Fa'amatalaga: O le J506NiMA ma le J507NiMA o le susū-susua e sili atu le maualalo o le hydrogen-coated low-alloy steel electrodes.O le u'amea teuina e sili ona lelei le palasitika, maualalo le vevela ma le ta'e tete'e, ma e mafai ona uelo i tulaga uma.O le faʻapipiʻi e faʻasaʻo i le faʻafefe o le susu.A maeʻa ona tao le electrode i le 400 ° C x 1h ma paka i totonu o se siʻosiʻomaga ma le susu faʻatusatusa ≥ 80% mo le 4 itula, o loʻo faʻamalieina e le susu o le faʻapipiʻi mea e manaʻomia mo le faʻaaogaina.

Talosaga: E faʻaaogaina mo le faʻapipiʻiina o suauʻu suauu, vaʻa, vaʻa mamafa, ma isi fausaga e faia iuamea kaponi ma uamea uamea maualalo.

Fa'aaliga:

1. E tatau ona tao le electrode mo le 1 itula i le 350 ~ 400 ℃ aʻo leʻi faʻaogaina le faʻaogaina;

2. E taua tele le fa'amamāina o le ea, fua o le suau'u, vai, ma mea leaga i luga o vaega uelo a'o le'i u'uina;

3. Fa'aaoga le fa'agaioiga pu'upu'u pe a uelo.O le ala uelo vaapiapi e talafeagai.
