Uila Uila Uila maualalo Electrode
J557SLA, J557SLB
GB/T E5515-G
AWS E8015-G
Fa'amatalaga: Ole sodium maualalo ole hydrogen ufiufi eletise fa'apitoa mo uamea aluminized.Fa'aaoga le DCEP (fa'atonu eletise eletise lelei), ma e mafai ona fa'apipi'i i tulaga uma ma le fa'agaoioiga pu'upu'u.J557SLA e mafai ona faʻapipiʻi saʻo e aunoa ma le aveeseina o le aluminized layer i luga o le togo luga aʻo leʻi faʻapipiʻiina.Ae o le J557SLB e tatau ona aveese le aluminized layer i luga o le togo luga aʻo leʻi faʻapipiʻiina.
Talosaga: E faʻaaogaina mo le faʻapipiʻiina o le fausaga uʻamea aluminized i lalo o le faʻafefe o le hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate ma le hydrogen nitrogen ma le vevela galue i lalo ole 540 ° C.E pei o paipa paipa, mea e faʻamamaina ai le suauʻu, mea faʻapalapala ma paipa ausa, ma isi.
Su'ega vaila'au o u'amea u'amea(%):
| C | Mn | Si | Cr | Mo | Al | S | P |
| ≤0.12 | 0.50 ~ 0.90 | ≤0.50 | ≈0.80 | ≥0.20 | ≤0.055 | ≤0.035 | ≤0.035 |
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) Temp masani. |
| Fa'amaonia | ≥540 | ≥440 | ≥17 | ≥49 |
Fa'asalalauina o le hydrogen i totonu o u'amea teuina: ≤6.0mL/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 | 50 ~ 80 | 80 ~ 110 | 130 ~ 170 | 160 ~ 200 |
Fa'aaliga:
1. E tatau ona tao le eletise mo le 1 itula ile 350 ℃ aʻo leʻi faʻaogaina le faʻaogaina;
2. E taua tele le fa'amamāina o le ele, fua o le suau'u, vai, ma mea leaga i luga o vaega uelo a'o le'i uelo.
