Ukuchasana kudlala indima ebalulekileyo kwinkqubo yokufudumeza koomatshini bokuwelda be-inverter ephakathi.Eli nqaku liphonononga impembelelo yokuchasana kwinto yokufudumeza kunye nefuthe layo kwimisebenzi ye-welding ye-spot.
Ukufudumeza kwe-Ohmic:
Ukufudumeza kwe-Ohmic yeyona ndlela iphambili apho ukuxhathisa kuchaphazela ukufudumeza kwi-welding yendawo.Xa umbane wombane udlula kwi-conductor, njenge-workpiece, ubushushu buveliswa ngenxa yokuchasana odibana nayo ngoku.Ubungakanani bobushushu obuveliswayo buhambelana ngokuthe ngqo nokumelana nomqhubi.
Ukutshatyalaliswa kwamandla:
Amandla achithwayo kwi-workpiece inqunywe yimveliso yesikwere yangoku (I ^ 2) kunye nokuchasana (R).Ke ngoko, ukonyuka kokumelana kukhokelela ekulahlekeni kwamandla aphezulu, okukhokelela ekufudumezweni okubaluleke ngakumbi kwendawo yokusebenza ngexesha le-welding.
Iinkcazelo ngeempawu zeMathiriyeli:
Ukuchasana kwezinto eziphathekayo kuphenjelelwa yi-conductivity yayo yombane.Izixhobo ezine-resistivity ephezulu, ezifana ne-alloys okanye insimbi engenasici, zibonisa ukuxhathisa okukhulu kwaye, ngenxa yoko, iziphumo eziphezulu zokufudumeza ngexesha le-welding.
Ubungakanani boMsebenzi kunye neJometri:
Ubungakanani kunye nejometri ye-workpiece iphinda ichaphazele ukuchasana nokufudumeza.Izixhobo zokusebenza ezinkulu zinokumelana okuphezulu ngenxa yokwanda kwemilinganiselo, okukhokelela ekuveliseni ubushushu obuninzi ngexesha lokuwelda.
Qhagamshelana noKuchasa:
Ukuxhatshazwa koqhagamshelwano phakathi kwe-electrode kunye ne-workpiece kunokuchaphazela ukufudumeza kwakhona.Uqhagamshelwano olubi lwe-electrode okanye ukungcoliswa kwendawo kunokwazisa ukuchasana okongeziweyo kwindawo yoqhagamshelwano, ekhokelela kwimiphumo yokufudumeza kwendawo kunye nokungahambelani okunokwenzeka kumgangatho we-weld.
Ukuxhathisa kudlala indima ebalulekileyo kwinkqubo yokufudumeza koomatshini bokuwelda bamaza ombane aphakathi.Ichaphazela ngokuthe ngqo ubungakanani bobushushu obuveliswe kwi-workpiece ngexesha le-welding, kunye nezinto ezinjengeepropati eziphathekayo, ubungakanani be-workpiece, ijometri, kunye nokuchasana koqhagamshelwano okufaka isandla kwisiphumo sokufudumeza ngokubanzi.Ukuqonda impembelelo yokumelana nokufudumeza kubalulekile ekuphuculeni iiparamitha ze-welding, ukuqinisekisa ukusabalalisa ubushushu obufanelekileyo, kunye nokufezekisa ii-welds ezithembekileyo neziphezulu.Ngokulawula kunye nokubeka iliso kumanqanaba okumelana, abaqhubi banokulawula ngokufanelekileyo inkqubo yokufudumeza kwaye bavelise iziphumo ezihambelanayo kwizicelo zabo ze-welding.
