1. Ibisobanuro CO2 ikingira gusudira ni uburyo bwo gusudira gaze ikingira gaze arc gusudira ukoresheje gaze ya CO2 ifite isuku iri hejuru ya 99.8% (uburyo bwubunini) nka gaze ikingira.Inzibacyuho ngufi, spray yinzibacyuho na pulse spray inzibacyuho irashobora gukoreshwa mugusudira.Irashobora gukoreshwa mu gusudira ahantu, gusudira guhagaritse, gusudira gutambitse, gusudira hejuru hamwe no gusudira imyanya yose.Irakwiriye cyane cyane gusudira ibikoresho byumukara nkicyuma cya karubone, ibyuma bivangwa nicyuma.

2. Gutezimbere gazi ya dioxyde de gaze ikingira gusudira nubuhanga bushya bwo gusudira bwakozwe muri 1950.Mu kinyejana gishize, yateye imbere muburyo bukomeye bwo gusudira.Ikoreshwa cyane mu nganda z’imodoka, gukora imashini zubaka, kubaka ubwato, gukora za lokomoteri, gukora lift, gukora amashyiga n’amato, no gukora ibyuma bitandukanye ndetse n’imashini zitunganya ibyuma.Dioxyde de carbone ikingira gusudira ifite ibyiza byo gusudira neza, igiciro gito nigikorwa cyoroshye.Numwanzuro wabanjirije gusimbuza intoki arc gusudira hamwe no gusudira arc gusudira.Na gaze ya gaze karuboni ikingira gusudira biroroshye kubona NC gusudira kuri manipulator cyangwa robot, bizaba uburyo nyamukuru bwo gusudira mu ntangiriro z'ikinyejana cya 21.Kugeza ubu, gaze ikingira ikoreshwa muri gaze karuboni ikingira gusudira igabanijwemo CO2 na CO2 + ar.Insinga zo gusudira zikoreshwa ni cyane cyane manganese silicon alloy welding wire, ultra-low carbone alloy welding wire na flux cored welding wire.Ibisobanuro nyamukuru byinsinga zo gusudira ni: 0.5 ﹐ 0.8 ﹐ 0.9 ﹐ 1.0 ﹐ 1.2 ﹐ 1.6 ﹐ 2.0 ﹐ 2.5 ﹐ 3.0 ﹐ 4.0, nibindi.

3. Ibiranga 3.1 igiciro cyo gusudira.Gazi ya CO2 nigicuruzwa cyenga inzoga n’ibiti bivura imiti, bifite isoko ryinshi nigiciro gito.Igiciro cyacyo ni 40 ~ 50% gusa yicyuma cyo gusudira arc cyarohamye hamwe nintoki arc gusudira.3.2 umusaruro mwinshi, kwinjira cyane muri CO2 arc, ubujyakuzimu bunini bwo gushonga, umuvuduko mwinshi wo gusudira insinga no kwihuta.Umusaruro wacyo wikubye inshuro 1 ~ 4 iy'intoki arc gusudira.3.3.Isahani ntoya, isahani yo hagati ndetse nisahani yuzuye irashobora gusudwa.Guhindura isahani yoroheje mugihe cyo gusudira ni bito, kandi imyanya yose yo gusudira irashobora gukorwa.3.4 irwanya ingese zikomeye, hydrogène nkeya muri weld hamwe no guhangana neza.3.5 gukuraho slag ntabwo bisabwa nyuma yo gusudira.3.6 kubera arc ifunguye, biroroshye gukurikirana no kugenzura mugihe cyo gusudira.

4. Ibikoresho byo gusudira CO2 4.1.Gazi ya CO2 4.1.1co2 imitungo ya gaze ya CO2 itagira ibara kandi irasharira gato.Ubucucike ni 1.97kg / m3, buremereye kuruta umwuka.Iyo gaze ya CO2 ikanda kuri 5 ~ 7MPa mubushyuhe bwicyumba, ihinduka amazi.Amazi ya CO2 yoroheje ugereranije n'ubushyuhe bw'icyumba.Kuri 0 ℃, 0.1MPa, 1kg ya CO2 y'amazi irashobora kubyara 509l ya gaze ya CO2.

4.1Kuri 0 ℃, umuvuduko wuzuye ni 3.63mpa;Kuri 20 ℃, umuvuduko wuzuye ni 5.72mpa;Kuri 30 ℃, umuvuduko wuzuye ni 7.48 MPa.Kubwibyo, silindiri ya CO2 igomba kurindwa izuba cyangwa hafi yubushyuhe kugirango birinde guturika.

4.1.3 Ingaruka za gaze ya CO2 kumiterere yo gusudira
