R107
GB/T E5015-A1
AWS A5.5 E7015-A1
Faʻamatalaga: R107 o se paʻu uʻamea faʻafefe pearlitic ma se paʻu sodium maualalo-hydrogen o loʻo i ai 0.5% Mo. Faʻaaoga le DCEP (faʻaogaina o le eletise o loʻo i ai nei) ma e mafai ona faʻapipiʻiina i tulaga uma. E tatau ona faʻamafanafanaina le uelo i le 90 ~ 110 ℃ aʻo leʻi faʻafefe. .
Talosaga: E faʻaaogaina mo le faʻapipiʻiina o paipa faʻapipiʻi ma le vevela galue i lalo ole 510 ° C (pei o le 15Mo, ma isi), ma e mafai foi ona faʻaaogaina mo le faʻaogaina o le uʻamea lautele maualalo-malosi maualuga.
Su'ega vaila'au o u'amea u'amea(%):
| C | Mn | Si | Mo | S | P |
| ≤0.12 | 0.50~ 0.90 | ≤0.50 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
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 | ≥490 | ≥390 | ≥22 | ≥47 |
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:
| u'amea lautele （mm） | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| UeloI le taimi nei （A） | 40 ~ 70 | 60 ~ 90 | 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. 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.
