Na Thermal Equilibrium e nkoa e le Medium-Frequency Direct Current Spot Welding?

Lefatšeng la li-welding, ho na le lintlha tse ngata tse amehang ho netefatsa boleng le botšepehi ba sehlahisoa sa ho qetela.E 'ngoe ea lintlha tse joalo ke ho ela hloko tekano ea mocheso ho tjheseletsa sebakeng sa maqhubu a mahareng.Sehloohong sena, re hlahloba bohlokoa ba ho lekanngoa ha mocheso ts'ebetsong ena ea welding le phello ea eona ho weld ea ho qetela.

Welding ea hona joale ea nako e mahareng, eo hangata e bitsoang MFDC spot welding, ke mokhoa o sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa likoloi, sefofane le tlhahiso.E kenyelletsa ho kopanya likotoana tse peli tsa tšepe ka ho sebelisa motlakase ka maqhubu a mahareng, hangata lipakeng tsa 1000 Hz le 10000 Hz, ka li-electroy alloy electrode.Motlakase o hlahisa mocheso, o qhibilihisang tšepe sebakeng sa ho cheselletsa, 'me ha ho pholile, ho thehoa weld e tiileng.

Taba e 'ngoe ea bohlokoa ts'ebetsong ena ke ho fumana tekano ea mocheso.Thermal equilibrium e bolela boemo boo mocheso oa mocheso ho workpiece o leka-lekaneng ka ho lahleheloa ke mocheso, ho fella ka mocheso o tsitsitseng le o laoloang ka har'a sebaka sa welding.Ho finyella tekano ea mocheso ho bohlokoa ka mabaka a 'maloa:

1. Ho lumellana le Boleng: Welding ka mocheso o tsitsitseng o tiisa li-welds tse tsitsitseng le tsa boleng bo phahameng.Lithempereichara tse sa tsitsang li ka baka likoli tse kang porosity, cracking, kapa ho se kenelle ho lekaneng.
2. Thepa e nepahetseng ea Weld: Lisebelisoa tse fapaneng li hloka mocheso o khethehileng oa welding ho fihlela thepa e lakatsehang ea mochini.Tekano ea mocheso e lumella hore ho be le taolo e nepahetseng ea ho kenya mocheso, ho etsa bonnete ba hore weld ea ho qetela e na le matla a hlokahalang le nako e telele.
3. Khopamiso e Nyenyane: Welding e ka baka ho sotheha mosebetsing ka lebaka la ho futhumatsa le ho pholile ho sa tšoaneng.Tekano ea mocheso e thusa ho fokotsa ho khopama, ho netefatsa hore sehlahisoa sa ho qetela se boloka sebopeho le boholo ba sona.
4. Matla a Matla: Ho cheselletsa mocheso ka mocheso o nepahetseng ho fokotsa tšebeliso ea matla le ho fokotsa litšila tsa thepa.Mekhoa e sa sebetseng ea li-welding e ka baka litšenyehelo tse eketsehileng tsa matla le tahlehelo ea thepa.

Ho fihlella tekano ea mocheso ho MFDC ho cheselletsa sebaka ho kenyelletsa taolo e hlokolosi ea liparamente tse fapaneng, ho kenyeletsoa hona joale, voltage, nako ea tjheseletsa, le matla a electrode.Hangata ho sebelisoa mekhoa ea ho hlahloba mocheso le mekhoa ea ho fana ka maikutlo ho boloka mocheso o tsitsitseng nakong eohle ea ho cheselletsa.

Moralo oa mochini oa welding le ona o bapala karolo ea bohlokoa ho fihlelleng tekano ea mocheso.Mekhoa e sebetsang hantle ea ho senya mocheso, ho pholile ka mokhoa o nepahetseng oa li-electrode, le taolo e nepahetseng ea litekanyo tsa welding hoa hlokahala ho netefatsa mocheso o tsitsitseng le o laoloang.

Qetellong, ho leka-lekana ha mocheso ke taba ea bohlokoa ho tjheseletsa sebakeng sa maqhubu a mahareng.E ama ka kotloloho boleng, botsitso, le katleho ea ts'ebetso ea welding.Baenjineri ba li-welding le li-operators ba tlameha ho beha leihlo le ho laola ka hloko liparamente tse fapaneng ho fihlela le ho boloka tekano ea mocheso, ho netefatsa hore weld ea ho qetela e kopana le litekanyetso le litlhaloso tse hlokahalang.
