AWS E10015-G High Toughness Ultra-Low Hydrogen Electrode J707RH Low Alloy Steel Weld Rod

Haʻahaʻa Alloy Steel Weld Electrode

J707RH                               

GB/T E7015-G

AWS E10015-G

Hōʻike: J707RH he kiʻekiʻe ka ikaika ultra-low hydrogen electrode me ka haʻahaʻa hydrogen sodium coating.E hoʻohana i ka DCEP (direct current electrode positive) a hiki ke welded ma nā kūlana a pau.He maikaʻi ke kuʻi anu, ka māwae a me ka pahū o nā hui welded.ʻO ka metala i waiho ʻia he plasticity nui a paʻakikī.

Hoʻohana: Hoʻohana ʻia ia no ka hoʻopili ʻana i nā hale hull, a kūpono hoʻi no ka hoʻopili ʻana i nā hale koʻikoʻi o Rp0.2≥590MPa ke kila ikaika kiʻekiʻe.

ʻO ka hui kemika o ka weld metala(%):

Nā waiwai mīkini o ka weld metala:

Maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤4.1mL/100g (mercury a i ʻole gas chromatography method)

X-ray inspection: I ka helu

Manaʻo ʻia i kēia manawa:

Hoʻolaha:

1. Pono e hoʻomoʻa ʻia ka electrode no 2 hola ma 400 ℃ ma mua o ka hana wili;

2. He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka aila unahi, ka wai, a me nā haumia ma nā ʻāpana wili ma mua o ka wili ʻana;

3. E hoʻohana i ka hana pōkole i ka wā e wili ai.Pono ke ala wiliwili haiki.
