Sebakeng sa "medium-frequency spot welding" ea DC, karolo ea khatello ea welding e ntse e le sehlooho sa bohlokoa haholo. Sengoliloeng sena se shebisisa bohlokoa ba khatello ea welding, litlamorao tsa eona ts'ebetsong ea ho cheselletsa, le lintlha tse hlokang ho hlahlojoa ka hloko.
Welding ke mokhoa o rarahaneng o kenyelletsang ho kopanngoa ha likotoana tse peli tsa tšepe ka ho sebelisa mocheso le khatello. Le hoja bohlokoa ba mocheso ts'ebetsong ena bo tsejoa ka ho pharaletseng, karolo ea khatello ea welding hangata e lula e le tlaase. Sebakeng se mahareng sa DC spot welding, khatello e sebelisoang nakong ea ts'ebetso ea welding e ka ama boleng le bots'epehi ba lenonyeletso la weld.
E 'ngoe ea mabaka a mantlha a etsang hore khatello ea welding e be ea bohlokoa ke tšusumetso ea eona ho hokahaneng ha motlakase lipakeng tsa li-workpieces. Sebakeng se mahareng sa DC spot welding, phallo e sa khaotseng ea hona joale e otlolohileng e feta har'a li-workpieces, e baka ho hanyetsa le ho hlahisa mocheso. Boleng ba ho kopana ha motlakase pakeng tsa li-workpieces bo ameha ka ho toba ke khatello e sebelisoang. Khatello e sa lekaneng e ka lebisa ho se kopane ha motlakase, ho fella ka ho futhumatsa ho sa lekaneng le motsoako o fokolang oa weld.
Ho feta moo, khatello ea welding e phetha karolo ea bohlokoa ho fihlelleng cheselle nugget e tsitsitseng, e leng letamo la tšepe le qhibilihisitsoeng moo ho chesetsoang. Khatello e thusa ho etsa bonnete ba hore li-workpieces li ts'oaroe ka thata hammoho, ho lumella hore ho be le kabo e tšoanang ea mocheso le khatello ho pholletsa le motsoako. Ho tšoana hona ho bohlokoa ho hlahisa li-welds tse matla, tse tšoarellang tse fihlelang litekanyetso tsa indasteri le litlhoko tsa polokeho.
Tšusumetso ea khatello ea welding ha e felle feela ho boleng ba motsoako oa weld. E boetse e susumetsa katleho e akaretsang ea ts'ebetso ea welding. Khatello e sa lekaneng e ka lebisa ho nako e telele ea ho tjheseletsa le ho eketseha ha tšebeliso ea matla, e leng ho amang katleho ea litšenyehelo tsa ts'ebetso ea welding.
Ho tlameha ho nahanoa lintlha tse 'maloa ha ho khethoa khatello e nepahetseng ea welding bakeng sa kopo e fanoeng. Botenya ba thepa, mofuta oa litšepe tse kopantsoeng, boholo ba elektrode le sebopeho, le litlhophiso tsa mochini oa tjheseletsa kaofela li na le karolo ho hlaloseng maemo a nepahetseng a khatello.

Qetellong, khatello ea welding e bohlokoa ka mokhoa o ke keng oa qojoa ho li-welding tsa DC tsa maqhubu a mahareng. E ama ka kotloloho khokahano ea motlakase, sebopeho sa weld nugget, le katleho e akaretsang ea ts'ebetso ea welding. E le ho finyella li-welds tsa boleng bo phahameng le tse ka tšeptjoang, li-welding operators li tlameha ho utloisisa karolo ea khatello le ho sebelisana ha eona le mekhahlelo e fapaneng ea li-welding. Ka ho etsa joalo, ba ka etsa bonnete ba hore mesebetsi ea bona ea ho cheselletsa li-welding e finyella litekanyetso tse hlokahalang le ho hlahisa manonyeletso a matla, a tšoarellang.
