Nkesa okpomọkụ n'oge ịgbado ọkụ

Okpomọkụ nkesa n'oge ịgbado ọkụ butt bụ akụkụ dị oke mkpa nke na-emetụta usoro ịgbado ọkụ na ịdịmma nke welds na-esi na ya pụta. Ịghọta ka okpomọkụ si dị iche n'ofe mpaghara weld dị mkpa maka ndị na-agbado ọkụ na ndị ọkachamara na ụlọ ọrụ ịgbado ọkụ. Edemede a na-enyocha nkesa okpomọkụ n'oge ịgbado ọkụ, na-akọwapụta mmetụta ya na akụrụngwa weld na-enye nghọta n'ịkwalite usoro ịgbado ọkụ.

1. Nkọwa nke Nkesa Okpomọkụ: Nkesa okpomọkụ na-ezo aka na nkesa okpomọkụ dị iche iche n'ofe nkwonkwo weld n'oge usoro ịgbado ọkụ. Ọ na-esi na mpaghara ngwakọta okpomọkụ dị elu ruo na mpaghara okpomọkụ na-emetụta okpomọkụ (HAZ) na ihe mgbakwasị ụkwụ gbara ya gburugburu.
2. Mpaghara Fusion: Mpaghara ngwakọta bụ mpaghara etiti nke weld ebe okpomọkụ kachasị elu ruru. Ọ bụ ebe ígwè isi na-agbaze ma na-ejikọta ọnụ iji mepụta bead weld. Ịhụ na ntinye okpomoku kwesịrị ekwesị na mpaghara a dị oke mkpa maka inweta iguzosi ike n'ezi weld ụda.
3. Mpaghara Okpomọkụ na-emetụta (HAZ): Gburugburu mpaghara ngwakọta, mpaghara okpomọkụ na-enwe mmetụta dị ala na-enwe okpomọkụ ma e jiri ya tụnyere mpaghara njikọ. Ọ bụ ezie na ọ naghị agbaze, HAZ na-enwe mgbanwe metallurgical nke nwere ike imetụta ihe ndị mejupụtara ya.
4. Nchegbu na mgbagwoju anya fọdụrụnụ: Nkesa okpomọkụ na-emetụta nrụgide fọdụrụnụ na mgbagwoju anya na nhazi welded. Ime ngwa ngwa nke mpaghara ngwakọta na HAZ nwere ike iduga nkwekọ na ịkpata nchekasị, nwere ike ịkpata mgbagha ma ọ bụ mgbawa.
5. Preheating na Post-Weld Heat Treatment (PWHT): Iji chịkwaa nkesa okpomọkụ na ibelata nsogbu ndị nwere ike ime, a na-arụ ọrụ preheating na post-weld heat treatment (PWHT). Ịkpọ ọkụ na-ebuli okpomọkụ metal isi, na-ebelata gradient okpomọkụ ma na-ebelata nrụgide okpomọkụ. PWHT na-enyere aka belata nrụgide fọdụrụnụ ma weghachi ihe onwunwe mgbe ịgbado ọkụ gasịrị.
6. Na-eme ka ihe ndị na-agbado ọkụ na-adị mma: Ịgbanwe usoro ịgbado ọkụ, dị ka ịgbado ọkụ ugbu a, voltaji, ọsọ njem, na ntinye okpomọkụ, na-enye ohere welders ịchịkwa nkesa okpomọkụ. Nhọrọ oke nke ọma na-eme ka ntinye weld banye na ngwakọta nke achọrọ ka ọ na-ebelata ihe ize ndụ nke ikpo oke ọkụ ma ọ bụ ikpo ọkụ.
7. Ntinye ọkụ na ịdị arọ ihe: Ntinye ọkụ na oke ihe na-emetụta nkesa okpomọkụ. Ihe ndị dị arọ nwere ike ịchọ ntinye okpomọkụ dị elu, ebe ihe ndị dị gịrịgịrị na-achọ ịgbado ọkụ na-achịkwa iji gbochie ikpo ọkụ.
8. Nleba anya na njikwa okpomọkụ: Usoro ịgbado ọkụ nke oge a na-agụnye nlekota okpomọkụ na usoro njikwa, na-enye nzaghachi ozugbo na nkesa okpomọkụ. Nke a na-eme mgbanwe n'oge usoro ịgbado ọkụ iji nọgide na-enwe ọnọdụ okpomọkụ kacha mma.

Na mmechi, nkesa okpomọkụ n'oge ịgbado ọkụ butt na-emetụta nke ọma ịdịmma weld, nrụgide fọdụrụnụ na ihe onwunwe. Profaịlụ ọnọdụ okpomọkụ a na-achịkwa nke ọma, site na mpaghara njikọ ruo na mpaghara okpomọkụ na-emetụta ya na metal ala gbara ya gburugburu, dị mkpa maka ịnweta ụda welds. Welders nwere ike bulite okpomọkụ nkesa site preheating, post-weld ọgwụgwọ okpomọkụ, na ukpụhọde welding parameters. Nleba anya na ịchịkwa okpomọkụ na ezigbo oge kwalite ịgbado ọkụ nkenke na-eduga na-agbanwe agbanwe na ntụkwasị obi welds. Site n'ịghọta mkpa nkesa okpomọkụ dị n'oge ịgbado ọkụ, ndị ọkachamara nwere ike ibuli omume ịgbado ọkụ, hụ na nguzosi ike n'ezi ihe, na izute ụkpụrụ ịgbado ọkụ siri ike. Na-emesi njikwa okpomọkụ ike na ọrụ ịgbado ọkụ na-akwado ọganihu na teknụzụ ijikọ igwe ma na-akwalite mmepụta ihe ọhụrụ na ụlọ ọrụ ịgbado ọkụ.
