Nikeli ma le nikeli u'umea fa'aeletise
Ni327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
Faʻamatalaga: Ni327 -6 o se eletise faʻavae nickel ma le paʻu sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletiselelei).O le u'amea ua teuina e sili ona lelei le palasitika, ma'a'a ma le ta'e.Uamea teuina o loʻo i ai le faʻalauteleina o le laina tutusa e tutusa ma le uʻamea, ma e maualuga le malosi ma le malosi o le pala i le vevela o le potu ma le maualuga o le vevela.
Talosaga: E faʻaaogaina mo le faʻapipiʻiina o le uʻamea Ni9%, ma e mafai foi ona faʻaogaina mo le faʻaogaina o uʻamea eseese ma mea faigata-e-weld alloys.

Fa'aaliga:
1. E tatau ona tao le eletise mo le 1 itula ile 300 ℃ aʻo leʻi faʻaogaina le faʻaogaina.Taumafai e fa'aoga se arc pupuu e uelo;
2. E taua tele le fa'amamāina o le ea, suau'u, vai, ma mea leaga i luga o vaega uelo a'o le'i uelo.
3. Taumafai e faʻaaoga le malosi o le laina laʻititi pe a faʻapipiʻi, faʻapipiʻi faʻapipiʻi ma multi-pass.
