Uila Uila Uila maualalo Electrode
J506NiMA, J507NiMA
GB/T E5016-G E5015-G
AWS E7018-G E7015-G
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.
Su'ega vaila'au o u'amea u'amea(%):

Fa'amaonia | ≤0.12 | ≥1.00 | ≤0.50 | ≤0.60 | ≤0.035 | ≤0.040 |
Tulaga fa'ainisinia o u'amea u'amea:
Su'ega mea | Malosi fa'asa Mpa | Tuuina atu le malosi Mpa | Fa'aumiumi % | Tau a'afiaga (J) -46℃ |
Fa'amaonia | ≥490 | ≥390 | ≥22 | ≥27 |
Fa'asalalauina o mea o lo'o i totonu ole u'amea o lo'o teuina: ≤5.0mL/100g (chromatography kesi po'o metotia mercury)
Susū i totonu o paluga eletise: ≤0.30%
Asiasiga X-ray: Ou te togi
Fautuaina le taimi nei:
u'amea lautele | 2.5 | 3.2 | 4.0 | 5.0 |
Uelo Uila | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
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.
