Ọkpụkpụ dị na eriri weld bụ ihe a na-ahụkarị n'ogerobot ịgbado ọkụ. Ọnụnọ nke pores nwere ike iduga mbelata ike nke welds, na ọbụna mee ka mgbawa na mgbaji. Isi ihe kpatara e guzobere pores na welds robot gụnyere ihe ndị a:
1. Nchekwa gas na-adịghị mma:
N'oge usoro ịgbado ọkụ, ọkọnọ nke na-echebe gas (dị ka argon, carbon dioxide, wdg) bụ ezughi oke ma ọ bụ na-erughị eru, nke na-ada ada n'ụzọ dị irè ikewapụ oxygen, nitrogen, wdg na ikuku, na-akpata gas agwakọta n'ime gbazee ọdọ mmiri na. nhazi nke pores.
2. Ogbenye elu ọgwụgwọ nke ịgbado ọkụ ihe na isi ihe:
Enwere adịghị ọcha dị ka ntụpọ mmanụ, nchara, mmiri mmiri, na akpịrịkpa oxide n'elu ihe ịgbado ọkụ ma ọ bụ ígwè ntọala. Ihe adịghị ọcha ndị a na-erekasị na okpomọkụ ịgbado ọkụ dị elu iji mepụta gas, nke na-abanye n'ọdọ mmiri a wụrụ awụ wee mepụta pores.
3. Usoro ịgbado ọkụ na-ekwesịghị ekwesị:
Ọ bụrụ na nke ugbu a, voltaji, na ịgbado ọkụ ọsọ dị oke ma ọ bụ dị ala, na-akpata ezughị ezu ịkpali ọdọ mmiri gbazee na enweghị ike nke gas ịgbanarị were were; Ma ọ bụ ọ bụrụ na ikuku ikuku nke gas nchebe adịghị mma, ọ nwere ike imetụta mmetụta nchebe gas.
4. Nhazi weld enweghị ezi uche:
Ọ bụrụ na ọdịiche dị n'etiti weld seams bụ oke ibu, na fluidity nke ọdọ mmiri a wụrụ awụ metal dara ogbenye, na gas na-esi ike ihapu; Ma ọ bụ ọdịdị nke eriri weld dị mgbagwoju anya, gas adịghịkwa mfe ịgbanarị na omimi nke eriri weld.
5. Oke iru mmiri na gburugburu ịgbado ọkụ:
Mmiri dị n'ikuku na-abanye n'ime hydrogen gas na okpomọkụ ịgbado ọkụ dị elu, nke nwere nnukwu solubility na ọdọ mmiri a wụrụ awụ na-apụghị ịgbanahụ n'oge n'oge usoro jụrụ oyi, na-akpụ pores.
Usoro iji dozie nsogbu nke porosity na robot weld bụ ndị a:
1. Na-ebuli nchebe gas:
Jide n'aka na ịdị ọcha nke gas na-echebe na-ezute ọkọlọtọ, ọnụ ọgụgụ na-agba ọsọ na-agafeghị oke, na anya dị n'etiti nozzle na weld seam kwesịrị ekwesị, na-eme ka mkpuchi mkpuchi ikuku dị mma.
●Jiri ngwakọta gas kwesịrị ekwesị na ngwakọta ngwakọta, dị ka iji mkpanaka ịgbado ọkụ hydrogen dị ala ma ọ bụ nke dị ala, iji belata isi iyi gas hydrogen.
2. Ọgwụgwọ elu siri ike:
Hichaa nke ọma elu nke ahụihe ịgbado ọkụna metal base tupu ịgbado ọkụ, wepụ ihe adịghị ọcha dị ka mmanụ, nchara na mmiri, ma mee ọgwụgwọ preheating ma ọ bụrụ na ọ dị mkpa.
Maka gburugburu ebe mmiri nwere ike ịpụta n'oge usoro ịgbado ọkụ, were usoro ihicha, dị ka iji igwe draịva weld ma ọ bụ kpochaa ihe arụ ọrụ.
3. Gbanwee welding usoro parameters:
Họrọ ihe kwesịrị ekwesị ugbu a, voltaji, na ịgbado ọkụ dabere na ihe ịgbado ọkụ, isi ihe, na ịgbado ọkụ ọnọdụ iji hụ na agafeghị oke mkpali na gas mgbapụ oge nke ọdọ mmiri a wụrụ awụ.
Gbanwee nkuku ikuku nke gas na-echebe iji hụ na gas na-ekpuchi nke ọma n'úkwù weld.
4. Melite nhazi weld:
Jikwaa oghere nke weld n'ime oke ezi uche dị na ya iji zere ịdị oke ma ọ bụ pere mpe.
Maka welds dị mgbagwoju anya, enwere ike iji ụzọ dị ka ịgbado ọkụ nkewa nkewa, metal preset filler, ma ọ bụ ịgbanwe usoro ịgbado ọkụ, enwere ike iji kwalite ọnọdụ mkpofu gas.
5. Control ebe ịgbado ọkụ:
Gbalịa ịgbado ọkụ n'ebe kpọrọ nkụ na ikuku ikuku ka ịzena oke iru mmiri.
Maka gburugburu ebe enweghị ike ịchịkwa iru mmiri, enwere ike ịtụle usoro dịka iji hygroscopics na ikpo ọkụ ịgbado ọkụ iji belata mmetụta nke mmiri.
6. Nleba anya na njikwa mma:
Na-elele mgbe niile arụmọrụ nke ngwa ịgbado ọkụ, dị ka gas eruba mita, ịgbado ọkụ nozzles, wdg, iji hụ na ha ezi ọnọdụ ọrụ.
Nleba anya oge ịgbado ọkụ usoro, dị ka iji a ịgbado ọkụ usoro nlekota oru, ngwa ngwa ịchọpụta na mezie ndiiche parameters.
Mee ule na-adịghị emebi emebi (dị ka nnwale ultrasonic, nyocha redio, wdg) mgbe ịgbado ọkụ gachara ozugbo ịchọpụta ma gwọọ welds nwere porosity. Ngwa zuru oke nke usoro ndị a dị n'elu nwere ike ibelata ọgbọ nke pores na weld robot ma melite ogo ịgbado ọkụ.
Ihe na-akpata porosity na weld robot gụnyere mmetọ elu nke ihe ịgbado ọkụ, nchekwa gas ezughi oke, njikwa na-ezighi ezi nke ịgbado ọkụ ugbu a na voltaji, yana oke ịgbado ọkụ. Iji dozie nsogbu a, anyị kwesịrị ime ihe kwekọrọ ekwekọ, gụnyere iji ihe ịgbado ọkụ dị ọcha, ịhọrọ gas nchebe n'ụzọ ziri ezi na ịchịkwa ọnụego erute, ịtọ ntọala ịgbado ọkụ n'ụzọ ziri ezi, na ịchịkwa ọsọ ịgbado ọkụ dịka ọnọdụ ahụ siri dị. Naanị site n'otu oge na-agwa ọtụtụ akụkụ ka anyị nwere ike igbochi ma dozie nsogbu nke porosity na welds robot, ma melite ogo ịgbado ọkụ.
