ʻO ka wehewehe: ʻO Ni307-4 kahi electrode i hoʻokumu ʻia i ka nickel me ka haʻahaʻa-hydrogen sodium coating.E hoʻohana i ka DCEP (direct current electrodemaikaʻi).Loaʻa iā ia ka hana kuʻihewa maikaʻi me ka hoʻopau ʻana i ka arc paʻa, ka liʻiliʻi o ka spatter, maʻalahi ka wehe ʻana i ka slag,

a me ka wili nani.

Hoʻohana: Hoʻohana ʻia ia no ka hoʻopili ʻana o nā nickel-chromium-iron alloys, e like me Ni600, Ni800 / 800H a me nā superalloys like a i ʻole nickel-based superalloys me kahi mahana hana o 900 ° C. Hiki ke hoʻohana ʻia no nā kila wela haʻahaʻa i loaʻa. Ni3% ~ 9%, e like me ASTM A333, A334, A353, A522, Hiki ke hoʻohana ʻia ke kuʻi ʻana o A553 no ka hoʻoheheʻe metala like ʻole ma waena o Mo400, Ni825, ke kila kila a me ke kila kila haʻahaʻa.

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.
