Kungani Umshini Welding Wesitoreji Samandla Ubangela Ukushisela Kwamanga?

Ekwenziweni kwezimboni zanamuhla,Imishini Yokushisela Isitoreji Samandlaseziphenduke izinto ezibalulekile kuwo wonke ama-elekthronikhi anembile, izingxenye zezimoto, kanye{0}}nokwakhiwa kwensimbi engeyona eyensimbi ngenxa yamandla azo okuphuma ngokushesha okukhulu, ukushisa okuncane{1}}kwezindawo ezithintekile, nokusebenza kahle kwamandla. Nokho abakhiqizi abaningi babhekana nenkinga eqhubekayo neyingozi: ama-welds angamanga. Lezi zinkinga zibonakala zizwakala ngaphandle kodwa azinayo ibhondi ye-metallurgical efanele ku-weld nugget, okuholela ekuqineni okukhulu kwamalunga okuvame ukuholela ekuhlulekeni phakathi nokuhlanganisa, ukucubungula, noma isevisi.

Ukushisela okungamanga akwenzeki ngokungahleliwe-kubangelwa ukungalingani phakathi kwezinto ezine ezibalulekile: amapharamitha wamandla, umfutho we-electrode, isimo sendawo yokusebenza, nokusebenza kwezisetshenziswa. Ake sihlole imbangela ngayinye ngokuningiliziwe.

Imishini yokushisela i-Energy Storage isebenza ngokugcina amandla kagesi kuma-capacitor futhi iwakhulule ngokushesha nge-welding transformer ngama-millisecond. Amandla okushisela (akalwa ngama-joules, J) kufanele afane ncamashi nezinto ezibonakalayo zempahla, okuhlanganisa indawo encibilikayo, ukuguquguquka kwe-thermal, kanye nogqinsi.

Uma amandla esethelwe phansi kakhulu, izindawo zensimbi azikwazi ukufinyelela lapho zincibilika khona ngesikhathi esitholakalayo. Ngenkathi indawo engaphezulu ingase ibonise ukunamathela kancane ekushisiseni kwe-Joule, awekho amafomu ebhondi ye-metallurgical yangempela. Lokhu kuxhumana okubuthaka kwendawo kuphuka kalula phakathi nomshini olandelayo, ukuphatha, noma isevisi.

Ngokweziqondiso zobuchwepheshe ze-Heron, lapho kushiselwa insimbi engu-0.8mm enamandla angaphansi kuka-1200J, ububanzi be-weld nugget ngokuvamile behluleka ukuhlangabezana nemfuneko evamile engu-$\\sqrt{t}$ (lapho u-t kuwugqinsi lwempahla, cishe u-0.9mm), okuholela kumazinga okushisela angamanga angaphezu kuka-30%. Uma amandla esethwe phakathi kuka-1400-1600J, amazinga okushisela amanga ehla ngaphansi kuka-5%.

Ama-Electrode asebenza izindima ezimbili-aqhuba amanje futhi afaka ingcindezi. Noma yikuphi ukuwohloka kwesimo se-electrode kuphazamisa ngokuqondile ikhwalithi yokushisela.

• I-Electrode Wear:Ngokuhamba kwesikhathi, amathiphu e-electrode ayaguga ngenxa yokuthintana okuphindaphindiwe,{0}}ukugibela amabhayisikili aphezulu, kanye nomthelela wokusebenza. Ububanzi buyanda futhi ingaphezulu liba lukhuni. Ngokusho kwedatha yezobuchwepheshe ye-Agera, lapho ububanzi be-electrode bukhuphuka ngo-0.5mm kusukela ekugugile, indawo yokuxhumana iyakhula futhi ukuminyana okusebenzayo kwehla cishe ngo-30%. Lokhu kusho ukuthi ngisho nangamandla okukhipha njalo, ukushisa kwangempela okulethwa endaweni yokushisela kuncipha kakhulu, okuphakamisa ingozi yokushisela okungamanga.
• I-Electrode Pressure enganele:Ingcindezi ye-electrode ithinta ngqo ukumelana nokuxhumana phakathi kwezinto zokusebenza. Ingcindezi engaphansi kuka-2.5kN (yokushisela indawo okujwayelekile) idala ukuthintana okungalungile, ukumelana nokuxhumana okudlulele, kanye nokushabalala kwamandla esixhumi esibonakalayo kunasensimbi. Umfutho ophansi uphinda ubangele isipatha esiningi noma "ubuso{3}}bushise amashisela amanga" lapho ingaphezulu lishisa kuyilapho ingaphakathi lingancibiliki.
• I-Electrode Misalignment:Uma izimbazo zama-electrode zingahambelani noma izindawo zokuthintwa zichezuka endaweni yokuklama, ukusatshalaliswa kwengcindezi kuba nokungalingani-ezinye izindawo zinengcindezi-okubangela ukuhlehla nokushiswa) kuyilapho ezinye zihlala ngaphansi-kunokucindezela (okuthambekele ekushiseleni okungamanga).

Amafilimu e-oksidi, uwoyela, uthuli, nokunye ukungcola kwakha izivimbi{0}}eziphakeme ezithikameza kakhulu ukugeleza kwamanje. Le nkinga ibukhali ikakhulukazi ngama-alloys e-aluminium.

I-Aluminium ngokwemvelo ikhiqiza ifilimu ye-aluminium oxide (Al₂O₃) ekwazi ukumelana nogesi izikhathi ezingaphezu kwezingu-10 ngaphezu kwesisekelo sensimbi. Ngaphandle kokuhlanza indawo yonke, amandla okukhipha ayaphela ngokugqekeza lesi singqimba se-oxide kunokuncibilikisa insimbi. Okuhlangenwe nakho kwemboni kubonisa ukuthi ukulungiswa kwe-aluminium enganele kungaholela emazingeni okushisela amanga afinyelele ku-40%.

Imithelela Engcolisayo Yobuso:

• Amafutha Negrisi: Amafutha okugcoba nezinto ezivimbela ukugqwala emishinini, ekuthumeleni, noma ekugcinweni kwazo kudala izendlalelo ezivikelayo ezivimba ukugeleza kwamanje.
