Tsanangudzo: J707Ni inonzi low-alloy high-strength steel electrode ine yakaderera-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka) uye inogona kusungirirwa munzvimbo dzese.Deposited metal ine yakanaka mechanical properties.Kuenzaniswa neJ707 electrode, chinhu chikuru cheJ707Ni ndechekuti iyo yakaderera tembiricha kuoma uye kutsemuka kuramba kwakavandudzwa zvakanyanya.
Chikumbiro: Inoshandiswa pakushongedza yakaderera-alloy yakakwirira-yakasimba simbi zvivakwa zveanoenderana masimba masimba, akadai se14MnMoVB, WEL-TEN70 uye Japanese HW56 uye mamwe akaderera-alloy yakakwirira-simba simbi zvimiro.
Kemikari yakagadzirwa nesimbi weld (%):

Cherechedza:
1. Iyo electrode inofanira kubikwa kweawa imwe pa 350 ~ 380 ℃ 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.
