Yakaderera Alloy Steel Welding Electrode
J707RH
GB/T E7015-G
AWS E10015-G
Tsanangudzo: J707RH ndeyekusimba kwepamusoro-yakaderera hydrogen electrode ine yakaderera hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka) uye inogona kusungirirwa munzvimbo dzose.The welding process performance yakanaka.Iyo inotonhora yekukotama, kutsemuka kuramba uye kuputika kuramba kwemajoini akaiswa zvakanaka.Deposited metal ine purasitiki yakakura uye kuoma.
Chikumbiro: Inoshandiswa pakuputira zvivakwa zvehull, uye yakakodzerawo kusungirirwa kwezvivakwa zvakakosha zveRp0.2≥590MPa yakakwirira-simba simbi.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Cr | Si | Ni | Mo | S | P | S + P |
| ≤0.10 | 1.20 ~ 1.60 | 0.08 ~ 0.20 | 0.30 ~ 0.60 | 1.40 ~ 2.00 | 0.25 ~ 0.50 | ≤0.020 | ≤0.020 | ≤0.035 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % | Impact value (J) -50 ℃ |
| Guaranteed | ≥690 | ≥590 | ≥15 | ≥34 |
Diffusion hydrogen yemukati mesimbi yakaiswa: ≤4.1mL/100g (mercury kana gasi chromatography nzira)
X-ray kuongorora: Ini giredhi
Yazvino inokurudzirwa:
| (mm) Tsvimbo dhayamita | 4.0 | 5.0 |
| (A) Welding Current | 160 ~ 180 | 180 ~ 220 |
Cherechedza:
1. Iyo electrode inofanira kubikwa kweawa 2 pa400 ℃ 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.
