Theho ea Matheba a Weld ka Medium-Frequency Inverter Spot Welding

Matheba a weld a bapala karolo ea bohlokoa ho tjheseletsa sebakeng sa maqhubu a mahareng, ho fana ka manonyeletso a matla le a ts'epahalang lipakeng tsa likarolo tse peli tsa tšepe.Ho utloisisa ts'ebetso ea ho theha sebaka sa weld ho bohlokoa bakeng sa ho ntlafatsa liparamente tsa welding, ho netefatsa li-welds tsa boleng, le ho fihlela thepa e lakatsehang ea mochini.Sehloohong sena, re tla hlahloba mokhoa oa ho theha matheba a weld ho welding ea maqhubu a mahareng a maqhubu.

1. Ikopanye le Compression: Mohato oa pele oa ho theha letheba la weld ke ho theha khokahano le khatello lipakeng tsa malebela a electrode le workpiece.Ha li-electrode li ntse li atamela bokaholimo ba mosebetsi, khatello e sebelisoa ho theha khokahano e thata.Khatello e tiisa kamano e haufi-ufi le ho felisa likheo leha e le life kapa lipokotho tsa moea tse ka sitisang ts'ebetso ea welding.
2. Resistance Heating: Hang ha li-electrode li theha puisano, motlakase o fetisoa ka har'a sesebelisoa sa mosebetsi, o hlahisang mocheso oa ho hanyetsa.Boima bo phahameng ba hona joale sebakeng sa ho kopana bo baka mocheso oa sebaka ka lebaka la ho hanyetsa motlakase oa thepa ea mosebetsi.Mocheso ona o matla o phahamisa mocheso sebakeng sa ho kopana, ho etsa hore tšepe e be bonolo 'me qetellong e fihle moo e qhibilihang.
3. Metal Melting and Bonding: Ha mocheso o ntse o phahama, tšepe e sebakeng sa ho kopana e qala ho qhibiliha.Mocheso o fetisoa ho tloha ho workpiece ho malebela a electrode, e leng se hlahisang ho qhibiliha ha sebaka sa mosebetsi le lisebelisoa tsa electrode.Tšepe e entsoeng ka ho qhibilihisoa e etsa letamo sebakeng sa ho kopana, ho etsa karolo ea mokelikeli.
4. Ho Tiisa le ho Kopana ha 'Muso: Ka mor'a hore letamo la tšepe le qhibilihisitsoeng le thehoe, le qala ho tiea.Ha mocheso o ntse o fela, tšepe ea mokelikeli ea pholile 'me e ea ho tiisa, e khutlela boemong ba eona bo tiileng.Nakong ea ts'ebetso ena ea ho tiisa, ho fetoha ha athomo ho etsahala, ho lumella liathomo tsa "workpiece" le lisebelisoa tsa electrode hore li kopane le ho theha maqhama a metallurgical.
5. Weld Spot Formation: Ho tiea ha tšepe e qhibilihisitsoeng ho fella ka ho thehoa ha sebaka se tiileng sa weld.Sebaka sa weld ke sebaka se kopantsoeng moo lisebelisoa tsa mosebetsi le li-electrode li kopantsoeng hammoho, ho theha motsoako o matla le o tšoarellang.Boholo le sebopeho sa sebaka sa weld se ipapisitse le lintlha tse fapaneng tse kang li-parameter tsa welding, moralo oa li-electrode le thepa ea thepa.
6. Ho Pholisa le ho Tiisa ka Post-Weld: Kamora hore sebaka sa weld se thehoe, ts'ebetso ea ho pholisa e tsoela pele.Mocheso o nyamela ho tloha sebakeng se cheselletsang ho ea libakeng tse potolohileng, 'me tšepe e qhibilihisitsoeng e tiea ka ho feletseng.Mokhahlelo ona oa ho pholisa le oa ho tiisa o bohlokoa bakeng sa ho fihlela thepa e lakatsehang ea metallurgic le ho netefatsa botšepehi ba motsoako oa weld.

Sebopeho sa matheba a tjheseletsa sebakeng se mahareng a maqhubu a inverter letheba tjheseletsa ke ts'ebetso e rarahaneng e kenyelletsang ho ikopanya le ho hatella, ho futhumatsa ho hanyetsa, ho qhibiliha ha tšepe le ho kopanya, ho tiisa, le ho pholisa ka mor'a-weld.Ho utloisisa ts'ebetso ena ho thusa ho ntlafatsa likarolo tsa welding, ho laola boleng ba libaka tsa weld, le ho netefatsa matla a mochini le bots'epehi ba manonyeletso a weld.Ka ho laola ka hloko li-parameter tsa welding le ho netefatsa moralo o nepahetseng oa li-electrode le khetho ea thepa, bahlahisi ba ka lula ba hlahisa matheba a boleng bo holimo lits'ebetsong tsa welding tse mahareng tsa maqhubu a mahareng.
