Lisosa tsa Electrode Sticking Phenomenon in Medium-Frequency Inverter Spot Welding of Galvanized Steel Sheets?

Lishiti tsa tšepe tse entsoeng ka galvanized li sebelisoa hangata liindastering tse fapaneng ka lebaka la ho hanyetsa ha tsona ho hoholo ha kutu. Leha ho le joalo, ha tjheseletsa tšepe galvanized sebelisa seaplane maqhubu inverter letheba tjheseletsa mochini, ho ka etsahala ntho e tsejoang e le electrode sticking. Sehlooho sena se ikemiseditse ho hlahloba lisosa tsa li-electrode sticking inverter spot welding of galvanized sheets sheets le ho fana ka leseli mabapi le mokhoa oa ho fokotsa taba ena.

1. Mouoane oa Zinc le Tšilafalo: E 'ngoe ea lisosa tse ka sehloohong tsa ho khomarela li-electrode ho tjheseletsa maqephe a tšepe a masenke ke ho lokolloa ha mouoane oa zinki nakong ea ts'ebetso ea ho cheselletsa. Lithempereichara tse phahameng tse hlahisoang nakong ea welding li ka etsa mouoane oa coat ea zinki, e ntan'o kopanya le ho khomarela libaka tsa electrode. Tšilafalo ena ea zinki e etsa lera le etsang hore li-electrode li khomarele mosebetsi, e leng se lebisang mathateng a karohano ea li-electrode.
2. Sebopeho sa Zinc Oxide: Ha mouoane oa zinki o lokolloa nakong ea welding o arabela ka oksijene ea sepakapaka, o etsa zinc oxide. Ho ba teng ha zinki oxide holim'a li-electrode ho mpefatsa taba ea ho khomarela. Zinc oxide e na le thepa ea sekhomaretsi, e tlatsetsang ho khomarela pakeng tsa electrode le letlapa la tšepe.
3. Lisebelisoa tsa Electrode le Coating: Khetho ea thepa ea elektrode le ho roala e ka boela ea ama ketsahalo ea ho khomarela li-electrode. Lisebelisoa tse ling tsa li-electrode kapa liaparo li ka ba le kamano e phahameng ea zinki, e leng ho eketsang monyetla oa ho khomarela. Ka mohlala, li-electrode tse nang le motsoako oa koporo li atisa ho khomarela ka lebaka la kamano ea tsona e phahameng bakeng sa zinki.
4. Pholiso e sa lekaneng ea Electrode: Pholiso e sa lekaneng ea li-electrode e ka kenya letsoho ho khomarelang li-electrode. Ts'ebetso ea welding e hlahisa mocheso o moholo, 'me ntle le mekhoa e nepahetseng ea ho pholisa, li-electrode li ka chesa haholo. Mocheso o phahameng o khothalletsa ho khomarela mouoane oa zinki le zinki oxide holim'a libaka tsa electrode, e leng se fellang ka ho khomarela.

Maano a ho Fokotsa: Ho fokotsa kapa ho thibela ho khomarela li-electrode ha ho tjhesetsoa lishiti tsa tšepe tse nang le mochini o tjheseletsang sebaka sa maqhubu a mahareng, ho ka sebelisoa maano a 'maloa:

1. Ho apara Electrode: Ho apara kamehla ho bohlokoa ho tlosa zinki le ho boloka libaka tse hloekileng tsa electrode. Tlhokomelo e nepahetseng ea li-electrode e thusa ho thibela ho bokellana ha mouoane oa zinki le zinc oxide, ho fokotsa ketsahalo ea ho khomarela.
2. Electrode Coating Selection: Ho khetha liaparo tsa elektrode tse nang le kamano e tlase bakeng sa zinki ho ka thusa ho fokotsa ho khomarela. Liaparo tse nang le thepa e khahlanong le lithupa kapa liphahlo tse etselitsoeng ka ho khetheha bakeng sa ho cheselletsa tšepe ea galvanized li ka nahanoa.
3. Pholiso e Lekaneng: Ho bohlokoa ho etsa bonnete ba hore li-electrode li pholile ka ho lekaneng nakong ea welding. Mekhoa e nepahetseng ea ho pholisa, e kang ho pholisa metsi, e ka felisa mocheso ka katleho le ho thibela ho phahama ho feteletseng ha mocheso oa li-electrode, ho fokotsa monyetla oa ho khomarela.
4. Ntlafatso ea Liparamente tsa Welding: Mekhahlelo ea ho tjheseletsa hantle, joalo ka ea hajoale, nako ea ho cheselletsa, le matla a elektrode, e ka thusa ho fokotsa ho khomarela. Ka ho fumana litlhophiso tse nepahetseng tsa paramente, ts'ebetso ea welding e ka ntlafatsoa ho fokotsa mouoane oa zinki le ho khomarela.

Ho ba teng ha li-electrode tse khomarelang ka har'a tjheseletsa ea li-inverter tse mahareng tsa lishiti tse entsoeng ka masenke ho bakoa haholo ke ho lokolloa ha mouoane oa zinki, ho thehoa ha zinki oxide, lisebelisoa tsa elektrode le mabaka a ho roala, le pholiso e sa lekaneng ea li-electrode. Ka ho kenya ts'ebetsong maqheka a kang ho roala li-electrode kamehla, ho khetha liphahlo tse loketseng tsa li-electrode, ho netefatsa hore ho na le pholiso e lekaneng, le ho ntlafatsa li-parameter tsa welding, taba ea ho khomarela e ka fokotsoa. Mehato ena e tla kenya letsoho ts'ebetsong ea litšepe tse thellang, tlhahiso e ntlafetseng, le litšepe tsa boleng bo holimo ha ho sebetsa ka masenke a masenke.
