1. Tlhaloso CO2 khase e sirelelitsoeng ke khase ke mokhoa o sirelletsang khase oa tšepe o sebelisang khase ea CO2 ka bohloeki bo kaholimo ho 99.8% (mokhoa oa bophahamo) joalo ka khase e sireletsang. Phetoho e khuts'oane ea potoloho, phetoho ea spray le phetoho ea pulse e ka sebelisoa bakeng sa ho tjheseletsa. E ka sebelisoa bakeng sa ho tjheseletsa letheba, ho tjheseletsa ka ho otloloha, ho tjheseletsa ho otlolohileng, ho tjheseletsa holim'a hlooho le maemo ohle a ho tjheseletsa. E haholo-holo a loketse bakeng sa ho tjheseletsa thepa e ntšo tšepe tse kang k'habone tšepe, motsoako tšepe le celik.

2. Ho nts'etsapele tjheseletsa e matla ea khase ea carbon dioxide ke theknoloji e ncha ea ho tjheseletsa e ntlafalitsoeng lilemong tsa bo-1950. Lilemong tse mashome a mahlano tse fetileng, e se e fetohile mokhoa oa bohlokoa oa ho kopanya litšepe. E sebelisoa haholo indastering ea makoloi, mochini oa mechini oa kaho, moaho oa likepe, mochini oa literene, tlhahiso ea lifte, boiler le tlhahiso ea likepe tsa khatello, le tlhahiso ea meaho e fapaneng ea tšepe le mochini o sebetsanang le tšepe. Ho tjheseletsa ka khase ea carbon dioxide ho na le melemo ea boleng bo botle ba ho tjheseletsa, theko e tlase le ts'ebetso e bonolo. Ke qeto ea esale pele ea ho kenya sebaka sa ho tjheseletsa ka har'a arc ka letsoho le ho tjheseletsa selikalikoe. Ho tjheseletsa ka khase ea carbon dioxide ho bonolo ho elelloa ho tjheseletsa ha NC ho manipulator kapa roboto, e tla ba mokhoa o ka sehloohong oa ho tjheseletsa lekholong la bo21 la lilemo. Hajoale, khase e sireletsang e sebelisoang kh'oneng ea carbon dioxide e sirelelitsoeng e arotsoe ka CO2 le CO2 + ar. Mehala ea ho tjheseletsa e sebelisitsoeng ke terata ea manganese ka ho fetesisa ea manganese, ultra-low carbon alloy welding wire and flux cored welding wire. The tobileng ka sehloohong ea terata tjheseletsa ke: 0.5, 0,8, 0,9, 1.0, 1.2, 1.6, 2.0, 2.0, 2.5, 3.0, 4.0, joalo-joalo

3. Likarolo 3.1 theko e tlase ea tjheseletsa. Khase ea CO2 ke sehlahisoa sa libaka tsa joala le limela tsa lik'hemik'hale, tse nang le mehloli e pharaletseng le theko e tlase. Litsenyehelo tsa eona ke 40 ~ 50% feela ea tse kenngoang ka har'a arc welding le welding ea arc ea letsoho. Tlhahiso e phahameng ea 3.2, ho kenella ka matla ha CO2 arc, botebo bo boholo ba ho qhibiliha, sekhahla se phahameng sa ho qhibiliha ha terata ea tjheseletsa le lebelo le potlakileng la ho beha. Tlhahiso ea eona ke makhetlo a 1 ~ 4 ho feta a welding ea arc ea letsoho. 3.3 mefuta e fapaneng ea kopo. Tšepe poleiti, poleiti mahareng esita le poleiti teteaneng ka welded. Phetoho ea poleiti e tšesaane nakong ea tjheseletsa e nyane, mme maemo ohle a ho tjheseletsa a ka etsoa. 3.4 mafome a matla a mafome, haedrojene e tlase ho weld le ho hanyetsa hantle. Ho tlosoa ha slag ha 3.5 ha ho hlokehe kamora ho tjheseletsa. 3.6 ka lebaka la selikalikoe se bulehileng, ho bonolo ho lekola le ho laola nakong ea tšepe.

4. Lisebelisoa tsa ho tjheseletsa tsa CO2 4.1. Khase ea CO2 4.1.1co2 e na le khase e hloekileng ea CO2 ha e na mmala ebile e bolila hanyane. Boikarabello ke 1.97kg / m3, e leng boima ho feta moea. Ha khase ea CO2 e hatelloa ho fihlela 5 ~ 7MPa mocheso oa kamore, e ba metsi. Mokelikeli CO2 e batla e le mocheso mocheso oa kamore. Ho 0 ℃, 0.1MPa, 1kg ea mokelikeli oa CO2 e ka hlahisa 509l ea khase ea CO2.

4. Ho 0 ℃, khatello e matla ke 3.63mpa; Ho 20 ℃, khatello ea saturation ke 5.72mpa; Ho 30 ℃, khatello e matla ke 7.48 MPa. Ka hona, silindara sa CO2 se tla sireletsoa letsatsing kapa haufi le mohloli oa mocheso ho qoba ho phatloha.
