Kushongedzagasi rekudzivirira rakasanganiswayakagadzirirwa kuvandudza mhando yewelds. Magasi anodiwa pagasi rakasanganiswa ndiwowo magasi anowanzo shandiswa pakudzivirira welding akadai seokisijeni, kabhoni dhayiokisaidhi, argon, nezvimwewo. Kushandisa gasi rakasanganiswa panzvimbo pegasi rimwe chete kudzivirira kusungirirwa kwesimbi kune mhedzisiro yakanaka yekuchenesa madonhwe akanyungudutswa zvakanyanya, kukurudzira kutsetseka kwesimbi, kunatsiridza kuumbwa kwayo, uye kuderedza mwero wemaburi, uye kwakakurumbira zvikuru mukugadzira kusungirirwa kwesimbi, kucheka nedzimwe nzvimbo.

Zvikamu zviviri zvegasi rakasanganiswa

Argon+Okisijeni

Kuwedzera huwandu hwakakodzera hweokisijeniKuisa argon kunogona kuvandudza kugadzikana kwearc uye kunatsa madonhwe akanyungudutswa. Hunhu hunotsigira kupisa kweokisijeni hunogona kuwedzera tembiricha yesimbi mudziva rakanyungudutswa, kukurudzira kuyerera kwesimbi, kuderedza zvikanganiso zvekusveta, kuita kuti weld ive yakapfava, uye kukurumidzisa kumhanya kwekusveta uye kuvandudza kushanda zvakanaka kwekusveta. Pamusoro pezvo, gasi rekudzivirira reokisijeni + argon rine mashandisirwo akasiyana-siyana uye rinogona kushandiswa pakusveta simbi yekabhoni, simbi isina alloy yakawanda uye simbi isina ngura ine ukobvu hwakasiyana.

Argon+Carbon Dioxide

Kabhoni dhayiokisijeni inogona kuwedzera simba rekuweld uye kuramba ngura, asi gasi rekudzivirira kabhoni dhayiokisijeni rakachena rinopararira zvakanyanya, izvo zvisingabatsire kushanda kwevashandi. Kuisanganisa neargon yakagadzikana kunogona kuderedza mwero wekupwanya kwesimbi zvinobudirira. Kushandisa huwandu hwakasiyana hwegasi rekudzivirira okisijeni + argon kune zvakanakira pachena pakuweldsa simbi yekabhoni nesimbi isina ngura.

Argon+Hydrogen

Hydrogenigesi rinotsigira kupisa rinoderedza kupisa iro risingangogone kuwedzera tembiricha ye arc, kukurumidzisa kumhanya kwe welding, uye kudzivirira kuchekwa kwakaderera, asi zvakare kuderedza mukana wekuti CO pores iumbwe uye kudzivirira kukanganisa kwe welding. Ine mhedzisiro yakanaka ye welding pa nickel-based alloys, nickel-copper alloys, uye stainless steel.

Zvikamu Zvitatu Gasi Rakasanganiswa

Argon+Okisijeni+Kabhoni Dioxide

Uyu ndiwo musanganiswa wegesi unoshandiswa zvakanyanya muzvikamu zvitatu, une mhedzisiro yekudzivirira yemusanganiswa wegesi wezvikamu zviviri zviri pamusoro.OkisijeniInobatsira pakupisa, inogona kunatsa madonhwe akanyungudutswa, inovandudza kunaka kweweld uye kumhanya kwewelding; kabhoni dhayokisaidhi inogona kuwedzera simba reweld uye kuramba ngura, uye argon inogona kuderedza kupararira. Pakushongedza simbi yekabhoni, simbi isina alloy yakawanda uye simbi isina ngura, musanganiswa uyu wegasi reternary une mhedzisiro yakanakisa yekudzivirira.

Argon+Helium+Carbon Dioxide

Heliuminogona kuwedzera simba rekupisa, kuvandudza kuyerera kwedziva rakanyungudutswa uye kukurudzira kuumbwa kweweld. Zvisinei, nekuti helium igesi isina simba, haina simba pakupisa kwesimbi yeweld neoxidation. Nokudaro, inogona kushandiswa pakushongedza simbi yecarbon ne low alloy steel pulse jet arc, simbi yakasimba, kunyanya all-position short-circuit transition welding, uye stainless steel all-position short-circuit arc welding nekugadzirisa zviyero zvakasiyana.
