GB/T ENi6093

AWS A5.11 ENiCrFe-4

Wehewehe: ʻO Ni307-4 kahi electrode i hoʻokumu ʻia me ka nickel me ka uhi sodium haʻahaʻa-hydrogen. E hoʻohana i ka DCEP (electrode au pololeimaikaʻi). Loaʻa iā ia ka hana kuʻihao maikaʻi loa me ka puhi ʻana o ke arc paʻa, ka liʻiliʻi o ka spatter, ka wehe maʻalahi ʻana i ka slag,

a me ka wili nani.

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

Ka hoʻohuihui kemika o ka metala i hoʻoheheʻe ʻia (%):

Nā ʻano mechanical o ka metala i hoʻoheheʻe ʻia:

Manaʻo ʻia kēia manawa:

Hoʻolaha:

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

2. He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka ʻaila, ka wai, a me nā mea haumia ma nā ʻāpana kuʻi ma mua o ka kuʻi ʻana. E hoʻāʻo e hoʻohana i kahi ʻāʻī pōkole e kuʻi ai.
