I-aluminium ehlanzekile iyinsimbi ethambile futhi edonsa kahle.Ezimweni eziningi, amandla ayo aphansi.Ukwandisa amandla e-aluminium, izakhi ze-alloying zidinga ukungezwa.Ithusi, i-silicon, i-manganese, i-magnesium, ne-zinc kusetshenziswa njengesakhi esiyinhloko ukuze kudlale umphumela wokuqinisa oncibilikayo.I-aluminium ne-aluminium alloy isetshenziswe kabanzi ezimbonini eziningi.
Ukushisela kwe-aluminium ne-aluminium alloy kunzima kakhulu kunensimbi ye-low-carbon steel.Izici zayo zokushisela zihlukile kune-low-carbon steel.Ukusebenza okuqondile kungokulandelayo:
1. I-Soferality ye-welded yokuxhuma ukusebenza kwemishini, yehla ukumelana nokugqwala.
2. Umsebenzi wamakhemikhali unamandla kakhulu, futhi ingaphezulu lakheka kalula.
3. I-conductivity eqinile yokushisa, futhi kulula ukubangela into engancibiliki ngesikhathi sokushisela.
4. Amaphutha alandelanayo njengama-pores, imifantu, imiphetho yokuluma, i-slag kanye nokwakheka kwe-weld.
5. I-coefficient yokwandisa umugqa omkhulu (cishe izikhathi ezi-2 kune-low-carbon steel), ethambekele ekujikeni nasekushintsheni ngesikhathi sokushisela.
6. I-conductivity eshisayo inkulu (cishe izikhathi ezi-5 kune-low-carbon steel).Ngesivinini esifanayo sokushisela, okokufaka okushisayo kuphindwe izikhathi ezi-2 kuya kwezi-4 kunensimbi yokushisela.
Ingxubevange ye-aluminium ishiselwe nge-TIG noma i-GMAW.
1.I-Aluminium alloy tig welding
Uma udinga ukuthola i-welding yekhwalithi ephezulu kakhulu, i-Tig welding ngokuvamile iyisinqumo sokuqala.Indlela yenqubo efaneleke kakhulu ukushintshanisa i-TIG welding kanye ne-AC pulse TIG welding.Kunezinzuzo eziningana:
1. Lapho i-welding, izici ze-cathode atomization zingasuswa ngokwazo.
2. Ifomu lokuxhuma alikhawulelwe, indawo engaphezulu ibushelelezi futhi ilungele ukubunjwa.
3. Indawo yokushisela yokugeleza komoya ukupholisa amalunga ukuze kuphole phansi futhi kuthuthukiswe inhlangano nokusebenza.
Ngakho-ke, le nqubo ifaneleka kakhulu embonini ye-aerospace esezingeni eliphezulu futhi ebaluleke kakhulu.Yebo, ukuntula kwayo nakho kusobala kakhulu.Ukusebenza kahle kwe-welding kuphansi, futhi akufanelekile ukukhiqizwa kokusebenza okuphezulu okuphezulu.
1.I-Aluminium ingxubevange ye-GMAW yokushisela
I-Gmaw welding ingene kancane kancane ezimpilweni zethu.Ukuxhumeka kwe-DC reverse kuvame ukusetshenziswa ngesikhathi sokushisela, futhi i-pulse welding nayo ingasetshenziswa.Uma kuqhathaniswa nokushisela kwe-TIG, ukushisela kwe-GMAW kunezinzuzo ezilandelayo:
1. Cishe akukho ukushiswa kwe-oxidative phakathi nenqubo yokushisela, futhi inqubo ilula.
2. Ukukhiqiza okuphezulu kwabasebenzi.
3. Ungathathi izigxobo ze-tungsten, izindleko eziphansi.
Lapho ushisela ku-GMAW, naka amaphuzu alandelayo:
1. Udinga ukusebenzisa ipayipi likasilika elisekelwe epulasitiki, futhi ipayipi lensimbi alikwazi ukusetshenziswa.
2. Intambo yokushisela i-aluminium ithambile futhi ukulethwa kwezintambo kubi.Udinga ukukhetha isondo lokudiliva le-U-shaped groove wire.
3. Sebenzisa i-diameter yangaphakathi yomlomo we-conductive efanele.
4. Ungahlanganyeli izingxenye nge-welding yensimbi ukuze ugweme ukungcola.
I-GMA-A5356 isebenzisa umthelela kusayithi lekhasimende
Le datha yabelana nabasebenzisi abasaqhubeka noma abasazoshiselwa, okusivumela ukuthi sithuthuke emgwaqeni wokushisela i-aluminium alloy.
Imikhiqizo evamile yokuhlinzeka yenkampani yethu imi kanje:
