Ukukhetha igesi yokuvikela engafanele kungakushiya unezimbobo ezigcwele ama-porosity, ama-spatter, noma amandla abuthakathaka—ngisho noma usebenzisa ucingo oluqinile lwe-MIG kanye nemishini. Igesi yokuvikela ye-MIG ingase ibonakale ingabonakali, kodwa "yifomula yokhiye engabonakali" ethinta ngqo izici ze-arc, izindlela zokudlulisa insimbi, kanye nezakhiwo zokugcina zemishini ye-weld. Ngezansi, sizohlukanisa uhlaka olulula lwesinqumo ukukusiza ukhethe igesi yokuvikela efanele isicelo sakho.
Uhlaka Lwezinqumo: Thola Igesi Yakho Ephelele Yokuvikela
Sizoxoxa ngemibuzo emithathu eyinhloko ukuze sinciphise izinketho zakho. Akusekho ukuqagela—kukhona ukukhetha okuqondiwe okusekelwe ezidingweni zakho zangempela.
Umbuzo 1: Ushisela Izinto Ezinjani?
Izinto zokwakha ziyisici sokuqala nesibaluleke kakhulu. Ake siqale ngezinto ezivame kakhulu bese sidlulela ezintweni ezikhethekile.
Insimbi Ethambile (Isimo Esivame Kakhulu)
Ngegesi yokushisela insimbi ethambile ngentambo eqinile ye-MIG, kunezinketho ezimbili ezivelele emakethe. Nansi indlela ezihlanganiswa ngayo:
Igesi le-C25 (75% Ar, 25% CO2) – Ukukhetha Okuyinhloko Komhlaba Wonke
Kungani isebenza: Le ngxube ye-argon CO2 inikeza i-arc ezinzile, i-welding spatter encane, kanye nokubukeka kwe-weld okubushelelezi—ukuxazulula izinkinga ezinkulu ze-welding yensimbi emnene. Inciphisa ukulahleka kwe-alloy element, ikhulisa amandla okuthambekela kwe-weld, futhi isebenza ezinhlelweni eziningi, kusukela kumashidi amancane kuya kumapuleti anobukhulu obuphakathi. Kungakhathaliseki ukuthi wenza i-short-circuit noma i-spray transfer, i-C25 igcina inqubo ihlanzekile futhi ilawuleka.C25
Okuhle kakhulu: Imisebenzi eminingi yensimbi ethambile lapho ikhwalithi, ukubukeka, kanye nokulula kokusebenza kubalulekile.
I-CO2 Emsulwa - Ukuhweba Okungazindleko
Kungani isetshenziswa: I-CO2 emsulwa ishibhile kakhulu kunegesi exubile, okwenza ikhange emisebenzini eningi kakhulu ngesabelomali esincane. Iphinde inikeze ukungena okujulile, okuwusizo ekushiseni amapuleti amakhulu ngaphandle kokucwebezela. Ukushintshana: Lindela i-arc "enzima", ukuchitheka okuningi kokushisisa, kanye nendawo yokushisisa eqinile. Uzochitha isikhathi esengeziwe ekuhlanzeni ngemva kokushisisa, futhi ukulahlekelwa yi-alloy kuphakeme uma kuqhathaniswa ne-C25.
Okuhle kakhulu: Insimbi ethambile ejiyile lapho ukubukeka kwayo kungabalulekile khona futhi izindleko ziyinto eza kuqala.
Icebiso lochwepheshe: Uma ushisela insimbi ethambile futhi ufuna inqubo ehlanzekile, engenazinkinga, qala nge-C25. Kuyindlela eguquguqukayo kakhulu yokusetshenziswa kwezintambo ze-MIG eziqinile.
Insimbi engagqwali
Igesi yokushisela yensimbi engagqwali idinga ukugcina ukumelana nokugqwala nokuqinisekisa ukubukeka okuhle kokushisela. I-argon emsulwa ngeke isebenze lapha—iholela ekumanzisweni kabi kokushisela kanye nokungcoliswa.成形Khetha igesi exutshwe kathathu njenge-Ar + 2-5% CO2 + 1-2% O2 noma i-Ar + 90% He + 2.5% CO2. Lokhu kuhlanganisa kunciphisa ukucindezelwa kobuso bensimbi encibilikisiwe, kuthuthukisa ukusabalala kwe-weld, futhi kunciphise ukulahleka kwe-alloy, kugcina izakhiwo zokuvikela zensimbi engagqwali ziphelele.
I-Aluminium
I-Aluminium idinga i-argon emsulwa noma ingxube ye-argon-helium. Umsebenzi oyinhloko we-Argon ukuhlanza ifilimu ye-aluminium oxide (okuyinto edingekayo kuma-weld aqinile) nokuqinisa i-arc. Ukwengeza i-helium kukhulisa ukufakwa kokushisa, okusiza ngezingxenye ze-aluminium ezijiyile ngokwandisa ukungena kanye nesivinini sokushisela. Gwema noma iyiphi i-CO2 noma i-O2 kugesi yokuvikela i-aluminium—izobangela ukugoba kanye nama-weld aqhekekile.
Umbuzo 2: Yiziphi Izakhiwo Zokushisela Ozibeka Eqhulwini?
Ukukhetha kwakho igesi kuthinta ngqo indlela i-weld yakho ebukeka futhi isebenza ngayo. Qondanisa igesi nezakhiwo zakho eziza kuqala:
- Udinga ubuhlalu obubanzi bokushisela kanye nokungena okujulile (kuhle kakhulu kumashidi amancane)? Sebenzisa isilinganiso esiphezulu se-argon - ithambisa i-arc futhi ivimbele ukusha.
- Udinga ukungena okujulile ukuze uthole amapuleti aminyene? I-CO2 emsulwa noma ingxube ye-CO2 ephezulu iletha ukushisa okugxilile.
- Ufuna isivinini sokushisela esisheshayo? Izingxube ze-Argon-helium noma i-C25 zivumela i-amperage ephezulu ngaphandle kokuchitheka ngokweqile, okukhulisa umkhiqizo.
- Uyakuzonda ukuhlanzwa ngemva kokushiswa? I-C25 noma ezinye izingxube ezicebile nge-argon zinciphisa kakhulu ukuchitheka kokushiswa, zikongela isikhathi sokugaya nokuqeda.
Umbuzo 3: Isabelomali Sakho Singakanani?
Masibe ngokoqobo—isabelomali siqhuba izinqumo eziningi. Nansi indlela yangempela yokuhlukanisa izindleko, ngale kwentengo kaphethiloli kuphela:
- I-CO2 Emsulwa: Izindleko zikaphethiloli eziphansi kakhulu kusengaphambili, kodwa izindleko zesikhathi eside eziphakeme ngenxa yesikhathi esengeziwe sokuhlanza kanye nokwanda kwemfucuza yezintambo ze-MIG eqinile.
- Igesi le-C25: Izindleko zegesi ziphezulu kune-CO2 emsulwa, kodwa izindleko zizonke ziphansi ngenxa yesivinini sokushisela esisheshayo kanye nokulungiswa okuncane. Akukho mishini eyengeziwe edingekayo—isilinda esisodwa nje sokuxuba.
- Izingxube ze-tri-mix noma ze-argon-helium: Izindleko eziphezulu zezinto ezikhethekile, kodwa ziyadingeka ukuze kugwenywe ukwehluleka okubizayo kokushisela.
Nasi isivumelwano: Uma unesabelomali esincane kodwa ushise insimbi ethambile eningi, i-CO2 emsulwa ingenzeka—cabanga nje ngesikhathi sokuhlanza. Ezitolo eziningi, i-C25 inikeza ibhalansi engcono kakhulu yezindleko nokusebenza.
Amathiphu Abalulekile: Ungalimazi Ukukhetha Okuhle Kwegesi Ngokusethwa Okubi
Ngisho negesi yokuvikela efanele ngeke isindise ukushisela kwakho uma uphazamisa izinga lokugeleza kwegesi noma ukoma kwegesi. Le mininingwane ayinakuxoxiswana ngayo:
Izinga Lokugeleza Kwegesi (CFH/LPM)
Ukugeleza okuncane kakhulu kushiya i-weld yakho ingavikelekile (kubangela ukugoba kwe-weld); okuningi kakhulu kudala ukuxokozela (kumunca umoya, futhi kubangele ukugoba). Eziningi zezinhlelo zokusebenza ze-MIG wire eqinile:
- Insimbi ethambile (C25 noma i-CO2 emsulwa): 15-25 LPM (30-50 CFH)
- Insimbi engagqwali (ingxube emithathu): 18-28 LPM (38-60 CFH)
- I-Aluminium (i-argon/i-argon-helium): 20-30 LPM (42-63 CFH)
Ukomisa kwegesi
Umswakama kugesi ovikelayo ungumbulali othule. Ubangela ukugoba kwe-weld futhi ubuthakathaka ama-weld. Sebenzisa njalo umshini wokomisa/wokuhlunga emgqeni wakho wegesi, futhi uhlole ukuthi amasilinda akho angaphezu kuka-0.5 MPa (70 psi)—ngaphansi kwalokhu kucindezela, umswakama kanye nokungcola kugxilile kugesi.
Isimiso Sokugcina Nesinyathelo Esilandelayo
Umthetho oyinhloko: Qondanisa igesi yakho yokuvikela nezinto zakho, bhalansisa ikhwalithi nezindleko, futhi njalo uqinisekise ukulethwa kwegesi okuhlanzekile nokwanele. Yenza lokhu kube okulungile, kanye nokuqina kwakhoIntambo ye-MIGizosebenza kahle kakhulu.
Uma usukhethe igesi yokuvikela efanele, ukukhetha intambo eqinile ye-MIG esezingeni eliphezulu efanelana negesi kanye nezinto zakho kuyisinyathelo esilandelayo sempumelelo yokushisela. Intambo eqinile ye-MIG enhle iqinisekisa ukwakheka kwamakhemikhali okuzinzile kanye nokufakwa kwentambo okubushelelezi—isebenza ngokuvumelana negesi yakho yokuvikela ekhethwe ngokucophelela ukuze ilethe ukushisela okuqinile nokuqhubekayo njalo.
