nkauj.

Thaum ua tau zoo Vuam ua hauj lwm yog siv los tiv thaiv lub txhuas nto los ntawm oxidation argon los yog Helium. Arc nkag nrog alternating tam sim no. Nws muab ib tug zoo so ib zaj duab xis nyob rau hauv cov hlau.

Lub teeb yog tsiv tshaj lub muab tub lim hlau, es nyob rau hauv pem hauv ntej ntawm nws. Koj yuav tsum tau xav txog lub tshav kub dissipation system. Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb rau nyias workpieces.

Tsis tas li ntawd, yuav tsum paub hais tias siab dhau heev lawm ib tug khiav ntawm inert roj yuav ua nyob rau hauv cov huab cua sucked nyob rau hauv lub arc cheeb tsam. Dhau me me ib tug kom muaj nuj nqis ntawm cov roj los yog kev kub ceev kev ua tau zoo yuav ua rau lub fact tias cov txhuas nto yog tseem oxidized. Argon yog tsim nyog los pib ua ntaub ntawv rau 5 vib nas this ntawm arc burning. Tom qab nws breakage inert roj yog muab tawm tom qab 7 seconds.

Thaum familiarized nrog vuam tshuab, uas ntiav ib tug electrode ntawm txhuas, nws tseem tau mus nqa tawm no nyob rau hauv tsev. Txawm li cas los, ua ntej koj pib ib lub me ntsis zoo dua kev kawm rau ib tug ruaj piece. Ces tus leeg kom tau ib tug ca thiab khov kho.
