Ihe dị iche n'etiti ịgbado ọkụ nkịtị MIG/MAG na CO2 ịgbado ọkụ
Njirimara nke ịgbado ọkụ CO2 bụ: ọnụ ala dị ala na nrụpụta nrụpụta dị elu. Agbanyeghị, ọ nwere ọghọm nke nnukwu spatter na ịkpụzi adịghị mma, yabụ ụfọdụ usoro ịgbado ọkụ na-eji ịgbado ọkụ MIG/MAG nkịtị. MIG/MAG ịgbado ọkụ nkịtị bụ usoro ịgbado ọkụ nke arc na-echebe site na inert gas ma ọ bụ gas argon bara ụba, mana ịgbado ọkụ CO2 nwere akụrụngwa oxidizing siri ike, nke na-ekpebi ọdịiche na njirimara nke abụọ ahụ. E jiri ya tụnyere CO2 ịgbado ọkụ, isi uru nke MIG/MAG welding bụ ndị a:
1) A na-ebelata ego nke splash karịa 50%. Akụ ịgbado ọkụ n'okpuru nchebe nke argon ma ọ bụ argon bara ụba gas kwụsiri ike. Ọbụghị naanị na arc kwụsiri ike n'oge mgbanwe droplet na mgbanwe jet, kamakwa n'ọnọdụ mgbanwe dị mkpụmkpụ nke ịgbado ọkụ MAG dị ugbu a, arc nwere obere mmetụta na-asọ oyi na ụmụ irighiri mmiri, si otú a na-ahụ na MIG / Ọnụ ọgụgụ nke spatter kpatara. MAG ịgbado ọkụ obere sekit mgbanwe na-ebelata ihe karịrị 50%.
2) The ịgbado ọkụ onuete na evenly kpụrụ na mara mma. Ebe mbufe nke MIG/MAG welding droplets bụ otu, dị aghụghọ, ma kwụsie ike, a na-emepụta weld ahụ n'otu n'otu na ọmarịcha.
3) Nwere ike weld ọtụtụ arụ ọrụ ọla na ha alloys. Ngwongwo oxidizing nke ikuku ikuku na-esighi ike ma ọ bụ ọbụna na-adịghị eme ya.

4) Ukwuu mma ịgbado ọkụ processability, ịgbado ọkụ àgwà na mmepụta arụmọrụ.
Ọdịiche dị n'etiti pulse MIG/MAG ịgbado ọkụ na nkịtị MIG/MAG ịgbado ọkụ
Ụdị mbufe droplet nke nkịtị MIG/MAG ịgbado ọkụ bụ mbufe jet na elu ugbu a na obere okirikiri mbufe na ala ugbu a. Ya mere, ala ugbu a ka nwere ọghọm nke nnukwu ego nke spatter na adịghị mma ịkpụzi, karịsịa ụfọdụ arụ ọrụ ọla enweghị ike welded n'okpuru ala ugbu a. Welding dị ka aluminum na alloys, igwe anaghị agba nchara, wdg Ya mere, pulsed MIG / MAG ịgbado ọkụ pụtara. Njirimara mbufe droplet ya bụ na usu ọ bụla dị ugbu a na-ebufe otu droplet. N'ezie, ọ bụ nnyefe droplet. E jiri ya tụnyere MIG/MAG welding nkịtị, njirimara ya bụ ndị a:
1) Ụdị kacha mma nke mbufe droplet maka pulse MIG / MAG ịgbado ọkụ bụ ịnyefe otu droplet kwa pulse. N'ụzọ dị otú a, site n'ịgbanwe ugboro ugboro pulse, ọnụ ọgụgụ nke ụmụ irighiri mmiri na-ebufe kwa nkeji oge nwere ike ịgbanwe, nke bụ agbaze ọsọ nke ịgbado ọkụ waya.
2) N'ihi mbufe droplet nke otu pulse na otu dobe, dayameta nke droplet na-adaba na dayameta nke waya ịgbado ọkụ, ya mere okpomọkụ arc nke droplet dị ala, ya bụ, okpomọkụ nke droplet dị ala. (tụnyere mbufe ụgbọ elu na nnukwu nnyefe droplet). Ya mere, ọnụọgụ na-agbaze nke waya ịgbado ọkụ na-abawanye, nke pụtara na a na-emeziwanye arụmọrụ nke ịgbado ọkụ.
3) N'ihi na okpomọkụ nke droplet dị ala, ọkụ ịgbado ọkụ na-adị ntakịrị. Nke a n'otu aka na-ebelata mfu ọkụ nke alloy ihe na n'aka nke ọzọ mma na-ewu gburugburu ebe obibi.
E jiri ya tụnyere ịgbado ọkụ MIG/MAG nkịtị, uru ya bụ ndị a:
1) Welding spatter bụ obere ma ọ bụ ọbụna ọ dịghị spatter.
2) The arc nwere ezigbo directivity ma dabara maka ịgbado ọkụ n'ọnọdụ niile.
3) A na-emepụta weld nke ọma, obosara na-agbaze bụ nnukwu, njirimara ntinye mkpịsị aka dị ka mkpịsị aka na-ada mbà, na ịdị elu fọdụrụnụ dị obere.
4) Obere ugbu a nwere ike weld ọla arụ ọrụ (dịka aluminom na alloys ya, wdg).
Mgbasawanye nso ugbu a nke MIG/MAG welding jet nyefe. N'oge ịgbado ọkụ pulse, ịgbado ọkụ ugbu a nwere ike nweta nnyefe droplet kwụsiri ike site n'akụkụ dị oke egwu nke mbufe ụgbọ elu gaa n'ụdị dị ugbu a nke iri puku amps.
Site na nke dị n'elu, anyị nwere ike ịmata njirimara na uru nke pulse MIG / MAG, ma ọ dịghị ihe nwere ike zuru oke. E jiri ya tụnyere MIG/MAG nkịtị, adịghị ike ya bụ ndị a:
