Khatello e Fetoha Joang Nakong ea ho Welding Spot ea Mid-Frequency Spot?

Ho tjheseletsa sebaka sa Mid-frequency spot, eo hape e tsejoang e le medium-frequency resistance welding, ke mokhoa o sebelisoang haholo liindastering tse fapaneng bakeng sa ho kopanya likarolo tsa tšepe. Nakong ea ts'ebetso ea welding, likarolo tse 'maloa li bapala karolo ea bohlokoa ho khetholla boleng ba weld. E 'ngoe ea litekanyetso tsena ke khatello e sebelisoang, e nang le tšusumetso e kholo ts'ebetsong ea welding le matla a kopantsoeng a hlahisoang. Sehloohong sena, re tla hlahloba hore na khatello e fetoha joang nakong ea welding ea maqhubu a mahareng le litlamorao tsa eona ho boleng ba weld.

Khatello ke parameter ea bohlokoa nakong ea tjheseletsa ea letheba, kaha e susumetsa kamano pakeng tsa lisebelisoa tsa mosebetsi le li-electrode, kahoo e ama tlhahiso ea mocheso le phallo ea thepa. Bohareng ba maqhubu a marang-rang, khatello e sebelisoang pakeng tsa li-electrode le li-workpieces li fetoha ka ho khetheha nakong eohle ea tjheseletsa.

1. Lebitso la Pele: Ha li-electrode li ntse li atamela li-workpieces, khatello e qala ho eketseha. Khatello ena ea pele ea ho ikopanya e tiisa hore ho na le motlakase o motle oa motlakase le ho hlahisa mocheso o nepahetseng sebakeng sa welding.
2. Khatello Phase: Hang ha li-electrode li kopana le li-workpieces, khatello e tsoela pele ho phahama ha li-electrode li hatella lisebelisoa hammoho. Mokhahlelo ona oa khatello ke oa bohlokoa bakeng sa ho theha sebaka se tšoanang sa ho ikopanya le ho fokotsa likheo life kapa life tsa moea tse ka amang boleng ba weld.
3. Tšebeliso ea hona joale ea Welding: Ha ts'ebetso ea welding e ntse e sebelisoa, ho hanyetsa ha sebopeho ho hlahisa mocheso, ho lebisang ho qhibiliha ha thepa ea sebakeng seo. Nakong ena, khatello e ka 'na ea e-ba le ho theoha hanyenyane ka lebaka la ho nolofala ha lisebelisoa le ho thehoa ha nugget e entsoeng ka ho qhibilihisoa.
4. Tšoara Mokhahlelo: Ka mor'a hore motlakase oa welding o tima, khatello e bolokoa ka nako e khutšoanyane nakong ea ho tšoara. Mokhahlelo ona o lumella thepa e entsoeng ka ho qhibilihisoa ho tiisa le ho theha motsoako o matla oa weld. Khatello e tiisa hore ho tiisa ho etsahala ka ho lumellana hantle, ho fokotsa ho sotha.
5. Mokhahlelo oa ho Pholisa: Ha motsoako oa weld o theoha, khatello e ka lokolloa butle-butle. Leha ho le joalo, boemo bo itseng ba khatello bo ntse bo ka sebelisoa ho thibela ho khopama kapa ho khopama ho bakoang ke ho tsidifala ka potlako.

Phapang ea khatello nakong ea ts'ebetso ea ho cheselletsa sebaka se bohareng ba maqhubu e ama ka kotloloho boleng le bots'epehi ba weld. Taolo e nepahetseng ea khatello e kenya letsoho likarolong tse latelang:

1. Tlhahiso ea Nugget: Khatello e nepahetseng e tiisa hore thepa e entsoeng ka ho qhibilihisoa e ajoa ka mokhoa o ts'oanang, e etsa nugget e matla le e tsitsitseng ea weld. Khatello e sa lekaneng e ka lebisa ho thehoa ha nugget e sa lekaneng le manonyeletso a fokolang.
2. Porosity e fokolang: Khatello e lekaneng e thusa ho fokotsa ho ba teng ha lipokotho tsa moea le li-voids ka har'a weld. Ho se phethahale hona ho ka fokolisa lenonyeletso le ho fokotsa matla a lona a ho jara.
3. Phokotso ea ho sotha: Ho laola khatello nakong ea pholileng ho thibela ho fokotseha ka potlako le ho sotha ho latelang ha likarolo tse cheselitsoeng.
4. E Ntlafetseng ea Motlakase le Thermal Conductivity: Khatello e nepahetseng e ntlafatsa ho kopana pakeng tsa li-electrode le li-workpieces, e leng se lebisang ho ntlafatso ea motlakase le mocheso oa mocheso, ho fella ka ho hlahisa mocheso o sebetsang hantle.

Sebakeng sa ho cheselletsa mabala a mahareng a maqhubu, phapano ea khatello e bapala karolo ea bohlokoa ho khethollang boleng le ts'epahalo ea manonyeletso a weld. Ho tloha ka lekhetlo la pele ho ea karolong ea ho pholile, ho laola khatello ho tiisa ho phalla ha thepa e nepahetseng, ho thehoa ha nugget, le botšepehi bo kopanetsoeng. Baetsi le li-welding operators ba tlameha ho beha leihlo ka hloko le ho laola likhatello tsa khatello ho finyella li-welds tse tsitsitseng le tsa boleng bo phahameng, tse tlatsetsang ho ts'ebetsong ea kakaretso ea sebopeho sa likarolo tse entsoeng.
