Resistance spot welding ke mokhoa o sebelisoang haholo lits'ebetsong tsa tlhahiso, haholo indastering ea likoloi le lifofane. Mokhoa ona o kenyelletsa ho kopanya likotoana tse peli tsa tšepe hammoho ka ho sebelisa mocheso le khatello ka li-electrode. Ntho e 'ngoe ea bohlokoa ka ho fetisisa ts'ebetsong ena ke khatello ea electrode. Sehloohong sena, re tla hlahloba bohlokoa ba khatello ea elektrode mochining oa ho tjheseletsa letheba le phello ea eona ho boleng ba li-welds.
Ho utloisisa Khatello ea Electrode
Electrode pressure, eo hape e tsejoang e le welding force or contact pressure, e bolela matla a sebelisoang ke li-electrode tsa welding holim'a lisebelisoa tse kopantsoeng. Khatello ena e bapala karolo ea bohlokoa ho netefatsa hore ho na le weld e atlehileng. Mesebetsi ea mantlha ea khatello ea electrode ke:
1. Ho netefatsa Tšebeliso e Ntle ea Motlakase
Bakeng sa ho tjheseletsa ha letheba le sebetsang hantle, ho tlameha ho be le tsela e tlase ea motlakase pakeng tsa li-electrode le li-workpieces. Khatello e lekaneng e tiisa ho kopana ha motlakase hantle, ho fokotsa ho hanyetsa motlakase le ho etsa hore ho phalla ha hona joale ho tjheseletsa ka motsoako. Sena, ka lehlakoreng le leng, se thusa ho hlahisa mocheso o hlokahalang bakeng sa ts'ebetso ea ho cheselletsa.
2. Ho Khothalletsa Phetoho ea Lintho
Khatello e hlahisoang ke li-electrode e etsa hore ho be le deformation sebakeng sa thepa ea workpiece. Deformation ena e theha kamano e haufi-ufi pakeng tsa lisebelisoa tse peli tsa mosebetsi, ho matlafatsa tlamo ea metallurgic nakong ea ho cheselletsa. E boetse e thusa ho phunyeletsa litšila tse holim'a metsi tse kang li-oxide le li-coatings, ho ntlafatsa boleng ba weld.
3. Ho Laola Moloko oa Mocheso
Khatello e nepahetseng ea li-electrode e thusa ho laola boholo ba mocheso o hlahisoang nakong ea welding. Khatello e feteletseng e ka lebisa mocheso o feteletseng, ha khatello e sa lekaneng e ka fella ka tlhahiso e sa lekaneng ea mocheso. Ho fihlella tekano e nepahetseng ho bohlokoa ho thibela tšenyo ea li-workpieces le ho netefatsa weld e matla.
Khatello e Ntle ea Electrode
Ho fumana khatello e nepahetseng ea elektrode ho ipapisitse le lintlha tse fapaneng, ho kenyelletsa le thepa e cheselitsoeng, botenya ba eona, le hona joale. Hangata bahlahisi ba fana ka tataiso le litlhaloso bakeng sa khatello ea li-electrode ho latela lintlha tsena. Ho feta moo, li-weld operators li ka lekola le ho fetola khatello ea li-electrode ho fihlela boleng bo lakatsehang ba weld.
Tšusumetso ho Boleng ba Weld
Khatello e sa lekaneng ea li-electrode e ka lebisa ho liphoso tse 'maloa tsa welding, joalo ka fusion e sa fellang, porosity, le li-weld bond tse fokolang. Ka lehlakoreng le leng, khatello e feteletseng e ka fella ka ho tjheseletsa ho feteletseng, ho baka deformation le ho senya lisebelisoa tsa mosebetsi. Ka hona, ho boloka khatello e nepahetseng ea li-electrode ho bohlokoa bakeng sa ho hlahisa li-welds tsa boleng bo holimo tse nang le thepa e lakatsehang ea mochini.
Mechineng ea ho tjheseletsa sebakeng sa ho hanyetsa, khatello ea elektrode ke paramente ea bohlokoa e amang boleng ba li-welds haholo. E etsa bonnete ba ho kopana ha motlakase hantle, e khothalletsa ho senyeha ha thepa, le ho laola tlhahiso ea mocheso. Ho fumana liphetho tse nepahetseng, ho bohlokoa ho utloisisa lisebelisoa tse cheselitsoeng le ho latela tataiso e khothaletsoang ea khatello ea li-electrode. Taolo e nepahetseng ea khatello ea li-electrode e ke ke ea ntlafatsa boleng ba weld feela, empa hape e tla kenya letsoho ho sebetsa hantle le ho ts'epahala ha ts'ebetso ea welding.
