Ts'ebetsong ea ho tjheseletsa sebaka sa maqhubu a mahareng a maqhubu a mahareng, sebopeho sa fusion nugget se bapala karolo ea bohlokoa ho fihlela weld e matla le e tšepahalang. Sengoliloeng sena se ikemiselitse ho hlalosa mohopolo oa "fusion nugget" le ho kenella ts'ebetsong ea sebopeho sa eona ka "medium-frequency inverter spot welding".
- Fusion Nugget: The fusion nugget e bua ka sebaka sa lehae sa thepa e qhibilihisitsoeng e hlahang nakong ea ts'ebetso ea welding. Ke phello ea mocheso o matla o hlahisoang ke khanyetso ea motlakase pakeng tsa li-workpieces le hona joale ho sebelisoa welding. The fusion nugget e na le boikarabelo ba ho kopanya lisebelisoa tsa mosebetsi hammoho, ho theha motsoako o tiileng le o tšoarellang oa weld.
- Ts'ebetso ea Fusion Nugget Formation: Ho theoa ha fusion nugget ho welding ea sebaka sa maqhubu a mahareng ho kenyelletsa mekhahlelo e mengata:
a. Kopana le Compression: Lisebelisoa tse lokelang ho chesetsoa lia kopana 'me li hatelloa hammoho ke matla a electrode. Sena se tiisa kamano e haufi-ufi mme se theha tsela ea conductive bakeng sa hona joale oa welding.
b. Ho futhumatsa: Hang ha li-workpieces li kopane, ho fetisoa hona joale ho tjheseletsa holimo ho tsona. Ho hanyetsa motlakase ho sebopeho se hlahisang mocheso, ho phahamisa mocheso ka potlako sebakeng sa ho kopana. Mocheso o etsa hore thepa e be bonolo 'me qetellong e qhibilihe, ho etsa letamo le qhibilihisitsoeng.
c. Ho Kopanya le ho Tiisa: Ha motlakase o ntse o tsoela pele ho phalla, lintho tse entsoeng ka ho qhibilihisoa tse tsoang likarolong tse peli tsa mosebetsi li kopana hammoho ka letamong le entsoeng ka ho qhibilihisoa. Sena se khothalletsa ho ata ha liathomo le ho thusa ho thehoa ha maqhama a metallurgical pakeng tsa thepa ea workpiece. Letamo le qhibilihisitsoeng ebe le qala ho tiea ha mocheso o fela, ho etsa nugget ea fusion.
d. Ho pholisa le ho Tiisa: Ka mor'a hore motlakase oa welding o tingoe, fusion nugget e qala ho pholile le ho tiea. Sekhahla sa ho pholisa se ama microstructure le thepa ea mechine ea weld. Pholiso e laoloang e lumella ho thehoa ha mekhahlelo ea metallurgical e lakatsehang le ho tiisa matla a nepahetseng a weld.
- Lintlha tse Susumetsang Sebopeho sa Fusion Nugget: Lintlha tse 'maloa li ka ama sebopeho sa fusion nugget ka har'a li-welding tse mahareng tsa inverter spot welding:
- Hona joale welding: Boholo ba hona joale oa ho cheselletsa bo ama ka ho toba moloko oa mocheso 'me, ka lebaka leo, boholo le botebo ba nugget ea fusion.
- Matla a Electrode: Khatello e sebelisitsoeng e etsa qeto ea sebaka sa ho kopana pakeng tsa lisebelisoa tsa mosebetsi, e amang kabo ea mocheso le sebopeho sa nugget.
- Nako ea ho cheselletsa: Nako ea ts'ebetso ea welding e ama palo ea mocheso le boholo ba fusion nugget.
- Thepa ea lintho tse bonahalang: The conductivity, botenya, le sebopeho sa thepa ea workpiece e susumetsa khanyetso ea bona ho phallo ea hona joale, ka lebaka leo, ho hlahisa mocheso le ho kopanya nugget.
The fusion nugget ke karolo ea bohlokoa ho fihlella weld e atlehileng ka har'a li-welding tse mahareng tsa maqhubu a mahareng. Ho utloisisa ts'ebetso ea ho theha nugget ea fusion le lintlha tse e susumetsang ho ka thusa ho ntlafatsa liparamente tsa welding, ho laola boleng ba weld, le ho netefatsa matla le ho tšoarella ha motsoako oa weld. Ka ho laola ka hloko hona joale, matla a electrode, nako ea ho tjheseletsa, le thepa ea thepa, li-welders li ka finyella sebopeho se tsitsitseng le se ka tšeptjoang sa fusion nugget, se lebisang ho li-welds tsa boleng bo phahameng.
