Kedu ụdị ịgbado ọkụ nke flux cored arc dị?
Enwere ụdị abụọ nke flux cored wire arc welding (FCAW-G) yana ịgbado ọkụ nke onwe (FCAW-S), dabere ma ejiri gas mkpuchi mpụga ma ọ bụ na ejighi ya.
Igwe ikuku na-ekpuchi ikuku nke waya flux na-ejikarị carbon dioxide ma ọ bụ carbon dioxide gbakwunyere argon dị ka gas na-echebe, na mmiri na waya nwere obere ihe na-ekpo ọkụ.Usoro a yiri ịgbado ọkụ n'ozuzu gas na-echebe.Ịgbado ọkụ na-echebe onwe ya adịghị mkpa gas nchebe mpụga.Enwere ọnụ ọgụgụ dị ukwuu nke gasifier na ntụgharị, na gas na slag mebiri site na gasifier na-eji maka nchebe.
Kedu uru ọ dị na ịgbado ọkụ na-eme ka flux-cored arc?
Ịgbado ọkụ na-eme ka arc agbụ nwere uru ndị a.
(1) Nnukwu ịgbado ọkụ arụpụta ọrụ dị elu na-agbaze arụmọrụ (ruo 85% ~ 90%), ọsọ agbaze ngwa ngwa;Maka ịgbado ọkụ dị larịị, mkpuchi mkpuchi bụ ugboro 1.5 nke ịgbado ọkụ akwụkwọ ntuziaka, yana maka ọnọdụ ịgbado ọkụ ndị ọzọ, ọ bụ ugboro 3-5 nke ịgbado ọkụ akwụkwọ ntuziaka.
② Obere splash, weld na-akpụ ezigbo ọgwụ isi agbakwunyere arc stabilizer, yabụ nkwụsi ike arc, obere splash, ezigbo weld na-akpụ.N'ihi na ọdọ mmiri a wụrụ awụ jupụtara na slag a wụrụ awụ, ọdịdị elu weld dị mma nke ukwuu karịa nke ịgbado ọkụ carbon dioxide.
(3) Ogo ịgbado ọkụ dị elu N'ihi nchekwa nke slag gas jikọtara ọnụ, ọ nwere ike igbochi gas na-emerụ ahụ nke ọma ịbanye na mpaghara ịgbado ọkụ.Tụkwasị na nke ahụ, ịdị adị nke ọdọ mmiri a wụrụ awụ dị ogologo, nke na-eme ka mmiri ozuzo gas, ya mere weld nwere obere ọdịnaya hydrogen na ezigbo nkwụsị porosity.

Kedu gas nchebe ka a na-ejikarị na mgbado ọkụ nke nwere eriri?Kedu ihe njirimara nke ọ bụla?
Flux cored waya arc ịgbado ọkụ na-ejikarị carbon dioxide gas ma ọ bụ carbon dioxide na argon gas dị ka gas na-echebe.Ọ dị mkpa ịhọrọ ụdị gas dị ka waya flux-cored ejiri mee ihe.
Argon dị mfe ionized, n'ihi ya, ọ dị mfe iji nweta mgbanwe ejection na argon arc.Mgbe ọdịnaya argon nke ngwakọta gas na-erughị 75%, ịgbado ọkụ na-agbado waya nwere ike nweta mgbanwe ụgbọ elu kwụsiri ike.Site na mbelata nke ọdịnaya argon, omimi ntinye na-abawanye, mana nkwụsi ike nke arc na-ebelata na ọnụọgụ spatter na-abawanye.Ya mere, ngwakọta gas kacha mma bụ 75% Ar + 25% CO2.Na mgbakwunye, Ar + 2% O2 nwekwara ike iji maka ngwakọta gas.
Mgbe a na-ahọrọ gas CO2 dị ọcha, ọ ga-agbaze n'okpuru ọrụ nke arc okpomọkụ ma mepụta ọnụ ọgụgụ dị ukwuu nke ikuku oxygen, nke ga-eme ka manganese, silicon na ihe ndị ọzọ dị na ọdọ mmiri a wụrụ awụ, na-eduga na ọkụ nke ihe ndị na-emepụta ihe.Ya mere, ekwesịrị iji waya ịgbado ọkụ nwere nnukwu manganese na silicon.
