Izintambo ze-MIG zidlala indima ebalulekile ekushiseni kwesimanje. Ukuze sithole imiphumela yokushisisa esezingeni eliphezulu, sidinga ukwazi ukuthi singakhetha futhi sisebenzise kanjani izintambo ze-MIG ngendlela efanele.
Ungayikhetha kanjani intambo ye-MIG?
Okokuqala, sidinga ukususelwa ezintweni eziyisisekelo, izinhlobo ezahlukene zezinto eziyisisekelo zinquma indlela yokukhetha ucingo. Izinto eziyisisekelo ezivamile yinsimbi yekhabhoni, insimbi engagqwali, i-aluminium alloy nokunye. Ngensimbi yekhabhoni, ukukhethwa kweucingo lokushiselakufanele isekelwe ezingeni layo lamandla. Insimbi yekhabhoni enamandla aphansi ingakhetha ucingo olujwayelekile lokushisela insimbi yekhabhoni, kuyilapho insimbi yekhabhoni enamandla aphezulu idinga ucingo olunamandla aphezulu ukuqinisekisa ukusebenza kahle ngemva kokushisela. Kunezinhlobo eziningi zensimbi engagqwali, okuhlanganisa insimbi engagqwali ye-austenitic, insimbi engagqwali ye-ferritic, insimbi engagqwali ye-martensitic njalo njalo. Ibanga ngalinye lensimbi engagqwali linokwakheka kwamakhemikhali alo ahlukile kanye nezici zokusebenza, ngakho-ke udinga ukukhetha ucingo lwensimbi engagqwali olufanelana nalo, ukuze uqinisekise ukuthi ukumelana nokugqwala kanye nezakhiwo zemishini ze-weld kuhambisana nezinto eziyinhloko.
Yiqiniso, izidingo zokusebenza kokushisela esinazo emkhakheni wokucatshangelwa, izidingo zamandla okushisela zingenye yezisekelo ezibalulekile zokukhetha ucingo. Uma ukushisela kudinga ukumelana nemithwalo ephezulu, khona-ke ucingo olunamandla aphezulu kufanele lukhethwe. Lokhu kuqinisekisa ukuthi ijoyinti elishiselwe ngeke liphuke ngesikhathi sokusetshenziswa. Ukuze kushiselwe ngezidingo zokumelana nokugqwala, njengezinto zokusebenza ezisetshenziswa ezindaweni ezinzima njengemboni yamakhemikhali nolwandle, kuyadingeka ukukhetha izintambo zokushisela ezinokumelana nokugqwala okuhambisanayo. Uma umsebenzi wokushisela udinga ukuqina okuhle noma ukusebenza kahle kwezinga lokushisa eliphansi, udinga futhi ukukhetha ucingo olufanele ngokucophelela ukuze uhlangabezane nalezi zidingo ezikhethekile.
Okwesibili, sidinga ukunquma ububanzi bentambo. Ukukhetha ububanzi bentambo kanye nogesi wamanje, isikhundla sokushisela kanye nobukhulu bezinto eziyisisekelo kuhlobene kakhulu. Ngokuvamile, umshini wokushisela omkhulu kanye nogesi wesisekelo obanzi kudinga ukusetshenziswa kogesi obanzi. Lokhu kungenxa yokuthi izintambo ezibanzi zingamelana nemisinga ephezulu futhi zinikeze insimbi eyengeziwe yokugcwalisa ukuqinisekisa amandla ensimbi. Uma kuqhathaniswa nokushisela ipuleti elincane, izintambo ezincane zobubanzi zivame ukukhethwa ukuze kuncishiswe ukufakwa kokushisa kokushisela futhi kuvinjelwe ukushiswa kanye nokuphambuka. Ezikhundleni ezahlukene zokushisela, kuyadingeka futhi ukukhetha ububanzi obufanele bentambo yokushisela. Isibonelo, endaweni yokushisela ephezulu, ngenxa yobunzima bokusebenza, ukuze kube lula ukusebenza nokuqinisekisa ikhwalithi yokushisela, kufanele ukhethe ucingo oluncane.
Ngaphezu kwalokhu, sidinga ukuhlanganisa amapharamitha enqubo yokushisela ekukhetheni ucingo, amapharamitha enqubo yokushisela e-MIG ahlukene, njengogesi wamanje, i-voltage, isivinini sokushisela, njll., nawo anomthelela obalulekile ekukhetheni ucingo. Kufanele kusekelwe kumapharamitha enqubo yokushisela yangempela ukuze kukhethwe ucingo olungazivumelanisa nalezi pharamitha. Endabeni yokushisela yamanje ephezulu kanye nesivinini esikhulu, kubalulekile ukuqinisekisa ukuthi ucingo lungancibilika ngokulinganayo futhi lwakhe i-weld esezingeni eliphezulu enqubweni yokushisela yesivinini esikhulu. Kubalulekile ukukhetha ucingo lokushisela olunezakhiwo ezinhle zokubeka kanye nokuqina.
Ngesikhathi esifanayo, sidinga futhi ukucabangela ukuzinza kokunikezwa kwentambo kanye nensizakalo yangemva kokuthengisa. Khetha uhlobo lwentambo olunedumela elihle kanye neziteshi zokunikeza ezithembekile ukuqinisekisa ukuthi ngeke kube nokushoda kwentambo enqubweni yokushisela. I-TANKII Alloy inezinhlobo eziningi zezintambo zokushisela ezinekhwalithi ezinzile, uma uzidinga, sicela usithinte.
Ngakho-ke yiziphi izinyathelo zokuphepha zokusebenzisaUcingo lokushisela lwe-MIG?
Into yokuqala okufanele uyisho ukuthi maqondana nemishini, kubalulekile ukukhetha umshini wokushisela ofanele ukushisela i-MIG. Ukusebenza komshini wokushisela kufanele kuzinzile, futhi amandla okukhipha kanye ne-voltage kufanele kube nembambo enembile. Ngesikhathi esifanayo, qiniseka ukuthi umshini wokushisela uqinile ukuze uvimbele ukushayiswa ugesi. Ukusebenza okuvamile kohlelo lokuphakelwa kwentambo kuyisihluthulelo sokuqinisekisa ikhwalithi yokushisela. Indlela yokuphakelwa kwentambo kufanele isebenze kahle futhi ingcindezi yesondo lokuphakelwa kwentambo kufanele ibe phakathi ukuze kugwenywe ukuphakelwa kwentambo okungazinzile noma ukushelela kwentambo. Ngaphezu kwalokho, ipayipi lokuphakelwa kwentambo kufanele lihlanzwe njalo ukuze kuvinjelwe ukuvaleka.
Ukukhetha igesi evikelayo nakho kubalulekile. Amagesi avikelayo avamile yi-argon, i-helium noma ingxube yawo. Qiniseka ukuthi ubumsulwa begesi evikelayo buhlangabezana nezidingo zokuqinisekisa ikhwalithi yokushisela. Ukulungiswa okunengqondo kokugeleza kwegesi evikelayo kubaluleke kakhulu. Ngokuvamile, ukugeleza kwegesi kufanele kulungiswe ngokuya ngogesi wokushisela, ububanzi bentambo kanye nendawo yokushisela kanye nezinye izinto. Ngaphezu kwalokho inqubo yokushisela, ukuqinisekisa ukuvikelwa okuhle kwegesi endaweni yokushisela, ukugwema ukungena komoya echibini elincibilikisiwe.
Kufanele kuqashelwe ukuthi ngokuvamile sikhetha ucingo lwe-MIG olufanele ngokwezinto zokwakha, ukujiya kanye nezidingo zokushisela zento eyisisekelo. Ububanzi, ukwakheka kwamakhemikhali kanye nezakhiwo zemishini zentambo yokushisela kufanele zifane nezinto eziyisisekelo. Kufanele sihlole ikhwalithi yobuso bentambo yokushisela ngaphambi kokusebenzisa, futhi siyihlanze uma kukhona ukugqwala namafutha. Lawula ubude bokunwetshwa kwentambo yokushisela. Ngokuvamile, ubude bentambo buphindwe kayishumi kunobubanzi bentambo obufanele. Ukwelula ubude obude kakhulu kuzoholela ekumelaneni okukhulu, ukuze ucingo lushise ngokweqile, kuthinte ikhwalithi yokushisela.
Ngaphezu kwalokho, izikhundla ezahlukene zokushisela zinezidingo ezahlukene zenqubo yokushisela. Ekushiseni okusicaba, ekushiseni okuqondile, ekushiseni okuvundlile kanye nasemuva, kufanele kulungiswe amapharamitha okushisela kanye nezindlela zokusebenza ukuqinisekisa ikhwalithi yokushisela. Ukuze kushiswe ezinye izinto ezifana namapuleti amakhulu noma insimbi enekhabhoni ephezulu, kungadingeka ukushisisa kusengaphambili ukuze kuvinjelwe ukuqhekeka. Ngesikhathi esifanayo, izinga lokushisa eliphakathi kwezingqimba kufanele lilawulwe ukuze kugwenywe ukuphakama kakhulu noma phansi kakhulu. Ngesikhathi senqubo yokushisela, i-slag kanye ne-splatter ebusweni be-weld kufanele kuhlanzwe ngesikhathi ukuqinisekisa ikhwalithi yokubukeka kwe-weld kanye nenqubekela phambili ebushelelezi yokushisela okulandelayo.
