ʻO ka wehewehe: ʻO Ni307-2 kahi electrode nickel-based me ka haʻahaʻa-hydrogen sodium coating.E hoʻohana i ka DCEP (direct current electrode positive).No ka mea he nui ka molybdenum, niobium a me nā mea hoʻohui ʻē aʻe i ka weld, ʻoi aku ka maikaʻi o ka pale ʻana i ka metala i waiho ʻia.

Hoʻohana: Hoʻohana ʻia no ka wiliwili ʻana i nā nickel-chromium-iron alloys (e like me UNS N08800, UNS N06600), kūpono loa no ka hoʻopili ʻana i nā metala like ʻole, ka hoʻololi ʻana i ka papa kuʻi a me ka hoʻoheheʻe ʻana i luna, a hiki ke hoʻohana ʻia ke hoʻohana ʻia ka mahana hana he 980 ° C, akā hiki iā ia ke pale aku i ka oxidation ke kiʻekiʻe ka mahana ma mua o 820 ° C Hoʻemi i ka wahine a me ka ikaika.

ʻO ka hui kemika o ka weld metala(%):

Nā waiwai mīkini o ka weld metala:

Manaʻo ʻia i kēia manawa:

Hoʻolaha:

1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma kahi o 300 ℃ ma mua o ka hana wili;

2. Pono pono e hoʻomaʻemaʻe i ka ʻōpala, ka ʻaila, ka wai, a me nā haumia ma nā ʻāpana wili ma mua o ka wili ʻana.E ho'āʻo e hoʻohana i kahi pōkā pōkole e wili.
