Resistance spot welding ke ts'ebetso e fapaneng ea ho tjheseletsa e sebelisoang liindastering tse ngata ho kopanya likarolo tsa tšepe hantle. Boleng ba li-welds tsa letheba bo itšetlehile ka lintlha tse 'maloa,' me parameter e le 'ngoe ea bohlokoa ke khatello e sebelisoang ho li-electrode tsa welding. Sehloohong sena, re tla hlahloba tšusumetso e kholo ea khatello ea ts'ebetso ea li-electrode mochining oa ho tjheselletsa letheba.
1. Sebaka sa Kopano sa Electrode
Khatello e sebelisoang ho li-electrode tsa welding e ama ka ho toba sebaka sa ho kopana pakeng tsa li-electrode le workpiece. Khatello e phahameng e fella ka sebaka se seholo sa ho kopana. Sebaka sena se eketsehileng sa ho ikopanya se thusa ho tsamaisa motlakase o betere, ho lebisang ho boleng bo ntlafetseng ba weld. E etsa bonnete ba hore hona joale e phalla ka mokhoa o ts'oanang ka har'a sesebelisoa sa mosebetsi, ho khothalletsa ho kopana ho tsitsitseng le ho matla.
2. Moloko oa Mocheso
Khatello e bapala karolo ea bohlokoa ho laola mocheso o hlahisoang nakong ea ts'ebetso ea ho cheselletsa. Ha li-electrode li sebelisa khatello ho workpiece, ho hanyetsa pakeng tsa tsona ho hlahisa mocheso. Boholo ba khatello bo susumetsa sekhahla sa tlhahiso ea mocheso. Khatello e phahameng e ka hlahisa mocheso o mongata, e leng oa bohlokoa bakeng sa ho finyella fusion e nepahetseng ea weld ka thepa e teteaneng kapa maemo a thata a ho cheselletsa.
3. Phetoho ea Lintho
Khatello e sebelisoang ke li-electrode e ka baka deformation ea thepa ho workpiece. Deformation ena ke ea bohlokoa ka ho khetheha bakeng sa lisebelisoa tse nang le liaparo tse ka holimo kapa tse silafatsang. Ka ho sebelisa khatello e lekaneng, li-electrode li ka phunyeletsa ka holim'a likarolo tse ka holimo, ho netefatsa hore ho na le sebopeho se hloekileng le se se nang litšila. Sena se fella ka li-welds tse matla le tse tšepahalang haholoanyane.
4. Electrode Wear
Le hoja khatello e le ea bohlokoa bakeng sa ho theha li-welds tsa boleng bo phahameng, e ka boela ea ama liaparo tsa electrode. Khatello e feteletseng e ka lebisa ho apara ka potlako ea li-electrode, ho fokotsa nako ea bophelo ba bona. Khatello e leka-lekaneng e ea hlokahala ho fihlela boleng bo tsitsitseng ba weld ha o ntse o fokotsa ho roala ha li-electrode. Li-electrode tse ling li etselitsoe ho mamella likhatello tse phahameng 'me li loketse haholoanyane lits'ebetso tse khethehileng.
5. Mekhoa ea ho Laola Khatello
Mechini ea sejoale-joale ea "resistance spot welding" hangata e kenyelletsa litsamaiso tse tsoetseng pele tsa taolo ea khatello. Litsamaiso tsena li lumella basebelisi ho laola ka nepo le ho beha leihlo khatello e sebelisoang ho li-electrode. Ka ho boloka boemo bo nepahetseng ba khatello ho pholletsa le ts'ebetso ea welding, litsamaiso tsena li kenya letsoho ho boleng bo tsitsitseng ba weld le ho lelefatsa bophelo ba li-electrode.
6. Phapang ea Khatello
Lits'ebetsong tse ling tsa welding, ho ka 'na ha hlokahala hore ho be le likhatello tse fapaneng ho rarolla mathata a itseng. Ka mohlala, ha ho chesetsoa thepa e sa tšoaneng kapa thepa e nang le botenya bo sa tšoaneng, ho fetola maemo a khatello ho ka thusa ho finyella li-welds tse tšoanang. Ho feto-fetoha ha khatello ho ka boela ha sebelisoa ho laola ho kenya mocheso le ho thibela ho khopama lits'ebetsong tse itseng.
7. Tiisetso ea Boleng
Ho laola khatello ke karolo ea bohlokoa ea tiisetso ea boleng ho resistance spot welding. Baetsi ba tlameha ho theha le ho boloka litlhophiso tse nepahetseng tsa khatello ho fihlela litekanyetso le litlhaloso tsa welding. Ho hlahloba nako le nako le ho lekanya litsamaiso tsa taolo ea khatello ke tsa bohlokoa ho netefatsa hore maemo a batloang a khatello a fihlelleha ka linako tsohle.
Qetellong, khatello ke karolo ea mantlha mecheng ea ho tjheseletsa sebakeng sa ho hanyetsa e amang haholo ts'ebetso ea li-electrode le boleng ba weld. Khatello e laoloang hantle e tiisa hore ho kopana ha li-electrode ho nepahetse, ho hlahisa mocheso o sebetsang hantle, ho senyeha ha thepa, le ho fokotsa ho roala ha li-electrode. Litsamaiso tse tsoetseng pele tsa taolo ea khatello li ntlafatsa ho nepahala le ho ts'oana ha li-welds, e leng se etsang hore e be karolo ea bohlokoa ea theknoloji ea sejoale-joale.
