Lefats'eng la tlhahiso, mechini ea ho cheselletsa linate e bapala karolo ea bohlokoa ho kopanya likarolo ka mokhoa o sireletsehileng. Mechini ena e sebetsa ka mokhoa o fapaneng haholo 'me e ka fumanoa liindastering tse fapaneng, ho tloha ho tsa likoloi ho isa ho tsa kaho. Ho fihlella li-welds tse nepahetseng le tse tšepahalang, ho bohlokoa ho utloisisa melao-motheo e ka morao ho li-parameter tsa welding tse sebelisoang mochining ona.
Nut spot welding ke mokhoa o kenyelletsang ho sebelisa khanyetso ea motlakase ho theha maqhama a matla lipakeng tsa linate le sesebelisoa sa mosebetsi. Boleng ba weld bo itšetlehile ka mefuta e mengata ea li-parameter, e 'ngoe le e' ngoe e phetha karolo ea bohlokoa ho finyella weld e atlehileng. A re ke re hlahlobeng melao-motheo ea bohlokoa ea li-parameter tsena tsa welding.
1. Welding Current
Hona joale oa welding ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa ts'ebetsong ea welding. E lekanya boholo ba mocheso o hlahisoang nakong ea weld. Mocheso o phahameng o baka mocheso o mongata, o ka etsang hore ho be le weld e tebileng le e pharaletseng. Leha ho le joalo, mocheso o feteletseng o ka boela oa lebisa ho sotheheng ha lintho le ho fokolisa lenonyeletso. Ka hona, ho khetha mochini o nepahetseng oa tjheseletsa ho bohlokoa ho fihlela weld e matla, e tsitsitseng.
2. Nako ea ho Welding
Nako ea welding ke parameter e 'ngoe ea bohlokoa. E hlalosa nako ea ho phalla hona joale ka linate le workpiece. Nako e loketseng ea welding e tiisa hore mocheso o hlahisoang o lekane ho theha maqhama a matla ntle le ho baka ho chesa kapa ho chesa. Ho bohlokoa ho fumana tekanyo e nepahetseng ho theha weld e tšepahalang.
3. Matla a Electrode
Matla a eleketrode, a tsejoang hape e le khatello ea welding, a susumetsa kamano pakeng tsa eleketrode le workpiece. Paramethara ena e bohlokoa bakeng sa ho theha weld e tsitsitseng le e ts'oanang. Matla a fokolang haholo a ka lebisa ho se kenelle hantle, ha matla a feteletseng a ka senya thepa e kopantsoeng. Ho boloka matla a nepahetseng a elektrode ho bohlokoa bakeng sa sebaka se atlehileng sa weld.
4. Geometry ea Electrode
Sebopeho le boholo ba li-electrode tse sebelisoang mochining oa ho cheselletsa linate ke lintlha tsa bohlokoa. Electrode geometry e ka ama kabo ea hona joale le khatello nakong ea ts'ebetso ea welding. Ho bohlokoa ho khetha li-electrode tse tsamaellanang le litlhoko tsa ts'ebeliso ho netefatsa hore li-welds le ho qoba litaba tse joalo ka matšoao a cheleng kapa deformation e feteletseng.
5. Thepa Thepa
Thepa e ntseng e chesetsoa le eona e phetha karolo ea bohlokoa ho khethollang litekanyo tsa welding. Lisebelisoa tse fapaneng li na le mekhoa e fapaneng ea conductivity le thepa ea mocheso. Ka hona, ho bohlokoa ho fetola liparamente tsa welding hore li lumellane le lisebelisoa tse itseng tse amehang ho fihlela boleng bo lakatsehang ba weld.
Ka kakaretso, ho utloisisa le ho laola mekhoa ea ho tjheseletsa ka mechine ea ho cheselletsa linate ke tsa bohlokoa bakeng sa ho fumana li-welds tse tšepahalang le tse tsitsitseng. Ka ho lokisa ka hloko hona joale, nako, matla a electrode, geometry ea electrode, le ho nahana ka thepa ea thepa, bahlahisi ba ka etsa bonnete ba hore lihlahisoa tsa bona li finyella litekanyetso tse phahameng ka ho fetisisa tsa boleng le ho tšoarella. Melao-motheo ena e tiisa motheo oa ho tjheseletsa hantle ka metjhini e tjheseletsang linate, e ba etsa disebediswa tsa bohlokwa tlhahisong ya sejwalejwale.
