Aluminum walda wata babbar fasaha ce a masana'antu daban-daban, daga mota zuwa sararin sama, saboda rashin nauyi na aluminum da kaddarorin juriya. Duk da haka, walda aluminium yana haifar da ƙalubale na musamman saboda ƙarfin ƙarfin zafinsa da ƙarancin narkewa. Wannan blog ɗin zai jagorance ku ta hanyar mahimman abubuwan yadda ake walda aluminum, ba da haske game da shawo kan ƙalubalen gama gari da samun ƙarfi, m welds.
Fahimtar Aluminum Welding
Kafin nutsewa cikin ƙayyadaddun abubuwan walda na aluminum, yana da mahimmanci don fahimtar kaddarorin aluminum waɗanda ke shafar haɓakar sa:
- High thermal Conductivity: Aluminum yana gudanar da zafi da sauri, wanda ke nufin zai iya watsar da zafi daga yankin walda da sauri. Wannan yana buƙatar ƙarin abubuwan zafi yayin walda idan aka kwatanta da karfe.
- Ƙananan Narkewa: Aluminum alloys narke a kusa da 600 ° C, kasa da karfe. Wannan na iya haifar da babban haɗarin ƙonawa idan ba a kula ba.
- Oxide Layer: Aluminum a zahiri yana samar da Layer oxide wanda ya fi girma a wurin narkewa fiye da ƙarfen da ke ƙasa. Wannan Layer yana buƙatar cirewa don nasarar walda.
Zaɓan Hanyar Walƙiya Dama
Hanyoyi na yau da kullun don walda aluminum sune Gas Tungsten Arc Welding (GTAW, ya da TIG) da Gas Metal Arc Welding (GMAW, ya da MIG). Ga yadda suke kwatanta:
- TIG Welding: Mafi dacewa don kayan bakin ciki da lafiya, cikakken aiki. Yana ba mai walda mafi girma iko akan walda fiye da sauran hanyoyin, yin shi cikakke ga high quality-, daidai welds.
- Farashin MIG: Mafi dacewa ga guntun aluminum masu kauri da saurin walda. Gabaɗaya ya fi sauƙi don koyo da ƙarin gafara fiye da TIG, ko da yake yana iya zama ƙasa da madaidaici.
Kayan aiki da Shirye-shirye
Don farawa aluminum waldi, za ku buƙaci kayan aiki masu dacewa. Domin TIG waldi, za ku buƙaci:
- AC mai iya TIG welder
- Ƙarfin farawa mai girma-mita
- Tungsten mai tsabta ko zircononiated tungsten lantarki
- Argon garkuwar gas
- Madaidaicin kayan cikawa, 4043 gami (Al- iya) kuma 5356 gami (Al-Mg) ana yawan amfani da karafa na filler
Don walda MIG:
- A MIG welder tare da tsarin tuƙi mai dacewa da aluminium
- Argon ko argon-helium mix don kariya ga gas
- Bindigar spool ko bindigar turawa don hana matsalar ciyar da waya
Shiri yana da mahimmanci lokacin walda aluminum. Tsaftace kayan sosai don cire kowane mai, datti, kuma musamman oxide Layer. Cire injina (goga karfe) ko za a iya amfani da hanyoyin sinadarai don tabbatar da cewa aluminum ba ta da gurɓatacce kafin ka fara.
Don ƙarin bayani akan walda aluminium, don Allah koma zuwa ‘Aluminum Welding: Jagora Mai Aiki‘
Dabarun walda
- Preheating: Dangane da kauri da nau'in aluminum, preheating zai iya taimakawa wajen sarrafa zafi da kuma guje wa murdiya ta thermal.
- Fasahar Turawa: Lokacin walda MIG, amfani da dabarar turawa, Inda fitilar ta karkata zuwa wajen walda, tura kududdufin tare. Wannan yana ba da mafi kyawun ɗaukar iskar gas da walda mai tsabta.
- Gudanar da Puddle: Ruwan Aluminum yana nufin sarrafa kududdufin walda yana da mahimmanci. Yi hankali ga girman walƙiyar walƙiya da halin ɗabi'a, daidaita saurin ku da ƙarfin ku daidai.
Magance Matsalolin gama gari
- Porosity: Ana iya haifar da hakan ta hanyar gurɓatawa, iskar garkuwa ba daidai ba, ko danshi mai yawa. Tabbatar cewa komai ya bushe kuma yana amfani da nau'in gas daidai da adadin gas.
- Fatsawa: Aluminum yana da saurin fashewa, musamman a karshen walda. Don hana hakan, tabbatar da haɗin gwiwa an tsara shi da kyau kuma an rigaya kayan aiki idan ya cancanta. Ƙara kayan filler a ƙarshen walda kuma zai iya taimakawa.
- Karya: Saboda da thermal Properties, aluminum na iya jujjuyawa sosai lokacin da aka yi walda. Don yaƙar wannan, yi amfani da shirye-shiryen haɗin gwiwa daidai, kayan aiki, kuma tack waldi don riƙe komai a wurin.
Nade Up
Aluminum walda yana buƙatar fahimtar ƙayyadaddun kaddarorin sa da daidaita dabarun ku don ɗaukar su. Tare da aiki, kayan aiki masu dacewa, da tsarin shiri sosai, za ka iya ƙware da fasahar walda aluminum, yin komai daga gyare-gyare mai sauƙi zuwa hadaddun majalisai mai yiwuwa. Ko kun zaɓi hanyoyin TIG ko MIG, Hakuri da daidaito za su kai ku zuwa ga nasara da ƙarfi mai ƙarfi a cikin wannan ƙalubale amma mai lada.
