Uila Uila Uila maualalo Electrode
J707
GB/T E7015-D2
AWS E10015-D2
Fa'amatalaga: O le J707 o se eletise u'amea maualuga-maualalo fa'atasi ma le pa'u sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletise lelei), ma e mafai ona uelo i tulaga uma.Pe a manaʻomia, e mafai ona faʻamafanafanaina faʻamaʻi aʻo leʻi faʻapipiʻiina ma faʻafefe pe a uma ona faʻafefe.
Fa'aoga: Fa'aaogaina mo le ueloina 15MnMoV, 14MnMoVB, 18MnMoNb ma isi fausaga u'amea maualalo.O le fausaga uelo e mafai ona galue i lalo o le tulaga o le uelo poʻo le faʻafefe (500 ~ 650 ℃).
Su'ega vaila'au o u'amea u'amea(%):
| C | Mn | Si | Mo | S | P |
Fa'amaonia | ≤0.15 | 1.65 ~ 2.00 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.040 |
Tofotofoina | 0.073 | 1.68 | 0.54 | 0.40 | 0.011 | 0.018 |
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) -30℃ |
Fa'amaonia | ≥690 | ≥590 | ≥15 | ≥27 |
Tofotofoina | 720 | 610 | 18.6 | — |
Fa'asalalauina o le hydrogen i totonu o le uamea ua teuina: ≤4.0mL/100g (auala glycerin)
Asiasiga X-ray: Ou te togi
Fautuaina le taimi nei:
(mm) u'amea lautele | 2.5 | 3.2 | 4.0 | 5.0 |
(A) Uelo Uila | 60 ~ 100 | 100 ~ 140 | 140 ~ 190 | 190 ~ 250 |
Fa'aaliga:
1. E tatau ona tao le electrode mo le 1 itula i le 350 ~ 380 ℃ 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.
