Izindlela zokushisela ze-MIG Welding

2024-07-10

Gcina isandiso sentambo yokushisela engu-1/4 kuya ku-3/8 amayintshi (ubude bentambo yokushisela ephuma ekhanda lesibhamu esishiselayo).
Sebenzisa i-diameter encane yokushisela lapho ushisela amapuleti amancane; Lapho kushiswa amapuleti awugqinsi, kusetshenziswa izintambo ezinkulu zokushisela ezinobubanzi kanye nemishini yokushisela yamanje ephezulu.
Sebenzisa intambo yokushisela efanele ukushisela ucezu lokusebenza. Insimbi engagqwali welding wire welding insimbi engagqwali, aluminium welding wire welding aluminium, steel welding wire welding steel.
Sebenzisa igesi yokuvikela efanele. I-Carbon dioxide ifaneleka kakhulu ekushiseleni insimbi, kodwa uma isetshenziselwa ukushisela amapuleti amancane, izinga lokushisa lingase libe phezulu kakhulu. Ingxube ka-75% yegesi ye-argon kanye negesi ye-carbon dioxide engu-25% kufanele isetshenziselwe ukushisela izinto ezincane. I-aluminium yokushisela ingasebenzisa igesi ye-argon kuphela. Uma ushisela insimbi, ungasebenzisa futhi ingxube yamagesi amathathu (i-helium+argon+carbon dioxide).
Ukuze kuzuzwe ukulawula okungcono kakhulu kwe-weld bead, intambo yokushisela kufanele igcinwe iqondaniswe ngokuqondile nomphetho wokubopha we-melt pool.
Lapho umsebenzi wokushisela usesimweni esingavamile (ukushisela okuqondile, ukushisela okuvundlile, ukushisela phezulu), idamu elincane elincibilikisiwe kufanele ligcinwe ukuze kuzuzwe ukulawula okuphelele kobuhlalu bokushisela, futhi ucingo lokushisela oluncane kakhulu kufanele lusetshenziswe ngangokunokwenzeka.
Qinisekisa ukuthi usayizi wentambo yokushisela oyisebenzisayo ufana nombhobho, i-liner, kanye ne-drive roller.
Hlanza njalo i-welding gun liner futhi ushayele ama-roller ukuze uqinisekise ukuthi akukho-spatter emlonyeni wesibhamu sokushisela. Uma umlomo wesibhamu esishiselayo uvimbekile noma ukuphakelwa kocingo kungasheleli, buyisela esikhundleni.
Ngesikhathi sokushisela, zama ukugcina isibhamu sokushisela siqondile ukuze ugweme izinkinga zokuphakela ucingo.
Sebenzisa izandla zombili ngesikhathi esisodwa ngesikhathi sokushisela ukuze uqinisekise ukuzinza kwesibhamu sokushisela, futhi wenze lokho ngangokunokwenzeka. (Lokhu kuyasebenza nasekushiseleni i-electrode, i-TIG welding, nokusika i-plasma)
Lungisa ukucinana kwe-spool ye-welding wire spool kanye ne-roller eshayelayo yesiphakeli socingo ukuze kwanele nje ukuphakelwa kwezintambo, ngaphandle kokumpintshana kakhulu.
Uma ingasetshenziswa, gcina ucingo lokushisela endaweni ehlanzekile neyomile ukuze ugweme ukungcola okungase kuthinte umphumela wokushisela.
Sebenzisa i-DCEP reverse polarity power supply.
Ukudonsa (ukudonsa) isibhamu sokushisela kungafinyelela ukungena okujulile kanye nokushisela okuncane. Isu lokusunduza isibhamu lingafinyelela ukungena okungajulile kanye nama-weld seams abanzi.
