Aluminiomu alurinmorin nilo awọn ohun elo pato ti o baamu awọn ohun-ini rẹ pato gẹgẹbi iṣiṣẹ igbona giga ati ifaragba si ifoyina.. Eyi ni didenukole ti awọn ohun elo pataki ti a lo fun alurinmorin aluminiomu:

1. Awọn irin Filler

Yiyan irin kikun kikun jẹ pataki fun ibamu pẹlu alloy aluminiomu ipilẹ, aridaju ohun welds lai wo inu tabi ailera. Awọn irin kikun aluminiomu ti o wọpọ pẹlu:

• 4043 Alloy (Al-Bẹẹni): Ti a lo jakejado nitori awọn abuda ṣiṣan ti o dara julọ ati resistance kiraki ti o dara. O jẹ apẹrẹ fun alurinmorin 6xxx jara aluminiomu alloys ṣugbọn kii ṣe iṣeduro nibiti o nilo anodizing atẹle nitori agbara fun agbegbe weld dudu.
• 5356 Alloy (Al-Mg): Nfun tobi fifẹ agbara ati ki o dara toughness ju 4043. O jẹ sooro si ipata ati pe o dara fun alurinmorin 5xxx jara alloys. O tun baamu awọ ti irin mimọ dara julọ lẹhin anodizing.
• 5183, 5556 (Al-Mg): Lo fun ti o ga agbara welds akawe si 5356. Wọn pese resistance to dara si ipata ni awọn agbegbe okun.
• 5554, 5654 (Al-Mg): Awọn iyatọ pẹlu awọn ohun-ini kan pato fun awọn agbegbe ti o ni itara si aapọn-ibajẹ.
• 4047 Alloy (Al-Bẹẹni): Ni ohun alumọni diẹ sii, atehinwa yo ojuami ati ki o npo fluidity ti awọn weld pool, nigbagbogbo lo fun awọn ohun elo ti o nilo sisan ti o dara sinu isẹpo.

2. Awọn eefin idabobo

Yiyan deede ti gaasi idabobo jẹ pataki lati daabobo agbegbe weld lati idoti oju-aye ati lati mu arc duro.. Awọn gaasi ti o wọpọ pẹlu:

• Argon: Awọn julọ commonly lo shielding gaasi fun aluminiomu alurinmorin nitori pe o ṣe iranlọwọ fun agbejade aaki iduroṣinṣin ati dinku igbese mimọ, eyi ti o jẹ wuni nigbati alurinmorin aluminiomu.
• Helium tabi Helium-Argon Mixtures: Awọn wọnyi ti wa ni lo lati mu ilaluja ati weld pool fluidity, paapaa anfani ni awọn apakan ti o nipọn. Helium ṣe iranlọwọ lati ṣe agbejade arc ti o gbona, eyi ti o le jẹ anfani nitori iṣiṣẹ ooru giga ti aluminiomu.

3. Ilana alurinmorin Specific elo

Da lori ilana alurinmorin, awọn ohun elo miiran le tun jẹ pataki:

• TIG Welding:
  • Electrodes: Ni deede, Tungsten mimọ tabi awọn amọna tungsten zirconiated ni a lo fun alurinmorin AC TIG ti aluminiomu.
  • AC Welding Machines: Yiyi lọwọlọwọ jẹ pataki bi o ṣe n ṣe iranlọwọ lati fọ Layer oxide ti o dagba lori awọn ipele aluminiomu.
• Iyipada ninu owo-owo MIG:
  • Welding Waya: Awọn okun onirin bii ER4043 tabi ER5356 ni igbagbogbo lo lori awọn spools ati jẹun nipasẹ ibon alurinmorin..
  • Spool ibon tabi Titari-Fa ibon: Iwọnyi jẹ pataki lati ṣe idiwọ awọn iṣoro ifunni waya nitori rirọ ti awọn onirin aluminiomu.

4. Awọn ohun elo Igbaradi Dada

Aluminiomu roboto gbọdọ wa ni ti mọtoto daradara ṣaaju ki o to alurinmorin lati yọ awọn ohun elo afẹfẹ Layer ati eyikeyi contaminants:

• Awọn gbọnnu (Irin ti ko njepata): Lo lati scrub awọn dada. O ṣe pataki lati lo awọn gbọnnu ti a lo lori aluminiomu nikan lati yago fun idoti.
• Kemikali Cleaners: Awọn ojutu ti o da lori alkane tabi acid le ṣee lo lati yọ awọn oxides ti o wuwo ati awọn epo kuro ṣugbọn gbọdọ wa ni ṣan daradara ni pipa lati yago fun iṣafihan awọn idoti sinu weld..

5. Awọn ohun elo aabo

Fi fun imọlẹ ti arc ati ẹda didara ti awọn eefin alurinmorin aluminiomu, Awọn ohun elo aabo ti o yẹ jẹ pataki:

• Àṣíborí alurinmorin-ṣokunkun laifọwọyi: Ṣe aabo awọn oju lati ina UV ti o lagbara.
• Awọn ẹrọ atẹgun: Paapa nigbati alurinmorin ni ihamọ awọn alafo, lati dabobo lodi si simi ipalara eefin.
• Aso Idaabobo: Lati daabobo kuro lọwọ awọn ina ati ifihan UV.

Using these specific materials correctly can greatly improve the quality of aluminiomu welds and ensure the structural integrity and longevity of the welded joints.
