Selelekela sa ho Welding, Pre-Pre-Pressure, le Ho Tšoara Nako ka Mechining ea ho Welding ea Maqhubu a Medium-Frequency Spot

Mechini ea welding e nang le maqhubu a mahareng e itšetlehile ka li-electrode tse bōpehileng hantle ho fumana li-welds tse sebetsang hantle le tse tšepahalang.Sebopeho sa elektrode se bapala karolo ea bohlokoa ho theha khokahano e nepahetseng le lisebelisoa tsa mosebetsi le ho netefatsa hore mocheso o ajoa.Sengoliloeng sena se bua ka ts'ebetso ea ho bopa li-electrode tse tloaelehileng tse sebelisoang mochining oa tjheseletsa oa maqhubu a mahareng a maqhubu a mahareng.

1. Khetho ea Lisebelisoa tsa Electrode: Pele o theha li-electrode, ho bohlokoa ho khetha thepa e nepahetseng ea elektrode ho latela litlhoko tse khethehileng tsa welding.Lisebelisoa tse tloaelehileng tsa electrode li kenyelletsa koporo, chromium-koporo, le li-alloys tsa koporo tsa zirconium.Lisebelisoa tsena li na le conductivity e ntle ea motlakase, conductivity ea mocheso, le ho hanyetsa ho roala, ho li etsa hore li tšoanelehe bakeng sa lits'ebetso tse sebetsang hantle tsa welding.
2. Moralo oa Electrode: Moralo oa li-electrode o ipapisitse le ts'ebeliso ea welding le sebopeho sa li-workpieces.Sebopeho sa electrode se lokela ho lumella ho lumellana hantle, sebaka se lekaneng sa ho kopana, le ho fetisa mocheso o sebetsang hantle.Meetso e tloaelehileng ea li-electrode e kenyelletsa li-electrode tse bataletseng, li-electrode tse bōpehileng joaloka dome, le li-electrode tsa cylindrical.Khetho ea moralo oa li-electrode e susumetsoa ke lintlha tse kang botenya ba thepa, tlhophiso ea kopanelo, le boleng ba weld bo lakatsehang.
3. Electrode Shaping Process: Ts'ebetso ea ho bopa li-electrode e kenyelletsa mehato e mengata ho fihlela sebopeho le boholo bo lakatsehang.Mona ke kemiso e akaretsang ea ts'ebetso ea ho bopa li-electrode:

   a.Ho khaola: Qala ka ho seha thepa ea elektrode ka bolelele bo lakatsehang u sebelisa sesebelisoa kapa mochini o loketseng oa ho itšeha.Etsa bonnete ba ho khaola ho nepahetseng le ho hloeka ho boloka ho nepahala ha sebopeho sa electrode ea ho qetela.

   b.Shaping: Sebelisa lisebelisoa tse khethehileng tsa ho etsa sebopeho kapa mochini ho bopa lisebelisoa tsa elektrode ka mokhoa o lakatsehang.Sena se ka 'na sa akarelletsa ho kobeha, ho sila, ho sila kapa ho sebetsa ka mechine.Latela litlhaloso le litekanyo tse hlokahalang bakeng sa moralo o khethehileng oa li-electrode.

   c.Qetella: Ka mor'a ho bopa, etsa mekhoa leha e le efe e hlokahalang ea ho qeta ho nolofatsa sebaka sa electrode.Sena se ka kenyelletsa polishing, deburring, kapa ho roala eleketrode ho matlafatsa ts'ebetso ea eona e tšoarellang le ho sebetsa.

   d.Ho kenngoa ha Electrode: Hang ha li-electrode li bōpehile 'me li felile, li kenye ka mokhoa o sireletsehileng ka har'a li-electrode kapa liphaka tsa mochine oa ho tjheselletsa letheba la inverter.Etsa bonnete ba ho tsamaisana hantle le ho tiisa ka thata ho boloka botsitso ba li-electrode nakong ea ts'ebetso ea welding.

Ho theha li-electrode tse tloaelehileng bakeng sa mechini ea welding ea maqhubu a mahareng ke mohato oa bohlokoa ho fihlela li-welds tse sebetsang hantle le tse tšepahalang.Ka ho khetha thepa e nepahetseng ea li-electrode, ho theha li-electrode ho latela litlhoko tsa welding, le ho latela mekhoa e nepahetseng ea ho bōpa, basebetsi ba ka etsa bonnete ba hore ba kopana hantle, ho fetisa mocheso le boleng ba weld.Ho ela hloko lintlha tse qaqileng le ho nepahala ha ho etsoa ha li-electrode ho kenya letsoho ts'ebetsong ea kakaretso le nako e telele ea lisebelisoa tsa ho tjheseletsa.
