Kusarudza gasi risingashandiswi zvakanaka kunogona kukusiya uine ma weld azere nemaburi, mapopoma, kana simba risina kusimba—kunyangwe paunenge uchishandisa waya yeMIG yakasimba uye michina. Gasi reMIG re welding ringaita serisingaonekwe, asi ndiyo "nzira isingaonekwe" inokanganisa zvakananga hunhu hwe arc, nzira dzekufambisa simbi, uye hunhu hwekupedzisira hwe weld. Pazasi, tichatsanangura hurongwa hwesarudzo huri nyore kuti tikubatsire kusarudza gasi rekudzivirira rakakodzera rekushandisa kwako.
Hurongwa hweSarudzo: Tsvaga Gasi Rako Rakakwana rekudzivirira
Tichakurukura mibvunzo mitatu mikuru kuti titsanangure zvaungasarudza. Hapana zvimwe zvekufungidzira—kungosarudza zvaunoda chete zvichienderana nezvaunoda.
Mubvunzo 1: Chii chauri kushongedza?
Zvinhu zvesimbi ndizvo zvinhu zvekutanga uye zvinonyanya kukosha. Ngatitangei nezvinhu zvinonyanya kushandiswa tobva taenda kune simbi dzakakosha.
Simbi Nyoro (Chiitiko Chinonyanya Kuitika)
Pakugadzira gasi rekunamira simbi isina kusimba newaya yakasimba yeMIG, pane sarudzo mbiri dzinonyanya kukosha pamusika. Heino maitiro adzo:
Gasi reC25 (75% Ar, 25% CO2) - Sarudzo Yekutanga Yese
Nei ichishanda: Musanganiswa uyu weargon CO2 unopa arc yakagadzikana, kusawirirana kushoma kwewelding, uye chitarisiko cheweld chakatsetseka—kugadzirisa zvinonetsa zvikuru zve welding yesimbi isina kusimba. Inoderedza kurasikirwa kwe alloy element, inowedzera simba rekusunga weld, uye inoshanda kune akawanda maapplication, kubva pamapepa matete kusvika kumaplate ane ukobvu hwepakati. Ungave uri kuita short-circuit kana spray transfer, C25 inochengetedza maitiro acho akachena uye achidzorwa.C25
Zvakanakira: Mabasa mazhinji esimbi isina kusimba apo mhando, chitarisiko, uye nyore kushanda zvinokosha.
CO2 yakachena - Kutengeserana Kunochengetedza Mari
Nei ichishandiswa: CO2 yakachena yakachipa zvakanyanya pane magasi akasanganiswa, zvichiita kuti ikwezve mabasa akawanda ane bhajeti shoma. Inopawo kupinda kwakadzama, izvo zvinobatsira pakushongedza maplate akakora pasina kutsvedza. Kuchinjana: Tarisira arc "yakaoma", kusvibisa kwakawanda kwewelding, uye nzvimbo yakakombama yeweld. Uchapedza nguva yakawedzerwa pakuchenesa mushure mekushongedza, uye kurasikirwa kwealloy kwakakwira kana tichienzanisa neC25.
Zvakanakira: Simbi yakakora isina kusimba iyo chitarisiko chayo chisina kukosha uye mutengo wayo ndiwo unonyanya kukosha.
Zano renyanzvi: Kana uchisanganisa simbi isina kusimba uye uchida nzira yakachena, isina matambudziko, tanga neC25. Ndiyo sarudzo inonyanya kushandiswa pakushandisa waya dzakasimba dzeMIG.
Simbi isina ngura
Gasi rekuwedera resimbi isina ngura rinofanira kuchengetedza ngura uye kuona kuti rinowedera zvakanaka. Argon yakachena haizoshande pano—inoita kuti inyorove zvakanaka uye isasvibiswe zvakanaka.成形Sarudza gasi rine misanganiswa mitatu yakaita seAr + 2-5% CO2 + 1-2% O2 kana Ar + 90% He + 2.5% CO2. Izvi zvinosanganisa simbi yakanyungudutswa, zvinovandudza kupararira kweweld, uye zvinoderedza kurasikirwa kwealloy, zvichiita kuti simbi isingatsvi isina ngura isapararire.
Aruminiyamu
Aruminiyamu inoda argon yakachena kana musanganiswa weargon-helium. Basa guru reArgon nderekuchenesa firimu realuminium oxide (chinhu chinodiwa kuti pave ne welds dzakasimba) uye kudzikamisa arc. Kuwedzera helium kunowedzera kupisa, izvo zvinobatsira nezvikamu zvearuminiyamu zvakakora nekuwedzera kupinda uye kumhanya kwe welding. Dzivisa chero CO2 kana O2 mugasi rekudzivirira aluminium - izvi zvinokonzera porosity uye brittle welds.
Mubvunzo 2: Ndezvipi Zvivakwa Zvekunamira Zvaunokoshesa?
Sarudzo yako yegasi inokanganisa zvakananga maitiro uye mashandiro eweld yako. Enzanisa gasi nezvinhu zvako zvaunonyanya kukoshesa:
- Unoda mabhora akafara uye kupinda kwakadzika (zvakanaka pamapepa matete) here? Shandisa chiyero chepamusoro cheargon - inonyorovesa arc uye inodzivirira kutsva.
- Unoda kupinda mukati memvura yakadzika kuti uwane maplate akakora here? CO2 yakachena kana musanganiswa weCO2 wakakwira unopa kupisa kwakasimba.
- Unoda kukurumidza kupinza simbi? Misanganiswa yeArgon-helium kana C25 inobvumira amperage yakawanda pasina kupararira kwakanyanya, zvichiwedzera kugona kwayo.
- Unovenga kuchenesa mushure mekukwesha? C25 kana mimwe misanganiswa yakawanda yeargon inoderedza kupwanya kwewelding zvakanyanya, zvichikuchengetedza nguva yekukuya nekupedzisa.
Mubvunzo 3: Bhajeti Yako Yakaita Sei?
Ngatishandisei nzira dzinoshanda—bhajeti rinoita kuti pave nesarudzo dzakawanda. Heino kupatsanurwa kwemitengo chaiyo, kupfuura mutengo wemafuta chete:
- CO2 yakachena: Mutengo wepeturu wakaderera pakutanga, asi mitengo yakakwira yenguva refu kubva panguva yekuchenesa yakawedzerwa uye marara esimbi eMIG akawedzera.
- C25 Gas: Mutengo wegesi wakakwira kupfuura CO2 chaiyo, asi mitengo yese yakaderera nekuda kwekumhanya kwekunamira nekukurumidza uye kugadzirisa patsva kushoma. Hapana mimwe michina inodiwa—silinda imwe chete inosanganiswa.
- Misanganiswa mitatu kana argon-helium: Mutengo wakakwira wezvinhu zvakakosha, asi zvakakosha kudzivirira kutadza kudhura kweweld.
Heino dambudziko: Kana usina bhajeti rakawanda asi uchibatanidza simbi yakawanda isina kusimba, CO2 yakachena inogoneka—inongodiwa chete kuti uchenese nguva. Kune zvitoro zvakawanda, C25 inopa mwero wakanakisisa wemutengo uye mashandiro.
Mazano Akakosha: Usaparadza Sarudzo Yakanaka yeGasi neKugadzirisa Zvisina Kunaka
Kunyangwe gasi rekudzivirira rakakodzera harizobatsiri weld yako kana ukakanganisa mwero wemafuta kana kuoma kwegasi. Izvi hazvigone kutaurwa nezvazvo:
Mwero weKuyerera kweGasi (CFH/LPM)
Kuyerera kushoma kunoita kuti weld yako isadzivirirwe (zvichikonzera kuyerera kweweld); kuwanda kwayo kunokonzera kutenderera (kunosveta mhepo, zvichikonzerawo kuyerera kwemvura). Kune akawanda mashandisirwo ewaya dzakasimba dzeMIG:
- Simbi isina kusimba (C25 kana CO2 yakachena): 15-25 LPM (30-50 CFH)
- Simbi isina ngura (musanganiswa wezvikamu zvitatu): 18-28 LPM (38-60 CFH)
- Aruminiyamu (argon/argon-helium): 20-30 LPM (42-63 CFH)
Kuoma kwegesi
Hunyoro huri mugasi rinodzivirira hunokanganisa mweya. Hunokonzera kupwanyika kwemhepo uye hunopedza simba remagetsi. Shandisa mudziyo wekuomesa/sefa mugasi rako, uye tarisa kuti masirindiri ako ari pamusoro pe0.5 MPa (70 psi)—pasi pekumanikidzwa uku, hunyoro uye tsvina zvinosangana mugasi.
Nheyo Yekupedzisira & Danho Rinotevera
Mutemo mukuru: Enzanisa gasi rako rekudzivirira nezvinhu zvako, enzanisa mhando nemutengo, uye gara uine chokwadi chekuti gasi rinounzwa rakachena uye rakakwana. Ita izvi nemazvo, uye simba rako rakasimbaWaya yeMIGichaita zvakanaka kwazvo.
Kana wangosarudza gasi rekudzivirira rakakodzera, kusarudza waya yeMIG yakasimba yepamusoro-soro inoenderana negasi nezvinhu zvako ndiyo danho rinotevera rekubudirira pakusanganisa. Waya yeMIG yakasimba yakanaka inoita kuti pave nekuumbwa kwemakemikoro kwakasimba uye kupatsanurwa kwewaya kwakatsetseka—ichishanda pamwe chete negasi rekudzivirira rakasarudzwa zvakanaka kuti ripe welds dzakasimba nguva dzese.
