Aluminom ịgbado ọkụ chọrọ ihe pụrụ iche dabara na njirimara ya dị ka nnukwu ikuku thermal na ike oxidation.. Nke a bụ ndakpọ nke ihe ndị dị mkpa a na-eji maka ịgbado ọkụ aluminom:
1. Ihe eji eme ihe
Ịhọrọ metal ndochi kwesịrị ekwesị dị oke mkpa maka ndakọrịta na alloy aluminom, n'ịhụ na ụda welds na-enweghị mgbawa ma ọ bụ adịghị ike. Ọla aluminom na-ejupụtakarị gụnyere:
- 4043 Alloy (Al-Ee): A na-ejikarị ya eme ihe n'ihi njirimara mgbawa ya dị mma na nkwụsị mgbape dị mma. Ọ dị mma maka ịgbado ọkụ 6xxx usoro aluminum alloys mana akwadoghị ebe achọrọ anodizing na-esote n'ihi ikike maka mpaghara weld gbara ọchịchịrị..
- 5356 Alloy (Al-Mg): Na-enye ike tensile dị ukwuu yana ike siri ike karịa 4043. Ọ na-eguzogide corrosion ma dabara adaba maka ịgbado ọkụ 5xxx usoro alloys. Ọ dabara na agba nke isi metal ka mma mgbe anodizing.
- 5183, 5556 (Al-Mg): A na-eji maka welds ike dị elu tụnyere 5356. Ha na-enye ezigbo nguzogide corrosion na gburugburu mmiri.
- 5554, 5654 (Al-Mg): Ụdị dị iche iche nwere ihe ndị a kapịrị ọnụ maka gburugburu na-enwekarị nchekasị-corrosion.
- 4047 Alloy (Al-Ee): Nwere silicon karịa, ibelata ebe mgbaze na ịba ụba mmiri nke ọdọ mmiri weld, a na-ejikarị eme ihe maka ngwa na-achọ ezigbo ntinye n'ime nkwonkwo.
2. Gases na-echebe
Nhọrọ nke ọma nke nchekwa gas dị oke mkpa iji kpuchido mpaghara weld site na mmetọ ikuku yana iji mee ka arc ahụ kwụsie ike.. Gasị ndị nkịtị gụnyere:
- Argon: Nke a na-ejikarị ekpuchi gas maka aluminum ịgbado ọkụ n'ihi na ọ na-enyere aka ịmepụta arc kwụsiri ike ma belata ọrụ nhicha, nke na-achọsi ike mgbe ịgbado ọkụ aluminum.
- Ngwakọta Helium ma ọ bụ Helium-Argon: A na-eji ihe ndị a na-amụba ntinye na weld ọdọ mmiri fluidity, karịsịa bara uru na thicker ngalaba. Helium na-enyere aka ịmepụta arc dị ọkụ, nke nwere ike ịba uru n'ihi nnukwu ọkụ ọkụ aluminom.
3. Usoro ịgbado ọkụ kpọmkwem ihe
Dabere na usoro ịgbado ọkụ, ihe ndị ọzọ nwekwara ike ịdị mkpa:
- ịgbado ọkụ TIG:
- Electrodes: Na-emekarị, A na-eji tungsten tungsten dị ọcha ma ọ bụ zirconiated tungsten electrodes maka ịgbado ọkụ AC TIG nke aluminom.
- Igwe ịgbado ọkụ AC: Nhọrọ ọzọ dị mkpa ka ọ na-enyere aka imebi oyi akwa oxide nke na-etolite n'elu aluminom.
- MIG ịgbado ọkụ:
- Welding waya: A na-ejikarị waya dị ka ER4043 ma ọ bụ ER5356 na spools wee nye ya nri site na egbe ịgbado ọkụ..
- egbe Spool ma ọ bụ Push-Pull egbe: Ndị a dị oke mkpa iji gbochie nsogbu inye waya n'ihi ịdị nro nke waya aluminom.
4. Ngwa Nkwadebe Elu
A ghaghị ihicha elu aluminom nke ọma tupu ịgbado ọkụ iji wepụ oyi akwa oxide na ihe ọ bụla na-emerụ emerụ:
- ahịhịa (Igwe anaghị agba nchara): A na-eji asacha elu. Ọ dị mkpa iji brushes na-eji naanị na aluminom iji zere mmetọ.
- Ndị na-ehicha kemịkalụ: Enwere ike iji ihe ngwọta sitere na alkaline ma ọ bụ acid wepụ oxides na mmanụ dị arọ mana a ga-ehichapụrịrị nke ọma iji zere iwebata ihe mmetọ n'ime weld..
5. Ngwa nchekwa
Nyere nchapụta nke arc na ọdịdị dị mma nke uzu ọkụ ịgbado ọkụ aluminom, ngwa nchekwa kwesịrị ekwesị dị oke mkpa:
- Okpu agha ịgbado ọkụ na-agba ọchịchịrị: Na-echebe anya pụọ na ọkụ UV siri ike.
- Ndị na-eku ume: Karịsịa mgbe ị na-agbado ọkụ n'ime oghere, iji chebe megide ikuru uzuzu ọjọọ.
- Uwe mkpuchi: Iji kpuchido ọkụ na mkpughe UV.
Using these specific materials correctly can greatly improve the quality of aluminom welds and ensure the structural integrity and longevity of the welded joints.
