Yepamusorosoro argon nomoto

Yakatarwa mishonga inoshandiswa pamba uye zviri maindasitiri, yaigadzirwa nesimbi dzavo alloys. Nokuti Zvinokosha zvakaisvonaka uye yepamusoro zvachose kubatana simbi zvigadzirwa nani nzira - the Fusion nomoto. Pakati nzira, panongova zvakachipa uye anobvumira kuwana unhu hwakanaka weld, argon nomoto anogona kunzi. Uyu mufananidzo chinhu chakakombama nomoto. Chinozoiswa nokuda chinhu chakakombama ichipfuta pakati asiri consumable (kazhinji - tungsten) electrode uye chakaumbwa workpiece. The electrode akatasva ari burner uye externally akapa kuna utsotso mapazi ose filler zvinhu haisi chikamu magetsi redunhu. Kumicheto nechigadziko simbi uye filler zvinhu unonyauka nokuda yeplasma chinhu chakakombama uye dzinoumba musono. To weld dziva kuburikidza burner kamwene mu otomatiki nzira iri kusvitsa inert gasi ndiyo argon. It kushanda asingadi kupinda namakemikari kusakarongeka pamwe yakaumbwa nesimbi yakanyungudutswa, uye magasi akaumba mune chinhu chakakombama wongoramba. Nokuti kuti Ar ndiyo 38% kunorema kupfuura mhepo, izvozvo pairi, displacing ratinoona magasi kubva weld rokufambira, saka kudzivirira uye kudzivisa panowanikwa urema ari welded rwakashodoka. Kuderedza weld porosity, anogona kuwedzera argon pamusoro 3-5% okisijeni, ipapo resimbi chinodzivirira kushingaira.

Argon nomoto inopa weld inotungamirwa na ingi ndege kana globular simbi chinja. Globular chinja zvinoguma rakasiyana akapararira uye haagoni kubudirira inogona kuenderera nomoto rikurumidze. Kwesayenzi Unhu vakawana kana musono iri kupfuura mune semiautomatic nomoto muna CO _2. Inkjet simbi kuchinjirwa kunopa argon nomoto panguva Welding dzenzvimbo pamusoro kukurukura I = 260A. In izvi chakanamwa nomoto anova akatsiga weld unhu hwakanaka. Asi kushandisa yakakwirira amperage kwakadaro kazhinji anoenderana kwesayenzi zvinodiwa muitiro (semuenzaniso, kunyanya rinopisa workpiece uye achinje zvivako dzendarama yakapambadzirwa simbi). Saka here kushandisa nokuchinja simba rinopiwa. Izvi zvinobvumira kuti chinja kuti ndege kuti kutapurirana simbi kare dzenzvimbo uchitaurirana I = 100A.

kuvesa paaishandisa non-consumable electrode kutakurwa rinokosha zano - imwe oscillator kwakabatana munguva kufanana simba kunobva. Kana argon nomoto rinoitwa pasi rakatumbuka ano, pashure kuvesa ari chinhu chakakombama riri kuitwa kuti oscillator stabilizer muoti, zvokudya kupinda chinhu chakakombama pulses kuburikidza kuchinja polarity. Izvi zvinoita kutsiga chinhu chakakombama.

Kana rikashandiswa kugara uno, kuti cathode uye anode kunoitika gogonera kupisa kusunungurwa (anenge 70% - panguva anode). Naizvozvo, steels, titanium alloys nedzimwe simbi pane aruminiyamu, kushandiswa ngaatarire polarity kuti maximize preform yanyungudika. Al nomoto rinoitwa pamusoro rakatumbuka razvino, izvo anobvumira kuparadza oxide firimu, pasina overheating chigadzirwa.

Nokuti Welding zvikamu akagadzirwa Stainless steels, aruminiyamu uye ayo alloys ringashandiswawo argon-chinhu chakakombama Welding pamwe consumable electrode. Zvisinei, ayo kukura kuri dzinokwanisa akamanikana kupfuura pamwe tungsten electrodes.

Rinoshandiswa zvose Chinyorwa uye zvaitika argon nomoto. Pakati ayo zvakwakanakira zvinosanganisira kukwanisa kubudisa remubatanidzwa zvibereko ukobvu diki pasina weld filler zvokuvakisa, basa-nzira kuenda pamusoro. Nzira iri kunaka nokuda Welding garo nzvimbo pombi zvesimbi. Inoumbwa weld ane zvakanaka rwokugadzira parameters. Argon chinhu chakakombama nomoto - ano, kupfuura yakakodzera yeimwe kuti yakapambadzirwa steels, titanium alloys, aruminiyamu.

Nokuda hama nyore nzira, argon Welding nemaoko hazvisi kuwanikwa chete welders ounyanzvi. Muchiitiko chino, nokuda shoma basa, kwete kukosha zvokuti pasi negoho acho, izvo ichikutadzisa kushandiswa dzaro pamwero mukuru kugadzirwa.
