Welding aluminium inoda zvimwe zvinhu zvinoenderana neayo chaiwo maitiro senge yakakwira yekupisa conductivity uye kubatwa neoxidation.. Heino kuparara kwezvinhu zvakakosha zvinoshandiswa pakushongedza aluminium:
1. Filler Metals
Kusarudza iyo chaiyo yekuzadza simbi kwakakosha kuti ienderane neiyo base aluminium alloy, kuve nechokwadi mawelds eruzha pasina kutsemuka kana kupera simba. Zvakajairwa aluminium filler simbi dzinosanganisira:
- 4043 Alloy (Al-Hongu): Inoshandiswa zvakanyanya nekuda kweiyo yakanakisa kuyerera maitiro uye yakanaka kuputika kuramba. Yakanakira welding 6xxx akateedzana aruminiyamu alloys asi isingakurudzirwe uko inozotevera anodizing inodiwa nekuda kwekugona kwenzvimbo ine rima weld..
- 5356 Alloy (Al-Mg): Inopa simba rakanyanya kusimba uye kusimba kuri nani pane 4043. Iyo inopesana nekuora uye inokodzera welding 5xxx series alloys. Inoenderanawo nemuvara wesimbi yepasi zviri nani mushure meanodizing.
- 5183, 5556 (Al-Mg): Inoshandiswa kune yakakwirira simba welds zvichienzaniswa 5356. Vanopa kupikisa kwakanaka kune ngura munzvimbo dzegungwa.
- 5554, 5654 (Al-Mg): Variants vane chaivo zvimiro zvenzvimbo dzinowanzoita kusagadzikana-kuora.
- 4047 Alloy (Al-Hongu): Ine silicon yakawanda, kuderedza kunyungudika uye kuwedzera fluidity ye weld pool, kazhinji inoshandiswa kune zvikumbiro zvinoda kuyerera kwakanaka mujoinhi.
2. Kudzivirira Magasi
Kusarudzwa kwakaringana kwekudzivirira gasi kwakakosha kuchengetedza nzvimbo yeweld kubva pakusvibiswa kwemuchadenga uye kudzikamisa arc.. Magasi akajairika anosanganisira:
- Argon: Iyo inonyanya kushandiswa kudzivirira gasi re aluminium welding nekuti inobatsira kuburitsa arc yakagadzikana uye inoderedza kuchenesa chiito, iyo inodiwa kana welding aluminium.
- Helium kana Helium-Argon Misanganiswa: Aya anoshandiswa kuwedzera kupinda uye weld pool fluidity, kunyanya inobatsira muzvikamu zvakakora. Helium inobatsira kugadzira arc inopisa, iyo inogona kubatsira nekuda kwealuminium yakanyanya kupisa conductivity.
3. Welding Process Yakananga Materials
Zvichienderana nekugadzira welding, zvimwe zvinhu zvinogonawo kudikanwa:
- TIG Welding:
- Electrodes: Kazhinji, tungsten yakachena kana zirconiated tungsten electrodes anoshandiswa kune AC TIG welding yealuminium.
- AC Welding Machines: Alternating current yakakosha sezvo ichibatsira kutyora iyo oxide layer inoumba pane aluminum.
- MIG Welding:
- Welding Wire: Waya dzakaita seER4043 kana ER5356 dzinowanzo shandiswa pa spools uye kudyiswa kuburikidza nepfuti yewelding..
- Spool Pfuti kana Push-Dhonza Pfuti: Izvi zvakakosha kudzivirira matambudziko ekudyisa waya nekuda kwekupfava kwewaya dzealuminium.
4. Zvishandiso Zvekugadzirira Pamusoro
Nzvimbo dzeAluminium dzinofanirwa kunyatsocheneswa pamberi pewelding kubvisa oxide layer uye chero zvinosvibisa:
- Brushes (Simbi isina ngura): Inoshandiswa kukwesha pamusoro. Zvakakosha kushandisa mabhurashi anongoshandiswa paaluminium kudzivirira kusvibiswa.
- Chemical Cleaners: Alkaline kana acid-based solutions inogona kushandiswa kubvisa heavy oxides neoiri asi inofanira kunyatsocheneswa kudzivirira kupinza zvinosvibisa mukati meweld..
5. Safety Equipment
Tichifunga kupenya kwearc uye kunaka kwakanaka kwealuminium welding fumes, giya rekuchengetedza rakakodzera rakakosha:
- Auto-kusviba Welding Helmet: Inodzivirira maziso kubva kune yakanyanya UV mwenje.
- Mafemero: Kunyanya kana welding munzvimbo dzakavharirwa, kudzivirira kufema utsi hunokuvadza.
- Zvipfeko Zvokudzivirira: Chengetedza kubva pachirimo uye kuratidzwa kweUV.
Using these specific materials correctly can greatly improve the quality of aluminium welds and ensure the structural integrity and longevity of the welded joints.
