Uma kukhulunywa nge-MIG yokushisela, kubalulekile ukuthi abashiseli abasha baqale ngezinto eziyisisekelo ukuze babeke isisekelo esiqinile sempumelelo. Inqubo ngokuvamile iyathethelela, okwenza kube lula ukufunda kune-TIG welding, isibonelo. Ingakwazi ukushisela izinsimbi eziningi futhi, njengenqubo yokuphakelwa ngokuqhubekayo, inikeza isivinini esikhulu nokusebenza kahle kunokushisela izinti.
Kanye nokuzijwayeza, ukwazi ulwazi oluthile olubalulekile kungasiza abashiseli abasha baqonde kangcono inqubo yokushisela ye-MIG
Ukuphepha kokushisela
Ukucatshangelwa kokuqala kwama-welders amasha ukuphepha kokushisela. Kubalulekile ukuthi ufunde futhi ulandele wonke amalebula kanye neManyuwali Yomnikazi wemishini ngokucophelela ngaphambi kokufaka, ukusebenzisa, noma ukusevisa okokusebenza kokushisela. Abashiselayo kufanele bagqoke isivikelo samehlo esifanele ukuze bagweme ukusha kwe-arc flash kanye nezinhlansi. Gqoka njalo izibuko zokuphepha kanye nesigqoko sokuzivikela esisethelwe ezingeni elifanele lomthunzi. Izimpahla zokuzivikela ezifanele zibalulekile futhi ukuze kuvikelwe isikhumba ekushayweni wugesi nasekushiseni. Lokhu kuhlanganisa:
· Izicathulo zesikhumba noma amabhuzu.
· Isikhumba noma amagilavu okushisela angashi
· Ijakhethi yokushisela engashi noma imikhono yokushisela
Ukungena komoya okwanele nakho kuyisici esibalulekile sokuphepha. Abashiseli kufanele ngaso sonke isikhathi bagcine ikhanda labo lingangeni lapho beshisela khona futhi baqiniseke ukuthi indawo abashisela kuyo inomoya owanele. Kungase kudingeke uhlobo oluthile lokukhipha intuthu. Izibhamu zokukhishwa kwefume ezisusa i-exhaust ku-arc nazo ziwusizo, futhi zisebenza kahle kakhulu uma ziqhathaniswa nokubanjwa phansi noma uphahla.
Izindlela zokudlulisa i-Welding
Ngokuya ngezinto eziyisisekelo kanye negesi yokuvikela, ama-welders angashisela ngezindlela ezihlukahlukene zokudlulisa ama-welding.
Isifunda esifushane sivamile ezintweni ezincanyana futhi sisebenza nge-voltage ephansi yokushisela kanye nesivinini sokuphakela kwezintambo, ngakho-ke kuhamba kancane kunezinye izinqubo. Iphinde ijwayele ukukhiqiza i-spatter edinga ukuhlanzwa kwe-post-weld, kodwa jikelele, kuyinqubo elula ukuyisebenzisa.
Ukudluliswa kweglobula kusebenza ngesivinini esiphezulu sokuphakela kwezintambo kanye nama-voltage wokushisela kunesekhethi emfushane futhi kusebenzela ukushisela ngentambo ene-flux-cored eno-100% we-carbon dioxide (CO2) (bona imininingwane ku-CO2 esigabeni esilandelayo). Ingasetshenziswa ezintweni eziyisisekelo ezingu-1/8-intshi neziwugqinsi. Njengokushisela i-MIG yesifunda esifushane, le modi ikhiqiza i-spatter, kodwa iyinqubo esheshayo.
Ukudluliswa kwesifutho kunikeza i-arc ebushelelezi, ezinzile, okuyenza ihehe kumashiseli amaningi amasha. Isebenza kuma-welding amperages aphezulu kanye ne-voltage, ngakho iyashesha futhi ikhiqiza. Isebenza kahle ezintweni eziyisisekelo eziyi-1/8 intshi noma ngaphezulu.
Igesi yokuvikela i-Welding
Ngaphezu kokuvikela i-weld pool emkhathini, uhlobo lwegesi evikelayo esetshenziselwa ukushisela i-MIG lunomthelela ekusebenzeni. Ukungena kwe-weld, ukuzinza kwe-arc kanye nezakhiwo zemishini kuncike ekuvikeleni igesi.
I-Straight carbon dioxide (CO2) inikezela ngokungena kwe-weld ejulile kodwa ine-arc engaqinile kanye ne-spatter eyengeziwe. Isetshenziselwa ukushisela i-MIG yesifunda esifushane. Ukwengeza i-argon kwingxube ye-CO2 kuvumela ukusetshenziswa kokudluliswa kwesifutho ukuze kukhiqizwe kakhulu. Ibhalansi ye-75% argon kanye ne-25% ijwayelekile.
Ngale kwezisekelo
Kanye nokuzijwayeza, ukwazi ulwazi oluthile olubalulekile kungasiza abashiseli abasha baqonde kangcono inqubo yokushisela ye-MIG. Kubalulekile futhi ukujwayelana nezinto zokusebenza, okuhlanganisa izibhamu zokushisela ze-MIG namalayini wokushisela. Ukuqonda ukuthi ungakhetha futhi ulondoloze kanjani le mishini kungafinyelela kude ekusunguleni ukusebenza okuhle kokushisela, ikhwalithi nokukhiqiza.
