Nchịkọta nke Ngwọta maka Porosity na Nut Projection Welding

Porosity bụ ihe a na-ahụkarị na ịgbado ọkụ nke nut, na-eduga n'ịgbado adịghị ike na enweghị ntụkwasị obi. N'isiokwu a, anyị ga-enye nkọwa zuru ezu nke ngwọta dị iche iche iji dozie porosity na nut projection welding. Site n'itinye usoro ndị a, ndị na-arụ ọrụ nwere ike ibelata ihe omume porosity ma hụ na welds siri ike.

1. Nkwadebe elu: Nkwadebe elu nke ọma dị oke mkpa iji wedata porosity na welding projection nut. Tupu ịgbado ọkụ, ọ dị mkpa ka ihichapụ nke ọma ebe a na-ekekọta akị na workpiece iji wepụ ihe ọ bụla na-emerụ emerụ, dị ka mmanụ, unyi, ma ọ bụ oxides. Enwere ike nweta nke a site na ihicha ihe mgbaze, brushing waya, ma ọ bụ mgbawa abrasive. Ebe dị ọcha na-akwalite ntinye weld ka mma ma na-ebelata ohere nke ịmepụta porosity.
2. Nhọrọ Electrode: Nhọrọ nke electrodes ịgbado ọkụ nwere ike imetụta ọdịdị porosity nke ukwuu. A na-atụ aro ka iji electrodes mee ihe ndị nwere ọkụ eletrik dị elu na obere mmeghachi omume, dị ka ọla kọpa ma ọ bụ ọla kọpa alloys. Eletrọd ndị a na-enyefe ọkụ ka mma ma belata ohere nke ọnyà gas, na-ebelata nhazi nke porosity.
3. Nkwalite ihe ịgbado ọkụ: Imepụta paramita ịgbado ọkụ dị mkpa iji belata porosity. Ekwesịrị iji nlezianya dozie ihe ndị dị ka ịgbado ọkụ ugbu a, oge, na nrụgide iji nweta ogo weld kacha mma. Enweghi ike ịgbado ọkụ ugbu a ma ọ bụ oge ịgbado ọkụ na-ezughị ezu nwere ike ime ka ọgbọ okpomọkụ ezughị oke, na-eduga na porosity. N'aka nke ọzọ, oke ịgbado ọkụ ugbu a ma ọ bụ ogologo oge ịgbado ọkụ nwere ike ịmepụta okpomoku dị ukwuu, na-eme ka ihe ahụ na-ekpo ọkụ ma na-ebute porosity. Ịchọta nguzozi ziri ezi bụ isi ihe na-ebelata porosity.
4. Nchekwa gas: N'ọnọdụ ụfọdụ, iji gas na-echebe nwere ike inye aka belata porosity. Gasị nchekwa, dị ka argon ma ọ bụ helium, na-emepụta ikuku nchebe gburugburu mpaghara weld, na-egbochi ntinye nke ikuku ikuku nke nwere ike itinye aka na porosity. Nke a na-aba uru karịsịa mgbe ị na-agbado ihe ndị na-emeghachi omume ma ọ bụ na gburugburu ebe nwere oke ikuku ikuku.
5. Nlekọta Electrode: Ịkwado electrodes ịgbado ọkụ mgbe niile dị oke mkpa iji gbochie porosity. Ka oge na-aga, electrodes nwere ike imerụ ma ọ bụ na-eyi ya, na-eduga na mbufe ọkụ na-adịghị mma na ụba porosity. Ọ dị mkpa ịsacha ma na-enyocha electrodes mgbe niile, na-ewepụ ihe ọ bụla na-emerụ emerụ ma ọ bụ oxidation. Na mgbakwunye, iji dochie igwe eletrọd eyigoro na-eme ka arụ ọrụ na-aga n'ihu na-ebelata ohere nke porosity.
6. Usoro ịgbado ọkụ: Usoro ịgbado ọkụ kwesịrị ekwesị na-ekere òkè dị ukwuu n'ibelata porosity. Ndị na-arụ ọrụ kwesịrị ijide n'aka na nhazi dị mma n'etiti aku na workpiece, na-enwe nrụgide kwụsiri ike n'oge ịgbado ọkụ, ma zere ike electrode gabigara ókè ma ọ bụ mmegharị ngwa ngwa. Usoro ịgbado ọkụ na-agbanwe agbanwe na nke a na-achịkwa na-enyere aka belata porosity ma mepụta welds dị elu.

Porosity na nut projection welding nwere ike imebi iguzosi ike n'ezi ihe na ike nke welds. Agbanyeghị, site n'ịgbaso azịza ndị akọwapụtara n'isiokwu a, ndị na-arụ ọrụ nwere ike belata okwu porosity nke ọma. Ime nkwadebe nke ọma n'elu ala, ịhọrọ electrodes kwesịrị ekwesị, na-eme ka usoro ịgbado ọkụ dị mma, iji mkpuchi gas, idowe electrodes, na iji usoro ịgbado ọkụ kwesịrị ekwesị bụ usoro dị mkpa iji belata porosity ma nweta welds siri ike na ntụkwasị obi na ngwa ịgbado ọkụ nut.
