ʻO ka wehewehe ʻana: J506NiMA a me J507NiMA nā mea hoʻoheheʻe haʻahaʻa haʻahaʻa haʻahaʻa i hoʻopili ʻia e ka hydrogen.ʻO ka metala i hoʻopaʻa ʻia he plasticity maikaʻi loa, haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūʻē ʻana, a hiki ke welded ma nā kūlana āpau.Kūleʻa ka uhi ʻana i ka hoʻomaʻamaʻa ʻana.Ma hope o ka hoʻomoʻa ʻia ʻana o ka electrode ma 400 ° C x 1h a kau ʻia i kahi kaiapuni me kahi haʻahaʻa haʻahaʻa ≥ 80% no 4 mau hola, e hoʻokō mau ana ka moisture content o ka uhi i nā koi no ka hoʻohana.

Hoʻohana: Hoʻohana ʻia ia no ka hoʻopili ʻana i nā paepae aila, nā moku, nā moku kaomi, a me nā hale ʻē aʻe i hana ʻiake kila kalapona a me ke kila haʻahaʻa.

ʻO ka hui kemika o ka weld metala(%):

Nā waiwai mīkini o ka weld metala:

Maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤5.0mL/100g (gas chromatography a i ʻole ke ʻano mercury)

Māmā maʻiʻo o ka electrode coatings: ≤0.30%

X-ray inspection: I ka helu

Manaʻo ʻia i kēia manawa:

Hoʻolaha:

1. Pono e kālua ʻia ka electrode no ka hola 1 ma 350 ~ 400 ℃ ma mua o ka hana kuʻi ʻana;

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.
