Nickel and Nickel Alloy Welding Electrode
Ni327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
ʻO ka wehewehe: ʻO Ni327 -6 kahi electrode nickel-based me ka haʻahaʻa-hydrogen sodium coating.E hoʻohana i ka DCEP (direct current electrodemaikaʻi).ʻO ka metala i waiho ʻia he plasticity maikaʻi loa, ka paʻakikī a me ke kūʻē ʻana.Loaʻa i ka metala i hoʻopaʻa ʻia he laina hoʻonui like me ke kila, a loaʻa ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion ikaika ma ka lumi wela a me ka wela kiʻekiʻe.
Hoʻohana: Hoʻohana ʻia ia no ka hoʻopaʻa ʻana i ke kila Ni9%, a hiki ke hoʻohana ʻia no ka hoʻopili ʻana i nā kila like ʻole a me nā mea paʻakikī i ka weld.
ʻO ka hui kemika o ka weld metala(%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | 'ē aʻe |
|
| 0.5 ~ 2.0 | 1.0 ~ 2.0 | 12.0 ~ 17.0 | ≤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 | ≥620 | ≥350 | ≥32 |
Manaʻo ʻia i kēia manawa:
| Anawaena lāʻau （mm） | 2.5 | 3.2 | 4.0 |
| Ke au wiliwili （A） | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Hoʻolaha:
1. Pono e kālua ʻia ka electrode no 1 hola ma kahi o 300 ℃ ma mua o ka hana wili.E ho'āʻo e hoʻohana i kahi pōkā pōkole e wili ai；
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.
3. E ho'āʻo e hoʻohana i ka ikehu laina liʻiliʻi i ka wā e wiliwili ai, multi-layer a me multi-pass welding.
