Low otutu Irin Welding Electrode
W607
GB/T E5015-G
Aws A5.5 E7015-G
Apejuwe: W607 jẹ elekiturodu irin-iwọn otutu ti o ni iwọn kekere-hydrogen iṣuu soda.Lo DCEP (taara ti isiyi elekiturodu rere) ati ki o le welded ni gbogbo awọn ipo.Irin ti a fi silẹ ni ipa lile to dara ni -60°C.
Ohun elo: Ti a lo fun alurinmorin irin iwọn otutu kekere bii 09MnD.
Apapọ kemikali ti irin weld (%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤0.020 | ≤0.025 |
Awọn ohun-ini ẹrọ ti irin weld:
| Ohun elo idanwo | Agbara fifẹ Mpa | Agbara ikore Mpa | Ilọsiwaju % | Iye ipa (J) -60℃ |
| Ẹri | ≥490 | ≥390 | ≥22 | ≥27 |
Akoonu hydrogen tan kaakiri ti irin ti a fi silẹ: ≤6.0mL/100g (ọna glycerin) tabi ≤10mL/100g (Makiuri tabi ọna chromatography gaasi)

Akiyesi:
1. Awọn elekiturodu gbọdọ wa ni ndin fun 1 wakati ni 350 ℃ ṣaaju ki o to alurinmorin isẹ;
2. O jẹ pataki lati nu soke ipata, epo asekale, omi, ati impurities lori alurinmorin awọn ẹya ara ṣaaju ki o to alurinmorin;
3. Apakan ti a fi wewe le jẹ preheated ni iwọn 150 ° C ṣaaju alurinmorin lati dena awọn dojuijako.
