Lintlha tse tharo tsa bohlokoa tsa Resistance Spot Welding

Resistance spot welding ke ts'ebetso ea ho kopanya e sebelisoang haholo indastering, e tsejoang ka katleho le ts'epahalo ea eona. Ho fihlella li-welds tse atlehileng, likarolo tse tharo tsa bohlokoa li phetha karolo ea bohlokoa ts'ebetsong: nako, nako le khatello.

1. Hona joale: Ntho ea pele, ea hona joale, e bua ka matla a motlakase a fanoang ho ts'ebetso ea welding. Ha ho cheselletsa sebaka sa ho hanyetsa, li-electrode tse peli li kopanya lisebelisoa, 'me motlakase o mongata o feta ho tsona. Hona joale sena se hlahisa mocheso ka lebaka la ho hanyetsa motlakase oa thepa e kopantsoeng. Palo ea hona joale e sebelisoang e tlameha ho laoloa ka hloko, kaha e ama ka ho toba mocheso oa sebaka sa welding. Nako e ngata haholo e ka baka mocheso o feteletseng le tšenyo, athe hanyenyane haholo ho ka fella ka li-welds tse sa fellang.
2. Nako: Ntho ea bobeli ea bohlokoa ke nako, e lumellanang le nako ea phallo ea hona joale ka li-workpieces. Nako eo hona joale e sebelisoang ka eona e lekanya boholo ba mocheso o hlahisoang, ka lebaka leo, botebo ba weld. Tšebeliso e nepahetseng ea nako ea hona joale e tiisa hore lisebelisoa lia qhibiliha le ho kopanya hantle. Nako e khutšoanyane haholo e ka fella ka li-welds tse fokolang, ha nako e feteletseng e ka baka mocheso o feteletseng le tšenyo e ka 'nang ea e-ba teng ho thepa.
3. Khatello: Qetellong, khatello ke matla a sebelisoang ho li-workpieces nakong ea welding. Khatello ke ea bohlokoa ho netefatsa kamano e haufi-ufi pakeng tsa lisebelisoa tse kopantsoeng. Khatello e nepahetseng e thusa ho leleka litšila le li-oxide sebakeng sa welding, ho lumella hore ho be le weld e hloekileng le e matla. Khatello e sa lekaneng e ka fella ka boleng bo bobe ba weld, ha khatello e feteletseng e ka lebisa ho deformation kapa esita le ho phunyeha ha li-workpieces.

Qetellong, resistance spot welding e itšetlehile ka taolo e hlokolosi ea hona joale, nako, le khatello ea ho theha manonyeletso a matla le a ka tšeptjoang. Lintlha tsena tse tharo li tlameha ho lekanngoa hantle hore li tsamaellane le thepa e khethehileng le botenya bo cheselitsoeng. Ha e etsoa ka nepo, "resistance spot welding" e fana ka mokhoa o sebetsang le o sebetsang oa ho kopanya litšepe tse fapaneng, e leng se etsang hore e be ts'ebetso ea mantlha tlhahisong ea sejoale-joale.
