Yakaderera Alloy Steel Welding Electrode
J556Fe
GB/T E5518-G
AWS E8018-G
Tsanangudzo: J556fe inonzi low alloy steel electrode ine iron powder uye yakaderera hydrogen coating.Ose ari maviri AC neDC anogona kushandiswa, uye anogona kusungirirwa munzvimbo dzese.
Chishandiso: Inoshandiswa kukwenenzvera svikiro kabhoni simbi uye yakaderera alloy simbi zvimiro seQ390.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Si | S | P |
| ≤0.12 | ≥1.00 | ≤0.80 | ≤0.035 | ≤0.035 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % | Impact value (J) -40 ℃ |
| Guaranteed | ≥540 | ≥440 | ≥17 | ≥27 |
Diffusion hydrogen zvemukati mesimbi yakaiswa: ≤10.0mL/100g (mercury kana gasi chromatography nzira)
X-ray kuongorora: Ini giredhi
Yazvino inokurudzirwa:
| (mm) Tsvimbo dhayamita | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 70 ~ 110 | 100 ~ 140 | 140 ~ 170 | 190 ~ 240 |
Cherechedza:
1. Iyo electrode inofanira kubikwa kweawa imwe pa 350 ℃ isati yaitwa welding;
2. Zvinokosha kuchenesa ngura, chikero chemafuta, mvura, netsvina pazvikamu zvinokandwa musati maveld;
3. Shandisa pfupi arc oparesheni kana welding.Iyo yakamanikana welding track yakakodzera.
