Electrode - ib tug hlau pas nrig coated nrog rau kev npaj rau welding

Cov niaj hnub txheej txheem ntawm cov hlau cov khoom ntau lawm yuav siv qhov tseeb technologies. Qhov no pub rau cov khoom uas siv yoog mus raws tus ntawm kev thov. Ua li no, thov ib tug ntau yam ntawm cov ntaub ntawv muaj tej yam ntxwv.

Electrode - yog yuav tsum tau rau Vuam caij. Rau txhua hlau hom thiab nws ua cov txheej txheem siv ntau hom. Yog li ntawd, cov electrodes muaj ib tug heev ob peb hom.

General yam ntxwv

Raws li twb tau hais, lub electrode - yog ib tug cov ntaub ntawv uas muab kev koom tes nyob rau hauv tus txheej txheem ntawm arc welding. Lawv pib siv nyob rau hauv lub xyoo pua puv 19. Tab sis hnub no tus ntau ntau yam tau kev zoo dua cov yam ntxwv. Lawv cia koj kom ceev li lub manufacturing ntau lawm txheej txheem thiab txo cov nqi ndlwg ntawm cov ntaub ntawv, lub zog thiab thiaj li nyob. D.

Yuav kom weld conforms mus rau cov qauv thiab zoo qauv rau txhua tus hlau hom yog tsim nyog los xaiv ib tug yam ntawm electrode. Txwv tsis pub cov khoom yuav tsis zoo.

Nws yuav tsum tau muab sau tseg tias cov electrodes, ua me npaum li cas tshaj qhov nruab nrab, yog ua los ntawm cov neeg pluag-zoo cov ntaub ntawv. Yog li ntawd, ua raws li cov technology yuav tsum yuav yam khoom Vuam XYUAS TIAS MUAJ TSEEB manufacturers. Tsuas yog nyob rau hauv cov ntaub ntawv no muaj tsis muaj tsis ntseeg tias cov electrodes yuav tau ua nyob rau hauv raws li nrog tag nrho cov uas yuav tsum tau.

ntaus ntawv

Cov hlau pas nrig ntawm lub electrode yog tau kev tam sim no. Nrog rau qhov no tsim, cov hluav taws xob los rau ntawm qhov chaw yuav tsum tau kho, thiab cov wizard ua arc welding.

Yav tas los piav hais siv xwb uncovered. Niaj hnub no, cov khoom siv raws li hlau rau Vuam nyob rau hauv inert roj cua. Ib tug yam ntxwv ntawm lub electrode assumes hauv lub xub ntiag rau lawv ntawm ib tug tshwj xeeb txheej txheej. Mus nqa tawm kev ua hauj lwm lawv yuav tsum tau siv nyob rau hauv ntau txoj haujlwm, xav cov khoom hauv chav kawm ntawv.

Ua cov khoom manufacturers feem ntau yog universal nyob rau hauv cov nqe lus ntawm tam sim no. Nws yuav ua tau ib qhov rau pem hauv ntej los yog rov qab polarity, raws li zoo raws li cov tsiaj ntawv. Cov kev xaiv nyob rau lub zog ntawm cov hlau.

cov chav kawm electrodes

Raws li cov siv tau kev cai ntawm lub Vuam electrodes 4 chav kawm:

1. Cov khoom uas txais tag nrho cov kev cai ntawm lub ob leeg creation.
2. Electrodes uas daim ntawv thov nyob rau hauv yuav luag tag nrho cov lus qhia tsuas yog lub ntsug (upward).
3. Electrodes peb cov chav kawm ntawv, tsim los rau Vuam los ntawm cov saum toj kawg nkaus down, kab rov tav thiab nws qis hom.
4. Cov khoom siv rau qhov qis dua cov kev taw qhia.

Yuav kom xaiv cov lo lus uas peb ntawm cov electrodes siv Lavxias teb sab ntawv. Tab sis yog hais tias tus khoom no yog txawv teb, lub npav yuav tsum English cim. Cov ntau ntau yam yog xav paub ntau kim tshaj domestic sawv daws yuav. Piv txwv li, rau high-carbon steel nws muaj ib tug los tsab ntawv W. A thaum tshav kub kub-resistant steel alloyed ntawm no yog muag uas sau tias T.

Tsis tas li ntawd, niaj hnub electrodes yuav ua tau nonconsumable thiab consumable. Qhov kawg ntawm no, nyob rau hauv lem, yog muab faib ua ob hom - them los yog tsis. Txheej plays ib tug luag hauj lwm rau kev tiv thaiv ntawm lub arc ntawm cov cua.

Lub electrodes 4 mm nyob rau hauv lub cheeb yog feem ntau siv thaum lub sij hawm arc welding. Txawm li cas los, muag muaj cov khoom uas hais mus rau lub pas nrig ntawm 2.5 mus 5.0 hli.

ntau yam ntawm daim ntawv sau npe

Uas twb muaj lawm hom electrodes tso cai rau lawv los mus xaiv tus tsim hom rau txhua yam hauj lwm. Qhov no saib kuas zoo ua.

Ib tug tsis ncaj ncees lawm hom electrode ua ib tug ua ib tug tsis ua hauj lwm. Muaj ib daim ntawv teev cov ntsiab ntawm ntau yam ntaub ntawv yuav tsum tau welded:

• Thaum tshav kub kub-resistant hlau steels;
• high-hlau steels nrog tshwj xeeb;
• yam ntxwv steel;
• uas tsis yog-ferrous co;
• hlau.

Rau txhua ntawm lawv yuav tsum tau ib tug txawv hom ntawm electrodes. Cov craftsmen paub dab tsi hauv chav kawm ntawv ntawm cov khoom no yog tsim rau txhua txoj kev thiab yuav tsis tau siv, piv txwv li, rau Vuam electrodes siv rau Vuam cam khwb cia hlau.

hom ntawm coatings

Kev Txiav Txim electrodes cim yog ua tseem nyob rau lub hauv paus ntawm lawv txheej. Lawv qhia los ntawm cov tsiaj ntawv.

A - muaj ib tug acidic txheej (hlau oxide, silica, manganese).

B - puag lub tsho tiv no (calcium carbonate, poov hlau fluoride).

C - electrodes muaj cellulosic topsheet. Qhov no tej zaum yuav hmoov, cellulose los yog lwm yam organic compound.

P - Txheej ua los ntawm rutile. Cov txheej ntawm cov tshuaj yeeb dej caw ua tswvcuab txhais inorganic los yog organic tebchaw.

P - Lwm yam tsawg heev variants nyob rau hauv daim ntawv thov ntawm cov txheej. Lawv yog siv rau cov tshwj xeeb txheej txheem ua hauj lwm.

Nws nyob rau ntawm lub hom txheej thiab txoj kev siv electrodes. Yog li ntawd nws yog tsim nyog los paub lawv lub zog.

hauj lwm coatings

Acidic cim A electrodes muaj tej yam tshuaj lom zog. Feem ntau cov feem ntau, lawv purchase yog nqa tawm nyob rau hauv tej ntawm ib tug nqi ntawm 1 kg ntawm 70 rubles.

Los ntawm kev yuav khoom lub ntsiab ntau ntau yam ntawm cov hoob kawm B, nws yuav tsum tau nco ntsoov hais tias hais tias lawv yog siv rau cov Vuam tseem ceeb heev lug direct tam sim no ntawm alternating polarity. Lawv nqi kuj pib thaum 70 rubles. / Kg.

Mark D ua hauj lwm los tsim ib tug roj tiv thaiv cov ntaub ntawv uas. Qhov no electrode, tus nqi ntawm uas yuav ncav cuag 200 rubles. / Kg.

Zoo tsim thaum lub sij hawm siv thiab ua cov cov khoom hom R. additives muaj nyob rau hauv lub txheej muaj pes tsawg leeg, tsis tsuas yog muab cov roj shielding nto, tab sis kuj pab mus rau tsis muaj spatter. Ntawm kev muag khoom muaj cov zoo xws li cov nqi ntawm 700 rubles. / Kg.

Lwm yam ntau ntau yam tej zaum yuav tau muag txawm ib lub zuj zus. Lawv nqi nws txawv nyob ntawm seb lub hom hauj lwm.

subclasses

Rau cov electrodes rau carbon tsawg hlau steel nws koom 9 hom ntawm cov khoom. Qhov no MP-3, 6-TAU, ELN-3 UONI 13/45, 13/55, thiab hais txog. D. Lawv pab pawg neeg yog sau lo rau Y.

Rau alloyed constructional steels siv 5 hom electrodes. Lawv npav yog tsab ntawv L.

Yog hais tias koj xav tau mus ua hauj lwm nrog ib tug kub-resistant hlau steel, kis tau yam khoom xws li T. electrodes 9 nyob rau hauv pab pawg neeg no.

Cov pab pawg neeg no yog npaj rau high-hlau steel nrog tshwj xeeb cov yam ntxwv.

Nyob rau hauv nqa tawm deposition yog siv nrog cov los N. Qhov no enables cov electrodes rau weld lub khaubncaws sab nraud povtseg ntawm cov ntaub ntawv uas muaj kev cov yam ntxwv.

Yuav ua li cas hom ntawm tam sim no siv nyob rau hauv lub chaw ua hauj lwm kuj yog nyob ntawm cov khoom hom. Muaj ntau ntau ntau yam ntawm hnub no yog universal. Tab sis muaj cov narrowly teem subspecies. AC mus rau lub electrodes xws li MP-3, ELN, thiab sawv - UONI 13/55, 13/45.

Lub tswv yim rau Xaiv

Electrode - yog ib tug ntawm lub ntsiab arc welding, uas txiav txim qhov zoo tshaj ntawm cov khoom muag kawg. Yog li ntawd, nws xaiv yuav tsum tau mus them.

Nyob rau hauv tsis muaj cov ntaub ntawv yuav tau pheej yig khoom. Lawv ntau lawm yog feem ntau nqa tawm yam tsis tau raws li cov kev cai tswj yuav tsum. Nyob rau hauv tus txheej txheem, tej zaum lawv yuav ua rau sib yuav los yog yuav tsum tau tsis txaus kom tsim tau muaj zog pob qij txha.

Cov nqi ntau rau cov khoom uas muaj tuaj ib tug ncaj loj. Tab sis kom tau pheej yig dua, tab sis unsuitable rau lub hlau kev kho mob tsis paub electrodes. Lawv cov yam ntxwv yuav tsum siab ua raws li cov vuam tshuab rau ib qho hom hauj lwm. Savings nyob rau hauv cov ntaub ntawv no tsuas yog tsim nyog. Paub qhov npav electrodes, nws tseem tau mus xaiv lub hom ntawm cov khoom tsis muaj teeb meem.

Muaj cuab kav nrog cov khoom rau welding, nws muaj peev xwm yuav xaus lus tias tus electrode - yog ib yam tseem ceeb ntawm cov txheej txheem. Nyob rau lub hom thiab tsis zoo ntawm cov kev tshwm sim nyob rau hauv lub chaw ua hauj lwm.
