Resistance spot welding ke mokhoa o sebelisoang haholo mekhoeng ea ho etsa le ea kaho. E kenyelletsa ho kopanngoa ha lishiti tse peli kapa ho feta tsa tšepe ka ho sebelisa khatello le motlakase ho etsa weld. Likarolo tse hlahisoang tsa welding li bonts'a litšobotsi tse 'maloa tse ikhethang tse bohlokoa ho utloisisa boleng le bots'epehi ba weld. Sehloohong sena, re tla hlahloba lintlha tse ka sehloohong tsa ho tjheseletsa manonyeletso a hlahisoang ke mechini ea tjheseletsa ea letheba.
- Boholo ba Nugget:E 'ngoe ea litšobotsi tsa bohlokoa ka ho fetisisa ke boholo ba nugget ea weld. Nugget ke letamo la tšepe le qhibilihisitsoeng le entsoeng sebakeng sa ho kopana pakeng tsa li-electrode. E lokela ho ba le boholo bo itseng le sebōpeho, tse ka fapana ho itšetlehile ka li-parameter tsa welding le botenya ba thepa. Nugget e loketseng hangata e pota-potile ebile e lekana ka boholo, e bolelang chese e tiileng le e tšepahalang.
- Botebo ba ho Kena:Botebo boo cheselle e fetelang ka har'a thepa ke karolo ea bohlokoa ea boleng ba weld. Ho kenella ka mokhoa o nepahetseng ho tiisa maqhama a matla pakeng tsa maqephe a kopantsoeng. Ho kenella ka mokhoa o sa fellang ho ka fokolisa lenonyeletso, ha ho kenella ka mokhoa o feteletseng ho ka lebisa ho cheseng kapa ho senya thepa.
- Weld Spatter:Nakong ea ts'ebetso ea ho cheselletsa, marotholi a manyenyane a tšepe a ka ntšoa ka har'a nugget ebe a lula libakeng tse potolohileng. Marotholi ana, a tsejoang e le weld spatter, a ka ama hampe ponahalo le botšepehi ba lenonyeletso. Li-welds tsa boleng bo holimo li bonts'a spatter e nyane.
- Weld Uniformity:Weld e tsitsitseng le e ts'oanang e bohlokoa bakeng sa ho finyella botšepehi ba sebopeho. Liphapano tsa boholo ba li-nugget, botebo ba ho kenella, kapa kabo ea mocheso ka har'a lenonyeletso li ka baka matheba a fokolang kapa likoli tse senyang matla a weld.
- Interfacial Bond:Khokahano pakeng tsa maqephe a mabeli a tšepe e lokela ho theha maqhama a matla a metallurgical. Motsoako o kopantsoeng hantle o etsa bonnete ba hore maqephe a sebetsa e le karolo e le 'ngoe, ho matlafatsa botšepehi ba sebopeho. Khokahano e fokolang ea sefahleho e ka lebisa karohanong kapa delamination ea maqephe.
- Sebaka se Ametsoeng ke Mocheso (HAZ):Ho pota-potile nugget ke sebaka se amehileng ke mocheso, moo tšepe e nang le maikutlo a fapaneng a tšusumetso ea mocheso. Ho bohlokoa ho fokotsa boholo ba HAZ ho qoba liphetoho linthong tse bonahalang, joalo ka ho thatafala kapa brittleness, tse ka senyang ts'ebetso ea weld.
- Ponahalo ea Bokaholimo:Ponahalo e bonahalang ea motsoako oa weld hangata ke pontšo ea boleng ba eona. Sebaka sa ho hanyetsa se entsoeng hantle se lokela ho ba le bokaholimo bo boreleli le bo tsitsitseng, bo se nang mekhoa e sa tsitsang, mapetsong, kapa ho fifala ho feteletseng.
- Teko le Tlhahlobo:Ho netefatsa ho ts'epahala ha li-welds tsa ho hanyetsa, ho sebelisoa mekhoa e fapaneng ea tlhahlobo e sa senyeheng le e senyang. Tsena li kenyelletsa tlhahlobo ea pono, tlhahlobo ea ultrasonic, tlhahlobo ea X-ray, le tlhahlobo ea peel, hara tse ling.
Qetellong, ho utloisisa litšoaneleho tsa ho tjheseletsa manonyeletso a hlahisoang ke mechini ea tjheseletsa ea letheba ke ea bohlokoa bakeng sa ho fihlela li-welds tsa boleng bo holimo le tse tšepahalang. Baetsi le litsebi tsa ho cheselletsa litšepe li tlameha ho beha leihlo likarolo tsena ka hloko ho netefatsa hore likarolo tse cheselitsoeng li kopana le maemo a lakatsehang a matla le ho tšoarella, haholo lits'ebetsong tsa bohlokoa joalo ka tlhahiso ea likoloi le sefofane. Koetliso e nepahetseng, taolo e nepahetseng ea paramethara, le mehato e matla ea taolo ea boleng ke senotlolo sa ho lula ho hlahisa li-welds tse phahameng tsa ho hanyetsa.
