Ukufudumezaigesi exubile exubileyakhelwe ukuthuthukisa ikhwalithi yama-welds. Amagesi adingekayo egesi ehlanganisiwe nawo amagesi ajwayelekile wokuvikela ama-welding anjengeumoya ohlanzekile, I-Carbon Dioxide, ingonona, njll. Kusetshenziswa igesi exubile esikhundleni sokuvikelwa kwe-welding kunemiphumela emihle yokucolisa amaconsi ancibilikisiwe, ukukhuthaza ubushelelezi obuncibilikayo, ukuthuthukisa ukwakheka kwama-pores, futhi kuncishiswe kakhulu ekushiseni, futhi kudume neminye imboni.

Njengamanje, kusetshenziswa kakhuluAmagesi ahlanganisiweingahlukaniswa ngamagesi ahlanganisiwe kanambambili kanye namagesi ahlanganisiwe ahlanganisiwe ngokuya ngohlobo lwamagesi ahlanganisiwe.

Isilinganiso sengxenye ngayinye ngohlobo ngalunye lweigesi exubileingahlukahluka ebangeni elikhulu, elinqunywa ikakhulukazi ngezinto eziningi ezifana nenqubo yokufaka i-welding, impahla ye-welding, imodeli ye-welding wire, ziphezulu izidingo zekhwalithi ye-weld, zikhuphuka izidingo zokuhlanza igesi eyodwa esetshenziselwa ukulungiselela iigesi exubile.

Izingxenye ezimbili igesi exubile

I-Argon + Oxygen

Ukungeza inani elifanele leumoya ohlanzekileUkuya e-Argon kungathuthukisa ngempumelelo ukuqina kwe-arc futhi kuhlaziye amaconsi ancibilikisiwe. Izakhiwo ezisekelayo ze-Oxygen zokuzivumelanisa zingandisa izinga lokushisa lensimbi echibini elibiwe, zikhuthaze ukuhamba kwensimbi, zinciphise iziphambeko ze-welding, zenze i-welding speed, bese usheshisa isivinini se-welding futhi uthuthukise ukusebenza kwe-welding. Ngaphezu kwalokho, i-oksijini + igesi evikela i-Argon inezinhlobonhlobo zokusetshenziswa futhi ingasetshenziselwa insimbi ye-welding carbon, insimbi ephansi yensimbi kanye nensimbi engagqwali yobukhulu obuhlukahlukene.

I-Argon + Carbon Dioxide

I-Carbon Dioxide ingathuthukisa amandla we-weld kanye nokumelana nokugqwala, kepha igesi emsulwa evikela igesi igcwele kakhulu, engavumeli ukusebenza kwabasebenzi. Ukuyixuba nge-argon ezinzile kunganciphisa ngempumelelo isilinganiso sensimbi esihlabathini. Kusetshenziswa izilinganiso ezahlukene ze-oksijini + igesi ye-argon evikela inezinzuzo ezisobala zensimbi ye-welding carbon nensimbi engenasici.

I-Argon + Hydrogen

I-hydrogenIngabe ukunciphisa igesi esekelayo exhasayo engakwazi ukukhulisa amazinga okushisa we-arc kuphela, ukusheshisa isivinini se-welding, futhi kuvikele ukwehlisa isithunzi, kepha futhi kunciphise amathuba ama-co pores akha futhi avikele nezici ze-welding. Inemiphumela emihle kakhulu ye-welding kuma-alloys asuselwa ku-nickel, ama-nickel-copper alloys, nensimbi engenacala.

Izingxenye ezintathu igesi exubile

I-Argon + Oxygen + Carbon Dioxide

Le yingxube kagesi esetshenziswa kathathu esetshenziswa kakhulu, enemiphumela ehlanganisiwe yokuvikela yalezi zingxube ze-GEG CORDERNTS.Umoya ohlanzekileIsiza ukuhlanganiswa, ingahlaziya amaconsi ancibilikisiwe, ngcono ikhwalithi yesendlalelo nejubane le-welding; I-Carbon Dioxide ingathuthukisa amandla we-Weld kanye nokuphikiswa kokugqwala, futhi i-argon inganciphisa i-spatter. Okwe-welding yensimbi yekhabhoni, insimbi ephansi yensimbi kanye nensimbi engenacala, le ngxube yegesi ye-ternary inomphumela omuhle kakhulu wokuvikela.

I-Argon + Helium + Carbon Dioxide

AlulimoniIngakhuphula ukufakwa kwamandla okushisa, thuthukisa uketshezi olubunjiwe futhi lukhuthaze ukwakheka kwamandla. Kodwa-ke, ngoba i-Helium ingugesi we-inert, akunamthelela e-oxidation kanye ne-alloy evutha insimbi yensimbi. Ngakho-ke, ingasetshenziselwa insimbi ye-carbon kanye ne-alloy yensimbi yensimbi ye-arc ye-arc ye-arc ye-arc arc, i-all-post-steartuit ukuguqulwa kwe-welding, kanye nensimbi engagqwali yonke i-arl-post arl-porting arlc welding ngokulungisa izilinganiso ezihlukile.
