O a auala o le fa'againa ma le fa'atupu?

Metotia o le fausiaina:

 

① Tatala fa'amauina (fa'atau fua)

 

E aofia ai ituaiga e tolu: palapala oneone susu, palapala oneone mago, ma eleele oneone fa'ama'a'a kemikolo;

 

② Tapuni faiga fa'ailoga

 

Tu'u fa'apitoa e fa'aaoga ai le oneone fa'alenatura ma iliili e fai ma mea fa'apipi'i autu (e pei o le fa'auluina o tupe, fa'alupe palapala, fa'a'a'oa'oga fa'aa'oa'oga fa'ameamea, fa'amalo fa'aleaga, fa'amalo malo, fa'ameamea, ma isi);

 

③ O isi auala fa'avasegaga fa'apala

 

E tusa ai ma le vevela deformation, forging e mafai ona vaevaeina i le vevela vevela (faʻagaioiga vevela e maualuga atu nai lo le recrystallization vevela o le uʻamea pili), mafanafana mafanafana (i lalo ifo o le recrystallization vevela), ma malulu forging (i le potu vevela).
