Kushandisa iyo isiriyo yekudzivirira gasi kana gasi kuyerera kunogona kukanganisa weld mhando, mutengo, uye kugadzirwa zvakanyanya. Chengetedza gasi inodzivirira yakanyungudutswa weld pool kubva kune kunze kusvibiswa, saka zvakakosha kuti usarudze gasi rakakodzera rebasa racho.
Kuti uwane mhedzisiro yakanaka, zvakakosha kuziva kuti ndeapi magasi uye gasi musanganiswa anonyatsokodzera zvimwe zvinhu. Iwe unofanirwawo kuziva mamwe matipi anogona kukubatsira optimize gasi kuita mukushanda kwako welding, izvo zvinogona kukuchengetedza mari.
Dzakati wandei dzekudzivirira gasi sarudzo dzegasi simbi arc welding (GMAW) inogona kuita kuti basa riitwe. Kusarudza iyo gasi inonyatso kuenderana neiyo base zvinhu, yekufambisa modhi, uye welding paramita inogona kukubatsira iwe kuwana zvakanyanya kubva mukudyara.

Kutadza Kudzivirira Gasi Kuita
Yakakodzera gasi kuyerera uye kuvharika kwakakosha kubva panguva iyo welding arc inorohwa. Kazhinji, matambudziko nekuyerera kwegesi anoonekwa pakarepo. Iwe unogona kunge uchinetseka kumisikidza kana kuchengetedza arc kana kuwana zvakaoma kuburitsa emhando welds.
Kupfuura nyaya dzemhando, kusasimba kwekudzivirira gasi kuita kunogona zvakare kukwidza mitengo mukushanda. Mwero wekuyerera wakanyanya kukwira, semuenzaniso, zvinoreva kuti uri kutambisa gasi uye kushandisa mari yakawanda pakudzivirira gasi pane yaunoda.
Kuyerera kwemazinga akanyanya kana kuderera anogona kukonzera porosity, izvo zvinozoda nguva yekugadzirisa nekugadzirisa zvakare. Kuyerera kwemitengo yakadzikira kwazvo inogona kukonzera kukanganisa kwe weld nekuti dziva re weld harina kuchengetedzwa zvakaringana.
Huwandu hwespatter hunogadzirwa panguva yewelding hunoenderanawo nekudzivirira gasi riri kushandiswa. More spatter zvinoreva nguva yakawanda uye mari inoshandiswa pakukuya postweld.
Nzira yeKusarudza Shielding Gasi
Zvinhu zvakati wandei zvinotarisa gasi rekudzivirira rakakodzera reiyo GMAW maitiro, kusanganisira rudzi rwezvinhu, simbi yekuzadza, uye weld transfer mode.
Material Type.Ichi chinogona kunge chiri chinhu chikuru chekufunga nezvekushandisa. Semuyenzaniso, kabhoni simbi uye aruminiyamu vane hunhu hwakasiyana chaizvo uye saka zvinoda akasiyana ekudzivirira magasi kuti awane mhedzisiro yakanaka. Iwe unofanirwawo kufunga nezvekukora kwezvinhu paunosarudza gasi rekudzivirira.
Filler Metal Type.Iyo yekuzadza simbi inoenderana neyakagadzika zvinhu, saka kunzwisisa zvinhu kunofanirwa kukupa zano rakanaka nezveyakanakisa gasi resimbi yekuzadza zvakare. Mazhinji weld maitiro ekutemerwa anosanganisira ruzivo rwekuti ndeapi gasi musanganiswa anogona kushandiswa neakananga masimbi ekuzadza.
Kudzivirira kwakaringana gasi kuyerera uye kuvhara kwakakosha kubva panguva iyo welding arc inorohwa. Iri dhayagiramu rinoratidza kuyerera kwakatsetseka kuruboshwe, iyo inovhara iyo weld dziva, uye mhirizhonga inoyerera kurudyi.
Welding transfer mode.Inogona kunge iri pfupi-circuit, spray-arc, pulsed-arc, kana globular transfer. Imwe neimwe modhi inofamba zvirinani nemamwe magasi anodzivirira. Semuenzaniso, haufanirwe kushandisa zana muzana argon ine spray transfer mode. Pane kudaro, shandisa musanganiswa wakadai se90 muzana argon uye 10 muzana carbon dioxide. Iyo CO2 level mumusanganiswa wegasi haifanire kudarika makumi maviri neshanu muzana.
Zvimwe zvinhu zvekufunga nezvazvo zvinosanganisira kumhanya kwekufamba, mhando yekupinda inodiwa pajoinhi, uye chikamu chakakodzera-up. Ko weld yapera here? Kana zvirizvo, izvo zvinokanganisawo kuti ndeipi gasi rekudzivirira raunosarudza.
Kudzivirira Gasi Sarudzo dzeGMAW
Argon, helium, CO2, uye okisijeni ndiwo anowanzo dzivirira magasi anoshandiswa muGMAW. Gasi rega rega rine zvakanakira uye zvinokanganisa mune chero yakapihwa application. Mamwe magasi anokodzera zvirinani pane mamwe kune anonyanya kushandiswa base zvinhu, ingave aluminium, mild steel, carbon steel, low-alloy steel, kana simbi isina tsvina.
CO2 uye okisijeni magasi anoshanda, zvichireva kuti anokanganisa zviri kuitika mudziva re weld. Maerekitironi emagasi aya anopindirana nedziva reweld kuti abudise maitiro akasiyana. Argon nehelium magasi anert, saka haaite ne base material kana weld pool.
Semuyenzaniso, yakachena CO2 inopa yakadzika kwazvo weld kupinda, iyo inobatsira welding gobvu zvinhu. Asi muchimiro chayo chakachena inogadzira arc isina kugadzikana uye yakawanda spatter kana ichienzaniswa neinosanganiswa nemamwe magasi. Kana weld mhando uye chitarisiko chakakosha, musanganiswa we argon/CO2 unogona kupa arc kugadzikana, weld pool control, uye yakaderedzwa spatter.
Saka, ndeapi magasi akabatana zvakanyanya neakasiyana base zvinhu?
Aluminium.Iwe unofanirwa kushandisa 100 muzana argon yealuminium. Musanganiswa weargon/helium unoshanda zvakanaka kana uchida kupinda mukati kana kukurumidza kufamba. Rega kushandisa okisijeni inodzivirira gasi ine aruminiyamu nekuti okisijeni inomhanya kupisa uye inowedzera chidimbu cheoxidation.
Simbi yakapfava.Iwe unogona kubatanidza chinhu ichi nemhando dzakasiyana dzekudzivirira gasi sarudzo, kusanganisira zana muzana CO2 kana CO2 / argon musanganiswa. Sezvo zvinhu zvichiwedzera kukora, kuwedzera okisijeni kune argon gasi kunogona kubatsira nekupinda.
Carbon steel.Nyaya iyi inofamba zvakanaka ne100 muzana CO2 kana CO2/argon musanganiswa. Yakaderera-alloy simbi. A 98 muzana argon / 2 muzana okisijeni gasi musanganiswa wakanyatsokodzera chinhu ichi.
Kushandisa gasi rekudzivirira risiri iro kana kuyerera kwegasi kunogona kukanganisa zvakanyanya kunaka kweweld, mutengo, uye kugadzirwa mumashandisirwo ako eGMAW.
Simbi isina ngura.Argon yakasanganiswa ne2 kusvika ku5 muzana CO2 ndiyo yakajairika. Kana iwe uchida yakawedzera-yakaderera kabhoni yemukati muweld, shandisa argon ine 1 kusvika 2 muzana oksijeni.
How-To Tips Optimize Shielding Gasi Performance
Kusarudza gasi rekudzivirira rakakodzera ndiro danho rekutanga rekubudirira. Kunatsiridza kuita - kuchengetedza nguva nemari - kunoda kuti iwe uzive mamwe maitiro akanaka anogona kubatsira kuchengetedza gasi rekudzivirira uye kukurudzira kufukidzwa kwakafanira kwedziva reweld.
Flow Rate. Iko kuyerera kwakaringana kunoenderana nezvinhu zvakawanda, kusanganisira kumhanya kwekufamba uye chiyero cheguyo pahwaro zvinhu. Kuyerera kwegasi panguva yewelding kunowanzoreva kuyerera, kuyerwa mumacubic tsoka paawa (CFH), yakanyanya kukwira, uye izvi zvinogona kukonzera matambudziko akadai seporosity. Kana chero maparamendi ekushongedza akachinja, izvi zvinogona kukanganisa kuyerera kwegasi.
Semuyenzaniso, kuwedzera waya yekudyisa kumhanya kunowedzerawo saizi yeweld profile kana kumhanya kwekufamba, zvinoreva kuti ungangoda mwero wepamusoro wekuyerera kwegasi kuti uve nechokwadi chekuvharika.
Consumables.Iyo GMAW pfuti inoshandiswa, inosanganisira diffuser, yekubata tipi, uye nozzle, inoita basa rakakosha mukuona kuti weld pool yakachengetedzwa zvakafanira kubva mumhepo. Kana muromo wakatetepa pakushandisa kana kuti diffuser yakavharwa ne spatter, gasi rekudzivirira rakawandisa rinogona kunge richisvika padziva reweld. Sarudza zvinobatika zvinoramba spatter buildup uye inopa yakakura yakakwana bhomba kuti ive nechokwadi chekuvhara gasi rakakwana. Zvakare, ive shuwa kuti yekubata tip recess ndeyechokwadi.
Gasi Preflow.Kumhanyisa gasi rekudzivirira kwemasekonzi mashoma usati warova arc kunogona kubatsira kuona kuti pane kufukidzwa kwakakwana. Kushandisa gasi rinofashamira kunogona kubatsira zvakanyanya pakusecha migodhi yakadzika kana mabhero anoda tambo refu yekubuda. Kufashukira kunozadza mubatanidzwa negasi usati watanga kunogona kubvumidza iwe kudzikisira mwero wekuyerera kwegasi, nekudaro kuchengetedza gasi uye kuderedza mitengo.
System Maintenance.Paunenge uchishandisa yakawanda gasi system, ita kugadzirisa kwakaringana kubatsira kukwenenzvera kuita. Yese yekubatanidza nzvimbo musystem ndiyo inokwanisika sosi yekudonha kwegasi, saka tarisa zvese zvinongedzo kuti uone kuti dzakasimba. Zvikasadaro, unogona kunge uri kurasikirwa neimwe yekudzivirira gasi iwe yaunofunga kuti iri kusvika kune weld.
Gasi Regulator. Iva nechokwadi chekushandisa regulator chaiyo zvichienderana nemusanganiswa wegasi wauri kushandisa. Kunyatsosanganisa kwakakosha pakudzivirira weld. Kushandisa isina kukodzera regulator yemusanganiswa wegasi, kana kushandisa iyo isiriyo mhando yezvibatanidza, zvinogona zvakare kukonzera kunetseka kwekuchengetedza. Tarisa maregulator nguva nenguva kuti uone kuti ari kushanda nemazvo.
Pfuti Updates.Kana uri kushandisa pfuti yechinyakare, tarisa mumhando dzakagadziridzwa dzinopa mabhenefiti, senge dhayamita diki yemukati uye mutsara wegasi wepombi, iyo inobvumidza iwe kushandisa yakaderera gasi kuyerera. Izvi zvinobatsira kudzivirira kusagadzikana mune weld pool uku uchichengetedza gasi.
