Resistance spot welding ke ts'ebetso e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa likoloi, sefofane le lisebelisoa tsa elektroniki.Mokhoa ona o kenyelletsa ho kopanya likotoana tsa tšepe tse peli kapa ho feta ka ho sebelisa mocheso le khatello libakeng tse itseng.Boleng ba sebaka sa weld bo bohlokoa bakeng sa ts'ebetso e akaretsang le ho tšoarella ha sehlahisoa se felileng.Sehloohong sena, re tla hlahloba lintlha tse tharo tsa bohlokoa tse susumetsang ho hanyetsa letheba le phello ea tsona ts'ebetsong ea welding le sehlahisoa sa ho qetela.
- Hona Joale Matla (Amperage)
Matla a hajoale, a lekantsoeng ka li-amperes, ke karolo ea mantlha ea ho cheselletsa sebaka sa ho hanyetsa.E etsa qeto ea palo ea mocheso o hlahisoang sebakeng sa welding.Ha hona joale ho le tlase haholo, mocheso o sa lekaneng o hlahisoa, o lebisang ho li-welds tse fokolang le tse sa phethoang.Ka lehlakoreng le leng, hona joale ho feteletseng ho ka baka ho chesa haholo, ho fella ka ho chesa kapa ho senya lisebelisoa tsa mosebetsi.
Ho fihlela boleng bo nepahetseng ba weld, ho bohlokoa ho khetha matla a hajoale a nepahetseng ho latela mofuta oa thepa le botenya.Baenjineri le litsebi tsa ho cheselletsa litšepe ba tlameha ho bala ka hloko le ho beha sejoale-joale ho etsa bonnete ba hore li-welds li ts'epahalla.
- Nako ea ho Welding
Nako ea ho cheselletsa, eo hangata e lekantsoeng ka milliseconds, ke ntlha e 'ngoe ea bohlokoa molemong oa ho cheselletsa sebaka sa ho hanyetsa.E etsa qeto ea hore na nako ea hona joale e phalla nako e kae ka li-workpieces, e amang boholo le matla a weld nugget-karolo e qhibilihisitsoeng le e kopantsoeng ea thepa.
Linako tse khutšoane tsa tjheseletsa li kanna tsa se fane ka mocheso o lekaneng ho theha weld e matla, athe nako e telele haholo e ka lebisa ho nolofatseng lisebelisoa le ho fokotsa matla a weld.Ho fumana tekanyo e nepahetseng ke habohlokoa bakeng sa ho finyella weld ka thepa e lakatsehang.
- Khatello (Electrode Force)
Khatello, e sebelisoang ka li-electrode tsa welding, e phetha karolo ea bohlokoa ho tjheseletsa sebaka sa ho hanyetsa.E etsa hore li-workpiece li kopane haufi-ufi, li netefatsa hore li kopana hantle le motlakase le ho khothalletsa ho fetisa mocheso.Khatello e sebelisoang e lokela ho lekana ho tšoara lisebelisoa hammoho nakong le ka mor'a ts'ebetso ea ho cheselletsa.
Khatello e sa lekaneng e ka lebisa ho boleng bo bobe ba weld, kaha ho ka fella ka likheo pakeng tsa lisebelisoa tsa mosebetsi kapa ho se kenelle ho lekaneng.Ka lehlakoreng le leng, khatello e feteletseng e ka senya kapa ea senya thepa, ea ama hampe kakaretso ea sebopeho.
Qetellong, boleng ba "resistance spot welding" bo susumetsoa haholo ke lintlha tse tharo tsa bohlokoa: matla a hona joale, nako ea ho cheselletsa, le khatello.Ho leka-lekanya liparamente tsena ke habohlokoa bakeng sa ho finyella li-welds tse finyellang litekanyetso tse hlokahalang bakeng sa matla, ho tšoarella le ponahalo.Basebelisi le lienjineri tsa welding ba tlameha ho nahana ka lintlha tsena ka hloko 'me ba lule ba li beha leihlo le ho li lokisa ho netefatsa hore ho na le liphetho tse ntle ka ho fetisisa tse ka khonehang lits'ebetsong tse fapaneng.
