1. Ezi nhọrọ nke ịgbado ọkụ parameters
(1) ịgbado ọkụ ugbu a na arc voltaji Na CO2 gas na-echebe ịgbado ọkụ, maka nke ọ bụla dayameta nke ịgbado ọkụ waya, e nwere a ụfọdụ iwu n'etiti spatter ọnụego na ịgbado ọkụ ugbu a. N'ime mpaghara mgbanwe dị mkpụmkpụ nke obere ugbu a, ọnụọgụ spatter ịgbado ọkụ dị obere. Mgbe abanye na mma urughuru mgbanwe mpaghara nke elu ugbu a, na ịgbado ọkụ spatter ọnụego bụkwa obere, na ịgbado ọkụ spatter ọnụego bụ ndị kasị ibu na n'etiti mpaghara. Na-ewere waya nke nwere dayameta nke 1.2 mm dị ka ihe atụ, mgbe ịgbado ọkụ ugbu a na-erughị 150A ma ọ bụ karịa 300A, spatter ịgbado ọkụ dị obere, na n'etiti abụọ ahụ, spatter ịgbado ọkụ dị ukwuu. Mgbe ị na-ahọrọ ịgbado ọkụ ugbu a, a ga-ezere ebe ịgbado ọkụ dị ugbu a nwere ọnụ ọgụgụ spatter dị elu dị ka o kwere mee, yana voltaji arc kwesịrị ekwesị ga-adaba mgbe ekpebiela ịgbado ọkụ ugbu a.
(2) Welding waya ndọtị ogologo: The ịgbado ọkụ waya ndọtị ogologo (ie akọrọ elongation) nwekwara mmetụta na ịgbado ọkụ spatter. Ogologo ogologo ịgbado ọkụ nke waya ịgbado ọkụ bụ ibu, ka ibu ịgbado ọkụ spatter bụ. Dịka ọmụmaatụ, maka waya nwere dayameta nke 1.2mm, mgbe ịgbado ọkụ ugbu a bụ 280A, mgbe ogologo ogologo nke waya na-abawanye site na 20mm ruo 30mm, ọnụ ọgụgụ nke ịgbado ọkụ na-abawanye site na 5%. Ya mere, a na-achọrọ na mgbatị ogologo nke waya ịgbado ọkụ kwesịrị mkpụmkpụ
2. Meziwanye isi iyi ịgbado ọkụ
Ihe na-akpata mgbawa na CO2 gas na-echebe ịgbado ọkụ bụ nke kachasị na njedebe ikpeazụ nke mgbanwe mgbanwe dị mkpirikpi, n'ihi mmụba dị elu nke oge dị mkpirikpi, ígwè mmiri mmiri na-ekpo ọkụ na-ekpo ọkụ ngwa ngwa, na-eme ka ikpo ọkụ na-ekpo ọkụ, na n'ikpeazụ, mmiri mmiri na-agbawa iji mepụta splashes. N'ịtụle mma nke ịgbado ọkụ isi iyi, ụzọ ndị dị otú ahụ dị ka usoro njikọ nke reactors na resistors, ugbu a ịmafe, na ugbu a waveform akara na ịgbado ọkụ sekit na-tumadi iji belata nwara ugbu a nke mmiri mmiri mmiri na si otú belata ịgbado ọkụ spatter. Ka ọ dị ugbu a, igwe ịgbado ọkụ CO2 gas na-achịkwa ụdị thyristor-efegharị efegharị na igwe inverter ụdị transistor-ụdị ikuku CO2 gas na-agbado ọkụ ejirila igwe, wee nweta ihe ịga nke ọma n'ibelata spatter nke CO2 gas mkpuchi ịgbado ọkụ.
3. Tinye argon (Ar) na CO2 gas:
Mgbe agbakwunyere ụfọdụ gas argon na CO2 gas, a gbanwere ihe anụ ahụ na kemịkal nke CO2 gas. Na mmụba nke argon gas ruru, ịgbado ọkụ spatter ji nwayọọ nwayọọ na-ebelata, na kasị dị ịrịba ama mgbanwe na spatter ọnwụ bụ mgbe urughuru dayameta karịrị 0.8mm spatter, ma nwere obere mmetụta na spatter na urughuru dayameta na-erughị 0.8mm.
Na mgbakwunye, iji ịgbado ọkụ agwakọta gas na-ekpuchi argon na gas CO2 nwekwara ike imeziwanye nhazi weld. Mmetụta nke ịgbakwunye argon na CO2 gas na ntinye weld, obosara fusion na ịdị elu fọdụrụnụ, na argon na CO2 gas. Ka ọdịnaya gas na-abawanye, omimi ntinye na-ebelata, obosara ngwakọta na-abawanye, ịdị elu weld na-ebelata.
4. Jiri obere spatter ịgbado ọkụ waya
Maka waya siri ike, na premise nke n'ịhụ na n'ibu Njirimara nke nkwonkwo, ibelata carbon ọdịnaya ka o kwere mee, na n'ụzọ kwesịrị ekwesị na-abawanye alloying ọcha dị ka titanium na aluminom nwere ike n'ụzọ dị irè belata ịgbado ọkụ spatter.
Tụkwasị na nke ahụ, iji eriri ikuku CO2 gas na-agbado ọkụ nwere ike ibelata spatter ịgbado ọkụ, na spatter ịgbado ọkụ na-emepụta site na flux-cored welding waya bụ ihe dịka 1/3 nke waya ịgbado ọkụ siri ike.
5. Njikwa nkuku ọkụ ịgbado ọkụ:
Mgbe ọwa ịgbado ọkụ bụ perpendicular na weldment, a na-emepụta obere spatter ịgbado ọkụ, ma ka akụkụ nke ọchịchọ ahụ dị ukwuu, ka ọ na-agbasawanye. Mgbe ị na-agbado ọkụ, akụkụ ọchịchọ nke ọkụ ịgbado ọkụ ekwesịghị gafere 20º.
