ʻElekode Kuʻihao Nickel a me Nickel Alloy

Ni307-7                                                     

GB/T ENi6152

AWS A5.11 ENiCrFe-7

Wehewehe: ʻO Ni307-7 kahi electrode 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 weld nani. Loaʻa i ka metala i waiho ʻia nā waiwai mechanical paʻa a me ke kūpaʻa maikaʻi i ka palahonā lewa hoʻomakeʻe wela kiʻekiʻe a me nā lewa i loaʻa ka sulfur.

Noi: Hoʻohana ʻia i loko o ka ʻenekinia nukelea, ka waikawa sulfuric, ka waikawa nitric a me nā lako hana hydrogen fluorine, e like me ka nickel 690 alloy, ASTM B166, B167, b168, a pēlā aku, hiki ke hoʻohana ʻia no ka hoʻopili ʻana i ka hao nickel-chromium a me ke kila kila a me ka hoʻopili ʻana i nā papa pale corrosion ma ke kila.

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.
