Resistance spot welding ke mokhoa o sebelisoang haholo indastering ea tlhahiso, e tsebahalang ka bokhoni ba eona ba ho theha maqhama a matla le a tšepahalang lipakeng tsa likarolo tsa tšepe. Bohareng ba ts'ebetso ena ea tjheseletsa ke mochini oa tjheseletsa oa sebaka sa ho hanyetsa, e leng sesebelisoa sa bohlokoa se bapalang karolo ea bohlokoa ho fihlelleng li-welds tse nepahetseng le tse sebetsang hantle. Sehloohong sena, re tla shebana le likarolo tse fapaneng tsa mochini oa ho tjheseletsa mochini oa ho hanyetsa le karolo ea ona ea bohlokoa ts'ebetsong ea welding.

Likarolo tsa Resistance Spot Welding Machine Workbench
Sebaka se tloaelehileng sa mochini oa ho tjheseletsa mochini oa ho lahla se na le likarolo tse 'maloa tsa bohlokoa:
- Hlooho ea Welding: Hlooho ea ho tjheseletsa ke karolo ea mochine o tsamaisang motlakase ho likarolo tsa tšepe tse lokelang ho etsoa. E na le li-electrode tsa koporo tse sebelisang khatello ho li-workpieces, ho netefatsa hore ho na le puisano e ntle ea motlakase.
- Transformer: Transformer e na le boikarabelo ba ho fetola motlakase oa ho kenya letsoho hore e be motlakase o loketseng oa ho tjheseletsa. E etsa bonnete ba hore ea hona joale e boemong bo nepahetseng bakeng sa ho finyella weld e lakatsehang.
- Lekhotla la taolo: Phanele ea taolo e lumella opareitara ho beha liparamente tse joalo ka welding hajoale, nako le khatello. Litlhophiso tsena li bohlokoa ho fihlela li-welds tse tsitsitseng le tsa boleng bo holimo.
- Sebaka sa mosebetsi: Sebaka sa mosebetsi ke sebaka seo ts'ebetso ea welding e etsoang ho sona. E tlameha ho ba e tiileng le e etselitsoeng ho boloka lisebelisoa tsa mosebetsi li sireletsehile nakong ea welding.
Mokhoa oa ho Welding
Ts'ebetso ea ho tjheseletsa sebaka sa ho hanyetsa e qala ka mosebeletsi ea behang likarolo tsa tšepe tse tla kopanngoa holim'a benche ea mosebetsi. Joale li-electrode tsa hlooho ea welding li behiloe holim'a li-workpieces. Ha potoloho ea welding e qala, motlakase oa motlakase o fetisoa ka li-electrode le ho li-workpieces. Hona joale hona joale ho hlahisa mocheso ka lebaka la ho hanyetsa ha tšepe, ho etsa hore e qhibilihe ebe e theha maqhama.
Nako ea potoloho ea welding, hammoho le hona joale le khatello e sebelisoang, e laoloa ka hloko ke mosebeletsi ka phanele ea taolo. Litekanyetso tsena li tlameha ho hlophisoa hantle ho netefatsa boleng le matla a weld. Hang ha potoloho ea welding e phethiloe, li-electrode lia phahamisoa, 'me motsoako o sa tsoa thehoa oa weld o lumelloa ho pholile le ho tiisa.
Melemo ea Resistance Spot Welding
Resistance spot welding e fana ka melemo e mengata:
- Lebelo: Ke ts'ebetso ea ho cheselletsa ka potlako, e etsang hore e tšoanelehe bakeng sa tlhahiso ea boleng bo phahameng.
- Ho lumellana: Ka ho seta le taolo e nepahetseng, welding spot welding e hlahisa li-welds tse tsitsitseng le tse phetoang.
- Matla: Li-welds tse entsoeng ka mokhoa ona li matla ebile lia tšoarella.
- Bohloeki: Ho fapana le mekhoa e meng ea ho tjheseletsa, welding spot welding ha e hlahise mosi o mongata, mosi kapa splatter.
Qetellong, sebaka sa ho hanyetsa mochini oa ho tjheseletsa mochini o sebetsang ke karolo ea bohlokoa indastering ea ho etsa tšepe. Bokhoni ba eona ba ho theha li-welds tse matla, tse ka tšeptjoang le tse tsitsitseng li etsa hore e be ea bohlokoa haholo lits'ebetsong tse fapaneng tsa tlhahiso. Ho utloisisa likarolo le ts'ebetso ea welding ka boeona ke ea bohlokoa bakeng sa ba sebetsang ho finyella sephetho se lakatsehang le ho netefatsa botšepehi ba manonyeletso a marang-rang.
