Nickel and Nickel Alloy Welding Electrode
Ni307-7
GB/T ENi6152
AWS A5.11 ENiCrFe-7
ʻO ka wehewehe: ʻO Ni307-7 kahi electrode nickel-based 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.ʻO ka metala i hoʻopaʻa ʻia i nā waiwai mechanical paʻa a me ke kūpaʻa corrosion maikaʻi i lokonā ea hoʻoheheʻe kiʻekiʻe a me ka sulfur.
Hoʻohana: Hoʻohana ʻia i ka ʻenekinia nuklea, sulfuric acid, nitric acid a me nā mea hana hana hydrogen fluorine, e like me ka nickel 690 alloy, ASTM B166, B167, b168, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia no ke kuʻi ʻana i ka hao nickel-chromium a me ke kila kila a me ka hoʻoheheʻe ʻana i luna. - nā papa kūʻokoʻa ma ke kila.
ʻO ka hui kemika o ka weld metala(%):
C | Mn | Fe | Si | Ni | Cr |
≤0.05 | ≤5.0 | 7.0 ~ 12.0 | ≤0.8 | ≥50.0 | 28.0 ~ 31.5 |
Cu | Mo | Nb | S | P | 'ē aʻe |
≤0.5 | ≤0.5 | 1.0 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.5 |
Nā waiwai mīkini o ka weld metala:
Mea ho'āʻo | Ka ikaika tensile Mpa | Hua ikaika Mpa | ʻO ka lōʻihi % |
Hōʻoiaʻiʻo | ≥550 | ≥360 | ≥27 |
Manaʻo ʻia i kēia manawa:
Anawaena lāʻau (mm) | 2.5 | 3.2 | 4.0 |
Ke au wiliwili (A) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 |
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.
