Vuam tooj liab - lub ntsiab lus tseem ceeb ntawm cov txheej txheem

Tooj yog hais txog co ntawm siab hluav taws xob thiab thermal conductivity zog. Tooj melts ntawm 1085 degrees Celsius, thiab raws los ntawm lwm kev kub ceev hlau.

Yuav ua li cas yog tooj liab vuam? Siv ib tug los ze zog saib!

Vuam yog nqa tawm tooj liab graphite, carbon, hlau electrodes, raws li zoo raws li cov roj nruab nrab. Technology ntawm graphite thiab cov pa roj carbon electrodes raws li nyob rau kev siv ntawm ib tug tungsten electrode, uas yog lub vuam arc. Lub leeg tsim nyob rau hauv cov ntaub ntawv no los ntawm melting cov muab tub lim cov ntaub ntawv thiab cov npoo ntawm qhov tsab xov xwm.

Tsis tas li ntawd, kom paub lub vuam ntawm tooj liab nrog cov pa roj carbon los yog graphite electrodes, nws yog tsim nyog los kho ntug weldments. Qhov no yuav ua tau los ntawm txoj kev sib tsoo hwj chim cov cuab yeej.

Vuam electrodes ua los ntawm tooj liab los ntawm kev siv ntawm kev tiv thaiv flux. Nyob rau hauv cov ntaub ntawv no, nws ua raws li ib tug flux boric slag los yog borax. Ua ntej welding, lub laum yog thov mus rau lub chamfer.

Tom qab lub flux yog qhuav, nws yog ua tau rau pib vuam ntawm tooj liab. Qhov no yuav tsum ntxiv cov ntaub ntawv uas. Feem ntau, xws li ib tug bronze los yog tooj liab hlau. Cov kab uas hla ntawm lub additives yog nyob rau ntawm cov khoom thickness. Rau check weld yuav tsum tau ua cua sov chamfer. Qhov no txoj kev yuav tsum tau ua ua ntej mus rau lub vuam ntawm tooj liab. Nyob rau hauv tas li ntawd, nws yog tsim nyog Pokrovka leeg thiab ceev ceev txias. Manufactured tooj liab vuam ntawm cov pa roj carbon thiab graphite electrodes nyob rau hauv ncaj qha tam sim no.

Yog hais tias steel yog siv rau qhov no electrode, ces tus electrode khoom yog kiag li nyob rau hauv cov ntaub ntawv yuav tsum tau welded. Feem ntau nws yuav siv ib tug variant ntawm bronze. Tam sim no qhov twg los yog ib tug vuam siv lub tshuab los yog lwm yam vuam transformers thiab cuab yeej tej.

Yuav kom Weld cov tooj liab tiv thaiv nrog inert gases, siv yaj thiab uas tsis yog-consumable electrodes. Yuav kom muaj xws li uas tsis yog-consumable tungsten rods rau consumable - tooj liab thiab bronze electrodes.

Rau tooj liab tungsten vuam pas nrig yog siv alternating thiab ncaj tam sim no rau Vuam tooj liab thiab bronze - qhov. Qhov tseem txhim khu kev qha thiab check vuam kev twb kev txuas yog xav kom Vuam tooj liab nyob rau hauv ib tug gaseous medium.

Argon vuam li cov feem universal txoj kev

Vuam tooj liab argon yog ib tug universal ib tug nrog ntau yam zoo. Qhov no tus txheej txheem no siv nyob rau hauv cov kev tshwm sim hais tias:

• zoo li yog ib qho tseem ceeb kom paub meej, Siv;
• Peb yuav tsum tau ua tib zoo ua ib lub qhov los yog keej;
• restore ib tug yav tas los lawm fixture.

Hom welders

Vuam apparatus - ib tug generic lub sij hawm rau ib tug tag nrho pawg ntawm cov zwj ceeb hom muaj lub hom phiaj pab kiag li lawm siv nyob rau hauv hluav taws xob arc melting vuam txoj kev. Cov tub txawg feem ntau hu ua welder Vuam hwj chim qhov twg los. Qhov loj tshaj kev thov rau cov khoom nrog phau ntawv vuam stick electrode.

Welders yog dej num raws li nram no:

- pab kiag li lawm rau kev ua tau zoo roj thiab kuj Vuam phau ntawv hom;

- li nrog semi-automatic thiab tsis siv neeg tswj ntawm lub vuam txheej txheem;

- pab kiag li lawm tshwj xeeb vuam: Vuam argon installation.

Nws yuav tsum tau muab sau tseg tias hnub no nyob rau hauv zoo kawg thov ntawm cov pejxeem yog cov welders tsev neeg hom.
