Electrode Uila Uila maualalo vevela
W707
GB/T E5015-G
AWS A5.5 E7015-G
Faʻamatalaga: W707 o se eletise uʻamea maualalo-vevela ma faʻapipiʻi sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletise) ma e mafai ona uelo i tulaga uma.O le u'amea na teuina o lo'o i ai pea le malosi o a'afiaga ile -70°C.
Fa'aoga: Fa'aaogaina mo le ueloina o le sila maualalo vevela pei ole 2.5Ni.
Su'ega vaila'au o u'amea u'amea(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
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) -70℃ |
| Fa'amaonia | ≥490 | ≥390 | ≥22 | ≥27 |
Fa'asalalauina o le hydrogen i totonu o u'amea ua teuina: ≤6.0mL/100g (metotia glycerin) po'o le ≤10mL/100g (mecury po'o le gas chromatography method)
Asiasiga X-ray: Ou te togi
Fautuaina le taimi nei:
| （mm） u'amea lautele | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| （A） Uelo Uila | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Fa'aaliga:
1. E tatau ona tao le electrode mo le 1 itula i le 350 ℃ aʻo leʻi faʻaogaina le faʻaogaina;
2. Taumafai e faʻaaoga le malosi laina laʻititi pe a faʻapipiʻi, faʻapipiʻi faʻapipiʻi ma multi-pass.
