Vuam argon - ib tug niaj hnub txoj kev ua hauj lwm nrog cov hlau

Muaj coob tus neeg paub txog cov roj thiab hluav taws xob welding. Tsis ntev los no nws tau tuaj mus rau hloov qhov ntau sophisticated txheej txheem ua hauj lwm nrog ntau hlau. Nws yog hu ua "argon welding." Yuav ua li cas distinguishes nws los ntawm lwm yam vuam?

Lub hauv paus argon burner yog lub siab tshaj plaws kub nonconsumable tungsten electrode. Qhov kev xaiv ntawm cov khoom no yog vim nws refractoriness. Nyob ib ncig ntawm nws muaj ib tug tej hub nozzle. Thaum lub sij hawm Vuam argon yog cua tshuab therethrough, ua inert roj. Kuaj thaum lub sij hawm kev lag luam ntawm cov roj vim lub fact tias thaum raug rau ib co hom hlau, xws li txhuas, Vuam argon kom txuag tau lawv los ntawm burning, Blue thiab crusting. Nws yog ib qhov inert roj tiv thaiv lub weld los ntawm lub xub ntiag ntawm huab cua, uas tag nrho cov teeb meem tshwm sim.

Yog li ntawd yog dab tsi yog txoj kev ua hauj lwm? argon vuam pib los ntawm lub sij hawm thaum cov kev kho mob qhov chaw nkag thiaj li hu ua "loj" (qhov no yog zoo xws li cov electrofusion). Sab tes xis tuav welder teeb los ntawm kev uas cov pa roj yog nkag, thiab sab laug - tshwj xeeb muab tub lim hlau. Txhua hlau yuav tsum tau muaj cov "lawv" hlau. Piv txwv li, thaum Vuam txhuas xwb khoom siv ntawm nws alloys.

Lub burner yog txawm peem rau nrog ib tug tshwj xeeb khawm, uas yog tshuab txais los ntawm cov mov ntawm cov roj thiab hluav taws xob tam sim no. Nruab nrab ntawm lub hlau electrode thiab ib tug hluav taws xob arc, uas ua hauj lwm pab raws li ib tug yooj yim cuab tam. Hais tias nws melts lub muab tub lim hlau thiab lub workpiece. Thaum lub me me thickness ntawm lub welded qhov chaw dopant tej zaum yuav rho. Txawm tias nws khees simplicity, argon vuam yuav tsum tau ib tug ntau ntawm kev los ntawm cov welder. Cov kev txawj thiab kev paub ntawm high-chav kawm ntawv tus kws nyob ntawm lub zoo ntawm soldering pob qij txha thiab functionality ntawm txuas ntxiv dua mus khoom.

argon vuam yog siv tsis tau tsuas yog thaum ua hauj lwm nrog txhuas. Nws yog ua tau rau "haus" steel, steel hlau, tooj liab, hlau, nyiaj, kub. Ntawm kev txaus siab yog lub chaw ua hauj lwm nrog rau feem ntau ntau industrial thiab domestic cov ntaub ntawv. Vuam ntawm stainless steel nrog argon tau ua heev nrov. Nws yog ntau npaum li cas txhim khu kev qha soldering, txij li thaum cov khoom zoo stitching thiab overlay welded, ris rau yuav luag txhua yam khoom ib tug. Qhov no yog ib tug ncaj lub sij hawm-siv cov txheej txheem uas yuav tsum tau tshwj xeeb kev cob qhia, niaj hnub cov khoom thiab high-zoo khoom.

Nyob rau hauv lub kawg, nws muab lub dag lub zog thiab kev ncaj ncees, thiab cov khoom pab tau lub neej nce. Vuam ntawm stainless steel argon ua rau tsim ntawm ib tug ntxeem tau oxide txheej (lub ntsiab tivthaiv uas chromium), ho weakening cov hlau thiab ua nws corrosion. Nyob rau hauv thiaj li tsis mus tshwm sim neej puas leeg vuam yog ua tom qab nws ntxiv ua.

Cam khwb cia hlau - ib cov khoom uas hloov nws cov qauv thaum rhuab, yog li qhov zoo tshaj ntawm nws vuam siv yog ib qhov nyuaj. Thaum koj ua hauj lwm nrog nws koj yuav tau siv tshwj xeeb fluxing neeg thiab rods, uas yog ua los ntawm graphite cov ntaub ntawv. Vuam hlau argon ua rau yus lub leeg, uas yog nyob ze rau lawv lub zog mus rau lub alloy.
