Aluminum walda yana buƙatar takamaiman kayan da suka dace da takamaiman kaddarorin sa kamar haɓakar zafin jiki mai ƙarfi da lallausan iskar shaka.. Anan ga rugujewar mahimman kayan da ake amfani da su don walda aluminum:
1. Filler Karfe
Zaɓin ƙarfe mai filler daidai yana da mahimmanci don dacewa tare da madaidaicin alloy na aluminum, tabbatar da sautin walda ba tare da tsagewa ko rauni ba. Ƙarfe na filler na gama gari sun haɗa da:
- 4043 Alloy (Al- iya): An yi amfani da shi sosai saboda kyawawan halaye masu gudana da kuma juriya mai kyau. Yana da manufa don walda 6xxx jerin aluminum gami amma ba a ba da shawarar inda ake buƙatar anodizing na gaba ba saboda yuwuwar yankin walda mai duhu..
- 5356 Alloy (Al-Mg): Yana ba da ƙarfi mafi girma da ƙarfi fiye da 4043. Yana da juriya ga lalata kuma ya dace da walda 5xxx jerin gami. Hakanan ya dace da launi na ƙarfe na tushe mafi kyau bayan anodizing.
- 5183, 5556 (Al-Mg): Ana amfani dashi don mafi girman ƙarfin walda idan aka kwatanta da 5356. Suna ba da kyakkyawar juriya ga lalata a cikin yanayin ruwa.
- 5554, 5654 (Al-Mg): Bambance-bambance tare da ƙayyadaddun kaddarorin don mahalli masu saurin lalacewa-lalata.
- 4047 Alloy (Al- iya): Ya ƙunshi ƙarin siliki, rage narkewa da kuma ƙara yawan ruwa na tafkin walda, sau da yawa ana amfani dashi don aikace-aikacen da ke buƙatar kwarara mai kyau a cikin haɗin gwiwa.
2. Garkuwar Gas
Zaɓin da ya dace na garkuwar gas yana da mahimmanci don kare yankin walda daga gurɓataccen yanayi da kuma daidaita baka.. Gas ɗin gama gari sun haɗa da:
- Argon: Mafi yawan amfani da iskar garkuwa don aluminum waldi saboda yana taimakawa samar da tsayayyen baka kuma yana rage aikin tsaftacewa, wanda ake so a lokacin walda aluminum.
- Helium ko Helium-Argon Mixtures: Ana amfani da waɗannan don ƙara yawan shigar ruwa da walƙiya, musamman amfani a cikin kauri sassa. Helium yana taimakawa wajen samar da baka mai zafi, wanda zai iya zama mai fa'ida saboda tsananin zafi na aluminum.
3. Takamaiman Tsarin walda
Dangane da fasahar walda, sauran kayan na iya zama dole:
- TIG Welding:
- Electrodes: Yawanci, Tungsten tungsten ko zirconiated tungsten lantarki ana amfani dashi don walda AC TIG na aluminum.
- AC walda Machines: Alternating current yana da mahimmanci yayin da yake taimakawa tarwatsa Layer oxide wanda ke samuwa akan saman aluminum.
- Farashin MIG:
- Waya Welding: Wayoyi irin su ER4043 ko ER5356 ana yawan amfani da su akan spools kuma ana ciyar da su ta cikin bindigar walda..
- Bindigan Spool ko Push-Pull Guns: Waɗannan suna da mahimmanci don hana matsalolin ciyar da waya saboda laushin wayoyi na aluminum.
4. Kayayyakin Shiryewar Sama
Dole ne a tsaftace saman aluminium sosai kafin waldawa don cire Layer oxide da duk wani gurɓataccen abu:
- Goge (Bakin Karfe): Ana amfani dashi don goge saman. Yana da mahimmanci a yi amfani da goga waɗanda ake amfani da su kawai akan aluminum don guje wa gurɓatawa.
- Chemical Cleaners: Ana iya amfani da maganin alkaline ko tushen acid don cire manyan oxides da mai amma dole ne a wanke su sosai don guje wa shigar da gurɓataccen abu a cikin walda..
5. Kayayyakin Tsaro
Idan aka yi la'akari da haske na baka da kyawawan yanayin hayakin walda na aluminum, kayan tsaro masu dacewa suna da mahimmanci:
- Kwalkwali Welding mai duhu: Yana kare idanu daga tsananin hasken UV.
- Masu numfashi: Musamman lokacin walda a cikin wuraren da aka kulle, don kariya daga shakar hayaki mai cutarwa.
- Tufafin Kariya: Don kariya daga tartsatsin wuta da bayyanar UV.
Using these specific materials correctly can greatly improve the quality of aluminum welds and ensure the structural integrity and longevity of the welded joints.
