Izinzuzo kanye Nemibi Yomshini Wokushisela we-MAG
Ukushisela kwe-MAG (Metal Active Gas Welding) ubuchwepheshe obuvamile bokushisela nge-arc, obusetshenziswa kabanzi ekukhiqizeni ezimbonini, ukulungiswa kwezimoto, ukwakhiwa kwezakhiwo nezinye izindawo.
1. Isimiso Esiyisisekelo Sokushisela kwe-MAG
- Incazelo: Ukushisela kwe-MAG kusebenzisa igesi esebenzayo yokuvikela (njenge-CO₂ noma igesi exubile) njengendlela yokuvikela. Ucingo lokushisela kanye nensimbi eyisisekelo kuyancibilika nge-arc kagesi ukuze kufezeke ukuhlanganiswa kwensimbi.
- Umehluko ku-MIG: I-MIG (Metal Inert Gas Welding) isebenzisa igesi engasebenzi njenge-argon ne-helium, kanti i-MAG isebenzisa igesi esebenzayo efaka i-CO₂ eyimpuphu noma igesi exubile ye-Ar+CO₂. Igesi esebenzayo ibamba iqhaza ekuphenduleni kwe-metallurgical echibini elincibilikile, okwenza ilungele ukushisela insimbi yekhabhoni neyensimbi ephansi ye-alloy.
2. Ukwakheka Komshini Wokushisela we-MAG
- Ukunikezwa Amandla: Kuhlinzeka ngamanje we-DC noma we-pulsed ongaguquguquki.
- Ukuphakela Ucingo: Kuvikela ngokuzenzakalelayo ucingo oluqinile noma ucingo olune-flux.
- Isibhamu Sokushisela: Siyadlulisela ugesi futhi sihlinzeka ngegesi yokuvikela kanye nentambo yokushisela.
- I-Gas Cylinder & Regulator: Iphakela futhi ilawula ukuhamba kwegesi yokuvikela.
- Uhlelo Lokulawula: Lwenza kube lula ukulungisa izimo zokuhlanganisa ezifana ne-current, voltage kanye nesivinini sokudla wire.
3. Inqubo Yokusebenza
- Ukuqaliswa Komlilo: Kuveliswa umlilo kagesi phakathi kwentambo yokushisela nomsebenzi ukuze kwakheke ichibi elishisayo elincibilikile.
- Ukuvikela Ngesi: Igesi elisebenzayo liphuma kumphimbo wesibhamu ukuze kuhlanganiswe umoya futhi kuvinjelwe ukugqwala.
- Ukudluliswa Kwensimbi: Intambo yokushisela encibilikisiwe idluliselwa echibini elincibilikisiwe ngendlela yokudluliswa okufushane noma ukudluliswa okufafaziwe.
4. Izici Zokushisela Nge-MAG
Izinzuzo
- Ukusebenza kahle okuphezulu ngokudluliswa okuqhubekayo kwentambo, okufanele kukhiqizo oluzenzakalelayo.
- Ukuzivumelanisa nezimo okuqinile ezinhlobonhlobo zezinto ezihlanganisa insimbi yekhabhoni, insimbi engagqwali, nensimbi ye-alloy.
- Excellent welding quality with large penetration depth and controllable spatter, especially when using mixed gas.
- Izindleko zokusebenza eziphansi; igesi esebenzayo njenge-CO₂ ingabizi kakhulu kune-gesi engasebenzi.
Izinkinga
- Ithinteka emoyeni; ukusebenza kokuhlanganisa kudinga indawo engenamoya.
- Ukuvutha okunzima kakhulu uma kusetshenziswa igesi ye-CO₂ kuphela.
5. Izindawo Zokusebenzisa
- Ukukhiqiza: Ukushisela komzimba wezimoto nezingxenye zesakhiwo semishini.
- Ukwakhiwa: Ukushisela kwesakhiwo sensimbi, ibhuloho, nomapayipi.
- Ukuthuthwa kwemikhumbi & Imboni Enzima: Ukushisela kwemishini eqinile.
- Ukulungiswa: Ukushisela ukulungisa izinto zemishini nezimoto.
6. Ukukhethwa Kwegesi Lokuvikela
- Igesi le-CO₂ Eliyinhloko: Libiza kancane, lilungele ukushisela insimbi ye-carbon kodwa linomswakama omkhulu kancane.
- Igesi Elixubile (i-Ar+CO₂ 80/20 noma i-Ar+O₂): Kunciphisa umswakama futhi kuthuthukisa ukwakheka kwe-weld bead, kulungele ukushisela okuphezulu kwensimbi engagqwalisiwe namapuleti acwebezelayo.
7. Izinyathelo Zokuphepha Ekusebenzeni
- Gqoka isigqoko sokushisela namagilavu ukuze ugweme ukulimala komoya womlilo nokushisela okubabazekayo.
- Hlola ingcindezi yebhodlela legesi nokuhlanzeka kwegesi ngaphambi kokusebenza.
- Lungisa ugesi namandla kagesi ngokuvumelana nokujiya kwempahla nobubanzi bentambo.
- Hlanza uwoyela, umhlwa, nodaka ebusweni bendawo yokushisela ukuze ugweme izimbobo.
- Hlanza njalo umbhobho wesibhamu bese uhlola ipayipi lokudlulisa intambo ukuze kube ukugcinwa kwansuku zonke.
8. Izinkinga Ezijwayelekile Nezixazululo
- Izimbobo: Hlola ukugeleza komoya, ukuhlanzeka komoya, noma ukuhlanzeka kobuso bendawo yokushisela.
- Excessive Spatter: Match voltage and current parameters or switch to mixed shielding gas.
- I-Arc Engazinzile: Bheka ukuhamba kwe-wire okuhle nokuxhumana okuqinisekile kokuphuma.
- I-Wire Sticking: Thuthukisa isivinini sokudla wire noma ushintshe i-contact tip.
9. Iziphakamiso Zokukhetha Imodeli
- Uhlobo Lwendwangu: Sebenzisa i-CO₂ ehlanzekile noma i-Ar+CO₂ ye-carbon steel; khetha i-Ar+O₂ igesi ehlangene ye-stainless steel.
- Ubukhulu bokushisela: Ukudluliswa okufushane kwemishini emincane (0.6-3mm); ukudluliswa okufafazayo kwemishini eqinile.
- Isimo Sokusebenzisa: Amamodeli aphezulu kakhulu wokukhiqiza okuzenzakalelayo; imishini ephathekayo yokulungisa endaweni.
Isifinyezo
Ngokusebenza kahle kakhulu nokusebenza okuguquguqukayo, ukushisela kwe-MAG kube ubuchwepheshe obubodwa bokushisela obujwayelekile embonini yesimanje. Ukulawula umgomo wayo wokusebenza, ukukhethwa kwegesi namakhono okusebenza kungathuthukisa kakhulu ikhwalithi yokushisela nokusebenza kahle. Ekusebenziseni okusebenzayo, amapharamitha nokucushwa kwemishini kufanele kulungiswe ngokufanele ngokuya ngezici zezinto ezibonakalayo nezidingo zenqubo.
