Spot welding ke mokhoa o sebelisoang haholo ho kopanya liindasteri tsa tlhahiso, ho kenyeletsoa mafapha a likoloi le a sefofane.Mechineng ea welding ea maqhubu a mahareng, khanyetso ea welding e bapala karolo ea bohlokoa ho lekanyeng boleng le ts'epahalo ea weld.Sengoliloeng sena se hlahloba khanyetso e amehang ho cheselleng letheba le bohlokoa ba eona ho fihlela li-welds tse atlehileng.
Tlhaloso ea ho hanyetsa ha ho tjheseletsa sebakeng:
Resistance in spot welding e bolela khanyetso eo motlakase o kopanang le eona ha o ntse o feta har'a lisebelisoa tse kopantsoeng.Ho hanyetsa ho susumetsoa ke lintlha tse fapaneng, ho kenyelletsa thepa ea thepa, maemo a holim'a metsi, moralo oa li-electrode, le khanyetso ea ho kopana pakeng tsa li-electrode le li-workpieces.
Lintlha tse amang khanyetso ho welding ea matheba:
Thepa ea thepa: Lisebelisoa tse fapaneng li bonts'a conductivity e fapaneng ea motlakase, e amang khanyetso ea bona ho phallo ea motlakase nakong ea welding.Lisebelisoa tse nang le matla a phahameng a ho hanyetsa motlakase, joalo ka tšepe e sa hloekang, hangata li na le khanyetso e phahameng ha li bapisoa le lisebelisoa tse kang koporo kapa aluminium.
Maemo a holim'a metsi: Bohloeki le boemo ba bokaholimo ba lisebelisoa tsa mosebetsi li ama haholo ho hokahanngoa ha motlakase, ka lebaka leo, ho hanyetsa nakong ea tjheseletsa.Oxidation, litlolo, kapa litšila holim'a libaka tsa mosebetsi li ka eketsa khanyetso le ho sitisa ho thehoa ha weld e matla.
Moralo oa elektrode: Moralo le sebopeho sa li-electrode li susumetsa sebaka sa ho ikopanya le khatello e sebelisoang ho li-workpieces.Moralo o nepahetseng oa li-electrode o netefatsa phetisetso e sebetsang ea hajoale le ho fokotsa khanyetso ho sebopeho sa li-electrode-workpiece.
Ikopanye le khanyetso: Ho hanyetsa ho kopana pakeng tsa li-electrode le li-workpieces ho ama khanyetso e akaretsang ea ts'ebetso ea welding ea letheba.Ho bohlokoa ho theha khokahano e ntle ea motlakase lipakeng tsa li-electrode le li-workpieces ho fokotsa khanyetso le ho tsamaisa phallo e sebetsang ea hajoale.
Bohlokoa ba ho laola ho hanyetsa ha li-welding:
Ho laola ho hanyetsa ha ho cheselletsa sebakeng ho bohlokoa bakeng sa ho fumana li-welds tse tsitsitseng le tsa boleng bo holimo.Ho hanyetsa ho ama ka ho toba moloko oa mocheso, sebopeho sa nugget, le matla a kakaretso a weld.Ho hanyetsa ka mokhoa o nepahetseng ho tiisa mocheso o lekaneng oa mocheso ho qhibilihisa libaka tsa mosebetsi le ho theha bond e matla ea metallurgical.Ho kheloha ho hanyetsang ho ka fella ka ho se kopane ha weld, manonyeletso a fokolang, kapa esita le tšenyo ea electrode.
Mechineng ea welding ea maqhubu a mahareng, khanyetso e amehang ts'ebetsong ea welding e bapala karolo ea bohlokoa ts'ebetsong ea welding.Ho utloisisa lintlha tse susumetsang khanyetso le ho e laola ka har'a mefuta e lakatsehang ho bohlokoa bakeng sa ho hlahisa li-welds tse tšepahalang le tse tšoarellang.Ka ho ntlafatsa khetho ea thepa, ho boloka libaka tse hloekileng tsa li-workpiece, ho rala li-electrode tse nepahetseng, le ho etsa bonnete ba hore li-electrode-to-workpiece li kopana hantle, basebetsi ba ka khona ho laola khanyetso le ho finyella li-welds tse atlehileng ka boleng le tshebetso e lakatsehang.
