Ngụkọta okpomọkụ ziri ezi dị mkpa na igwe ịgbado ọkụ nut iji hụ na njikwa okpomọkụ kwesịrị ekwesị n'oge usoro ịgbado ọkụ. Ịghọta okpomọkụ na-emepụta na ibufe dị oke mkpa maka ịnọgide na-arụ ọrụ kachasị mma, igbochi ikpo ọkụ, na ịhụ na welds dị elu. Isiokwu a na-enye nyocha nke usoro mgbako okpomọkụ nke a na-eji na igwe ịgbado ọkụ nut, na-akọwa mkpa ha na ngwa ha na-ekpebi oke okpomọkụ.
- Ọgbọ Okpomọkụ: Ọgbọ ọkụ na igwe ịgbado ọkụ nut na-eme nke ọma n'ihi nguzogide eletrik na ebe weld. Enwere ike gbakọọ okpomọkụ a na-emepụta site na iji usoro: Okpomọkụ (Q) = I^2 * R * t Ebe:
- Q bụ okpomọkụ a na-emepụta (na joules ma ọ bụ watts)
- M bụ ịgbado ọkụ ugbu a (na amperes)
- R bụ nguzogide eletrik na ebe weld (na ohms)
- t bụ oge ịgbado ọkụ (na sekọnd)
- Nfefe ọkụ: Ekwesịrị ijikwa ọkụ na-eme n'oge ịgbado ọkụ ka ọ ghara ikpo oke ọkụ. Mgbakọ mbufe ọkụ na-enyere aka ikpebi ikpochapụ ọkụ chọrọ. Usoro mbufe ọkụ na-agụnye ịtụle ihe ndị dị ka ntụgharị, convection, na radieshon. Enwere ike ịkọwa ya dị ka: Q = Q_conduction + Q_convection + Q_radiation Ebe:
- Q_conduction na-anọchi anya okpomọkụ na-ebufe site na kọntaktị ozugbo n'etiti workpiece na electrodes.
- Q_convection na-ekwu maka ịnyefe okpomọkụ site na ikuku gbara ya gburugburu ma ọ bụ ihe na-ajụ oyi.
- Q_radiation na-ezo aka na nnyefe ọkụ site na radieshon electromagnetic.
- Ihe ndị chọrọ jụrụ oyi: Iji nọgide na-arụ ọrụ nke ọma na okpomọkụ, ọnụego ikpo ọkụ ga-adabarịrị na ọnụego ọgbọ okpomọkụ. Enwere ike gbakọọ ihe jụrụ oyi site na iji usoro: Q_dissipation = Q_generation Ebe:
- Q_dissipation bụ ọnụego mgbasa ọkụ (na joules kwa nkeji ma ọ bụ watts)
- Q_generation bụ ọnụego ọgbọ okpomọkụ
Site n'ịgbakọ nke ọma okpomọkụ na-emepụta na ịghọta usoro nnyefe ọkụ, ndị na-arụ ọrụ nwere ike hụ na njikwa okpomọkụ dị mma na igwe ịgbado ọkụ nut. Nke a na-enyere aka igbochi ikpo ọkụ akụrụngwa, bulie ogo weld, ma kwalite arụmọrụ ịgbado ọkụ n'ozuzu ya.
Usoro mgbako ọkụ na-arụ ọrụ dị oke mkpa n'ịchọpụta ọgbọ okpomọkụ, nnyefe ọkụ, na ihe jụrụ oyi n'ime igwe ịgbado ọkụ nut. Site n'ịgbakọ n'ụzọ ziri ezi na ijikwa okpomọkụ, ndị na-arụ ọrụ nwere ike hụ na ọnọdụ ọrụ kachasị mma, gbochie ikpo oke ọkụ, ma nweta welds dị elu. Ịghọta usoro ndị a na-enyere ndị na-ahụ maka ọrụ aka ime mkpebi ziri ezi gbasara usoro ịgbado ọkụ, sistemu jụrụ oyi na ụzọ ikposa ọkụ. N'ikpeazụ, njikwa okpomọkụ kwesịrị ekwesị na-eduga n'ịrụ ọrụ ịgbado ọkụ, ogologo oge ndụ akụrụngwa, yana nkwalite mmepụta na usoro ịgbado ọkụ.
