Yuav ua li cas mus ua noj hluav taws xob vuam? Yuav ua li cas mus ua noj ib ntsug leeg ntawm hluav taws xob welding. Raws li ua noj ua haus electrowelded hlau

Feem ntau nws yuav tsum tau mus cuag lub hlau qhov chaw los yog tawg tsam ntawm lub ntsiab lus. Muaj ob peb txoj kev los muab cov kev kawm no. Feem ntau cov feem ntau lub tebchaw ntawm hlau thiab steel qhov chaw siv txoj kev hluav taws xob welding.

Nyob rau hauv uas nws yog raws li?

Yuav ua li cas mus ua noj hluav taws xob vuam? Nyob rau hauv thiaj li yuav to taub lub hauv paus ntsiab lus, nws yog tsim nyog yuav tau nco qab cov physics ntawm cov ntaub ntawv kawm. Ib tug ntawm cov nyob ntawm tej ntawm lub vuam siv lub tshuab kev cob cog rua rau lub chaw ua hauj lwm daim. Nyob rau kev sib cuag nrog no nto tshwm sim ib qho hluav taws xob arc. Tus taw tes ntawm kev sib cuag yog tsim ib tug so, uas yog lawm ua tus sau nrog molten hlau thaum nws txav lub electrode. Cov npoo ntawm cov hlau qhov chaw yaj nyob rau hauv enormous kub thiab hloov mus rau hauv ib tug coherent tag nrho.

arc ignition txoj kev

Tej hau kev kawm yuav ua li cas ua noj rau lub hlau fais welding, nws yog tsim nyog los paub ib yam dab tsi txog tus qauv. Qhov kev ncua deb thiab siab kub hluav taws xob mem tes ntawm cov workpiece thiab lub electrode yog hu ua arc. Yuav kom tsim cov tej yam kev mob, muaj ob txoj kev:

• Nyob rau hauv thawj cov ntaub ntawv, lub electrode (sai sai kov) "strike sharply" nyob rau hauv hlau, zoo li ib tug match. Arc yuav tsum tau muaj arisen los tswj, ua additive rau hauv ob peb hli los ntawm cov ua hauj lwm nto ntawm cov hlau.
• Nyob rau hauv lub thib ob cov ntaub ntawv, lub electrode ntsis yog tsim nyog los sharply coj mus rhaub workpiece.

Cov uas ua arc yuav tsum tsis txhob tawm mus. Yog hais tias nws puas tau tshwm sim, ua ntej uas hluav taws xob vuam nqaws yuav tsum tau ntxuav kom tshem tawm scale. Tsis ua li ntawd ua rau cov tsim ntawm qhov.

Qhov tseem ceeb ntawm tam sim no rau welding

Muab xam los amperage coj electrode thickness yuav nyob rau hauv kev xyaum kawm yuav ua li cas ua noj hluav taws xob welding. Thaum tsis txaus tam sim no electrode yog nplaum, thiab cov arc - extinguished. Thaum siab tam sim no hlau yuav tsuag tawm thiab hlawv. Yog hais tias peb siv lub Vuam transformer, lub electrode 1 hli raws li ib tug tam sim no ntawm 30-35 A. Nyob rau hauv kev siv Vuam inverter electrode ntawm 3 hli raws li ib tug tam sim no ntawm 80 A. Yog hais tias qhov kev nce rau amperage, hlau yuav txiav.

Lub electrodes raug xaiv raws li nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawm cov hlau. Muaj ob peb hom muab tub lim cov ntaub ntawv uas:

• steel;
• bimetal;
• cam khwb cia hlau;
• tooj liab;
• dag.

Tag nrho cov ntawm lawv thiab sau lo index numerals denoting hais tias ib tug hlau thickness thiab hardness ntawm txhua hom siv.

Tej hau kev kawm yuav ua li cas ua noj rau hluav taws xob welding, nws yog tsim nyog los nco ntsoov tias nyob rau hauv thiaj li yuav tau high-quality welds electrodes yuav tsum sib haum mus rau lub thickness ntawm cov hlau.

Vuam tiaj ntawv hlau

Nyias hlau (1 mus rau 3 lub hli) taub qab tuaj koom tsis tau qhov khoob thiab additives, tau raws li zoo sib xws ntawm raws li sawv.

Rau ib tug zoo haum pob qij txha thicker los xij (3 mus rau 8 hli) npoo yuav tsum tau txiav nyob rau hauv txoj cai ces kaum. Cia ib kis ntawm cov ntawv txheeb mus rau 2 hli. Cov khoom thickness ntawm 8 hli yog kev cob cog rua rau lub ob-txoj kev welding. Rau tebchaw thicker ntug dav hlau yog txiav nrog ib tug bevel.

Qhov twg pib kawm ua noj ua haus hlau

Tej hau kev kawm yuav ua li cas kom zoo zoo ua noj hluav taws xob welding, pib nrog rau feem ntau yooj yim dab.

• Siav khoom xib rau kab rov tav nto (vuam rooj).
• Tack ntswj kom nruj rau lawv nyob rau hauv lub npoo thiab nyob rau hauv qhov chaw.
• Yuav kom muab tso rau hauv lub yas dhos thiab ib tug tshiab additive yog txuas mus rau lub clamp ib feem ntawm cov pawg.
• Chiv txaus siab yog electrode nqes hav (hais txog 75 degrees) nyob rau hauv cov kev taw qhia ntawm cov arc. Yog li ntawd nws yog tsim nyog los ua taw uas zoo li yuav raking lub molten hlau nyob rau ob leeg.
• Qhov kawg ntawm tus electrode muaj tshwm sim nyob rau hauv lub weld chaw. Los ntawm txoj kevcai ntawm inclination liab tusyees ntws los ntawm cov kub electrodes thiab txawm zoo rau cov menyuam tsim lub weld.
• Tom qab txias, lub workpiece yuav tau recapture slag nrog lub workpiece nto.

Lub sij hawm tom qab lub sij hawm, raws li kev yog tau, lub stitches yuav tau ua tag nrho cov smoother thiab ntau yog.

Yuav ua li cas yuav ua rau ib tug ntsug leeg

Yuav ua li cas mus ua noj ib ntsug leeg ntawm hluav taws xob vuam? Qhov loj tshaj plaws - mus pib, raws li tag nrho ntawm lub tswv yim pom zoo. Vuam ntsug pob qij txha zoo xws li cov mus ua hauj lwm horizontally, cia li ib tug me ntsis nyuab me ntsis. Prihvatyvayut workpiece nyob rau hauv ob los yog peb qhov chaw. Ces weld yog tsuas yog los ntawm cov hauv qab li, clinging nco los nco. Maj mam, tag nrho kis yog lawm ua tus sau nrog kub hlau. Yuav ua li cas mus kawm tau mus ua noj rau los ntawm hluav taws xob? Lub hom phiaj yog mus hauj lwm ua ke ob leeg sawv los ntawm melting lawv vuam arc, ib txhij steered rau tus hlau mob los ntawm cov kua hauv lub xeev rau cov rhuab kawg ntawm lub electrode.

Koj muaj peev xwm tsis brew leeg dauv, thiab lub thiaj li hu ua "yim", tab sis qhov no yuav lis tsuas yog ib tug tej tus kws khomob tshwjxeeb. Yog li ntawd, yog hais tias koj xav paub yuav ua li cas kawm tau mus ua noj ib ntsug leeg los ntawm hluav taws xob welding, nws yog pom zoo kom mus saib cov chaw ua hauj lwm ntawm ib tug tej welder, mloog advices masters. Thiab xwb ces pib cov txheej txheem koj tus kheej.

Yuav ua li cas yuav ua rau ib tug zoo nkauj thiab khov ces kaum leeg

Puas yuav ua rau qhov thiaj li hu ua "T-bar" lub leeg tsis yog raws li ib qho yooj yim mus kawm tau mus ua noj rau hluav taws xob welding. Qhov no ob leeg siv yog tias koj xav muab qhov chaw nyob rau ces kaum sib txawv. Hlau qhov chaw teem kom cov vuam trickled mus rau hauv lub ces kaum. Taag "nkoj" vuam feem lob los ntawm opposite sab. Nyob rau hauv tas li ntawd, ib tug ntug ntawm lub preform yog tsa ib tug me ntsis ntau dua. Lub vuam txoj kev yuav tsum pib uas muaj lub qab ntug. Nyob rau hauv cov ntaub ntawv no, ua tib zoo nram qab no rau cov lus qhia yuav ua li cas kom zoo zoo ua noj hluav taws xob welding, weld zoo yuav ho zoo tuaj.

Yuav ua li cas zoo tshaj plaws los mus siv rau hauv lub vuam siv lub tshuab

1. Laus welders muaj ib tug tswj magnetic kis, uas tso cai rau yuav tau kho tus quab yuam ntawm cov tam sim no, - transformer. Muaj ntau yam kev xaiv thiab cov qauv nrog dimmers thiab ntxiv txhawm chim nyob rau hauv cov thawj los sis theem nrab sab ntawm lub transformer.
2. Inverter units - ntau niaj hnub vuam ntaus ntawv. Ua hauj lwm los ntawm lub siab zaus transformer ntawm xws units muaj me me qhov ntev thiab tsis muaj ceeb thawj. Nyob rau hauv xws li, yuav tau tom ntseeg nkaws vuam hom. Xeem chaw yuav tsum tau ua tib zoo, txwv tsis pub, lub cav yuav sai sai yuav puas ntsoog.

Txoj kev rau vuam kav

Nyob rau hauv lub qhaj ntawv ntawm cov kev kawm yuav ua li cas ua noj electrofusion yeeb nkab, nws yog zoo dua rau ib tug tuab hlau. Nyob rau ntawm phab ntsa thickness ua ntau yam dhau mus. Multilayer vuam pab txoj kev txhua yam khoom ntawm lub resulting weld kev twb kev txuas yuav muaj zog.

Chiv welded ib nrab-ntiv nplhaib nyob rau hauv ib tug coj, ces - nyob rau hauv lub thib ob. Nyob rau hauv tus qauv ntawm reference weld "downward" yog 4 hli electrodes muaj ib tug organic sputtering. Thaum lub luv luv arc, relying rau cov duab ntawm lub "hood", teem saum thawv yog me me sab oscillations.

Thaum ua hauj lwm raws li txoj kev "hauv qab li" sharply txo ceev. Reference electrode ntawm transverse oscillations ua 3-5 hli.

Thaum Vuam Siv kav dej yog thawj tsim nyog los npaj thiab teem caij rau tag nrho cov ntaub ntawv uas nyob rau vuam lub rooj los yog lub rooj ntev zaum. Ces lawv ottsentrovyvayut thiab rub ua ke mus cuag tej yam vuam kis. Tua prihvatyvayut pob qij txha nruab nrab ntawm lawv.

Kav nrog me me txoj kab uas hla kev cob cog rua nruam vuam nrog ib tug loj lub cheeb - discontinuous yam. Tom qab kawm tiav ntawm tag nrho cov kev ntawm Vuam hlau ua hauj lwm nto ntxuav ntawm scale, cov tshuaj tsuag solidified slag. Ua kev soj ntsuam mus ntes ntes los yog hlawv-los ntawm kev, tawm hauv Craters los yog pores. Nyob rau hauv lub xub ntiag ntawm tsis zoo welded leeg qhov chaw ua restoration.

Rau koj tus kheej muaj kev ruaj ntseg koj yuav tsum ua hauj lwm thaum lub sij hawm Vuam suede hnab looj tes thiab hnab looj tes, ib tug welder hnav ib daim npog qhov ncauj nyob rau hauv tarpaulin los yog hnyav tawv khau thiab paj rwb robes. Yuav tsum tau nyob ze yuav tsum tau ib tug tua hluav taws los yog ib lub taub ntim dej.
