Medium frequency spot welding ke mokhoa o sebelisoang haholo indastering ea tlhahiso ea ho kopanya likarolo tsa tšepe hammoho. Karolo e 'ngoe ea bohlokoa ts'ebetsong ea mochini o cheselletsang maqhubu a mahareng ke oa ho futhumatsa motlakase. Karolong ena, lisebelisoa tsa ho tjheseletsa li fana ka tekanyo e laoloang ea matla a motlakase ho lisebelisoa tsa mosebetsi, ho etsa sebaka sa sebaka sa mocheso o matla libakeng tsa ho kopana.
Nakong ea mokhahlelo oa ho futhumatsa motlakase, mochini o cheselletsang maqhubu a mahareng o sebelisa motlakase o feto-fetohang (AC) o nang le maqhubu ao hangata a tlohang ho 1000 ho isa ho 10000 Hz. AC ena ea maqhubu a mahareng e khethoa hobane e etsa hore ho be le tekano lipakeng tsa mefuta e meng ea maqhubu a holimo le a tlase. E lumella ho fetisa matla ka katleho le taolo e nepahetseng holim'a mokhoa oa ho futhumatsa.
Mokhahlelo oa ho futhumatsa motlakase o sebeletsa merero e 'maloa ea bohlokoa ts'ebetsong ea ho cheselletsa letheba. Taba ea pele, e futhumatsa likarolo tsa tšepe pele, e fokotsa ho sisinyeha ha mocheso ha ho sebelisoa hona joale oa welding. Ho futhumala hona butle-butle ho fokotsa ho khopama ha thepa le ho thusa ho boloka botšepehi ba sebopeho sa lenonyeletso le cheselitsoeng.
Taba ea bobeli, ho futhumatsa sebakeng sa heno ho nolofatsa likarolo tsa tšepe, ho khothaletsa conductivity e ntle ea motlakase lipakeng tsa li-workpieces. Sena ke sa bohlokoa bakeng sa ho fumana weld e tsitsitseng le e tšepahalang. Tšepe e nolofalitsoeng e boetse e thusa ho tlosa litšila tse ka holimo tse kang li-oxide, ho netefatsa hore ho na le sebopeho se hloekileng sa welding.
Ho feta moo, mohato oa ho futhumatsa motlakase o bapala karolo ea ho finyella phetoho ea metallurgical. Ha tšepe e ntse e futhumala, microstructure ea eona ea fetoha, e lebisang ho matla a ho chesehela le ho tšoarella.
