Low Alloy Irin Welding Electrode
J556Fẹ
GB/T E5518-G
Aws E8018-G
Apejuwe: J556fe jẹ elekiturodu irin alloy kekere pẹlu erupẹ irin ati ideri hydrogen kekere.Mejeeji AC ati DC le ṣee lo, ati ki o le ti wa ni welded ni gbogbo awọn ipo.
Ohun elo: Lo fun alurinmorin alabọde erogba irin ati kekere alloy irin ẹya bi Q390.
Apapọ kemikali ti irin weld (%):
| C | Mn | Si | S | P |
| ≤0.12 | ≥1.00 | ≤0.80 | ≤0.035 | ≤0.035 |
Awọn ohun-ini ẹrọ ti irin weld:
| Ohun elo idanwo | Agbara fifẹ Mpa | Agbara ikore Mpa | Ilọsiwaju % | Iye ipa (J) -40℃ |
| Ẹri | ≥540 | ≥440 | ≥17 | ≥27 |
Akoonu hydrogen tan kaakiri ti irin ti a fi silẹ: ≤10.0mL/100g (Makiuri tabi ọna chromatography gaasi)
Ayewo X-ray: Mo ite
Iṣeduro lọwọlọwọ:
| (mm) Opa opin | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Alurinmorin Lọwọlọwọ | 70 ~ 110 | 100 ~ 140 | 140 ~ 170 | 190 ~ 240 |
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. Lo kukuru arc isẹ nigba alurinmorin.Awọn orin alurinmorin dín to dara.
