High-tech argon vuam

Lub teeb ntawm cov khoom siv nyob rau hauv lub tsev thiab nyob rau hauv kev lag luam, ua los ntawm cov hlau thiab lawv cov alloys. Rau ib check thiab high-zoo tas mus li kev twb kev txuas hlau cov khoom zoo txoj kev - lub fusion welding. Ntawm cov txoj kev, kuj pheej yig thiab tso cai rau kom muab tau ib tug zoo zoo weld, argon vuam yuav muaj npe. Qhov no yog ib yam ntawm arc welding. Siv los ntawm cov arc hlawv ntawm qhov uas tsis yog-consumable (feem ntau yog - tungsten) electrode thiab ib tug hlau workpiece. Lub electrode yog mounted nyob rau hauv ib tug burner thiab externally txhab khoom mus rau melting cheeb tsam ntawm muab tub lim cov ntaub ntawv uas tsis yog ib feem ntawm lub hluav taws xob Circuit Court. Lub npoo ntawm lub hauv paus hlau thiab lub muab tub lim cov ntaub ntawv uas yog melted los ntawm ntshav arc thiab tsim ib leeg. Yuav kom Weld pas dej ua ke los ntawm cov burner nozzle nyob rau hauv tsis siv neeg hom nkag rau hauv lub inert roj yog argon. Nws suab tsis nkag mus rau hauv tshuaj sis raug zoo nrog cov molten hlau thiab lub gases tsim nyob rau hauv lub arc tsam. Vim lub fact tias Ar yog 38% hnyav dua cov huab cua, nws descends, displacing atmospheric gases los ntawm cov weld tsam, yog li tiv thaiv nws thiab tiv thaiv kom qhov tshwm sim uas tsis xws luag nyob rau hauv lub welded ob leeg. Yuav kom txo tau weld porosity, tej zaum yuav muab ntxiv rau lub argon ntawm 3-5% oxygen, ces ib tug hlau tiv thaiv yog kom nquag plias.

Argon vuam muab ib tug weld tsim los ntawm number case dav hlau los yog globular hlau hloov mus rau lwm. Globular hloov tau nyob rau hauv ib tug dav dispersion thiab yuav caum tsis cuag sustainable vuam txoj kev. Technological yam ntxwv tau thaum no leeg yog zuj zus tshaj nyob rau hauv semiautomatic vuam nyob rau hauv CO _2. Inkjet hlau hloov mus rau lwm muab argon vuam ntawm Vuam currents tshaj kev sib txuas lus kuv = 260A. Nyob rau hauv tus txheej txheem no lub vuam yuav ruaj khov weld zoo zoo tuaj. Tab sis daim ntawv thov ntawm xws li high amperage feem ntau sau raws nkaus Ii hauj yuav tsum ntawm tus txheej txheem (e.g., unduly heats lub workpiece thiab hloov cov khoom uas alloyed co). Nws yog yog li ntawd hu kom siv switching khoom siv fais fab. Qhov no tso cai rau kom hloov lub dav hlau hlau hloov mus rau lwm twb currents ze kev sib txuas lus kuv = 100A.

tiv cav tseb thaum uas siv cov non-consumable electrode nqa los ntawm ib tug tshwj xeeb ntaus ntawv - ib tug oscillator kev cob cog rua nyob rau hauv thaum uas tig mus nrog lub hwj chim qhov twg los. Thaum lub argon vuam yog ua rau alternating tam sim no, tom qab tiv cav tseb ntawm lub arc yog hloov mus rau lub oscillator stabilizer hom, pub mus rau hauv lub arc pulses los hloov tus polarity. Qhov no saib kuas lub stability ntawm lub arc.

Yog hais tias lub thov qhov tam sim no, lub cathode thiab anode tshwm sim sis tsis ncaj thaum tshav kub kub tso tawm (txog 70% - nyob rau ntawm anode). Yog li ntawd, steels, titanium alloys thiab lwm yam co tshaj txhuas, siv ncaj polarity maximize preform yog melted. Al vuam yog ua rau ib tug alternating tam sim no, uas tso cai rau yuav ua kom puas lub oxide zaj duab xis, tsis muaj overheating cov khoom.

Rau Vuam qhov chaw ua los ntawm stainless steels, txhuas thiab nws alloys tej zaum kuj yuav siv argon-arc vuam nrog consumable electrode. Txawm li cas los, nws tau txais yog considerably nqaim tshaj nrog tungsten electrodes.

Nws yog siv ob qho tib si los ntawm txhais tes thiab tsis siv neeg argon welding. Ntawm nws cov zoo muaj peev xwm mus tsim ib tug compound ntawm cov khoom ntawm me me thickness tsis weld muab tub lim cov ntaub ntawv, ua hauj lwm-txoj kev nkag tau mus rau saum npoo av. Cov qauv no yog zoo heev rau Vuam taub qab txoj hauj lwm ntawm cov hlau kav. Tsim los ntawm weld muaj zoo hauj tsis. Argon arc vuam - technology, feem ntau haum tebchaw rau alloyed steels, titanium alloys, txhuas.

Vim tus kwv tij simplicity ntawm txoj kev, argon Vuam tus kheej ob txhais tes yog tsis muaj nyob rau kev welders. Nyob rau hauv cov ntaub ntawv no, vim yog lub me me ntawm kev ua hauj lwm, tsis yog li ntawd ib qho tseem ceeb uas tsis muaj productivity ntawm tus txheej txheem, uas txwv nws siv nyob rau hauv loj-scale lawm.
