Nickel and Nickel Alloy Welding Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
ʻO ka wehewehe: Ni202 he Ni70Cu30 Monel alloy electrode me ka titanium calcium coating. Hiki ke hoʻohana ʻia no ka AC a me DC.ʻO ka metala i waiho ʻia he kūpaʻa maikaʻi ma muli o ka ʻike kūpono o ka manganese a me ka niobium.Loaʻa iā ia ka hana hoʻoheheʻe maikaʻi me ka hoʻopau ʻana i ka arc paʻa, ka liʻiliʻi o ka spatter, maʻalahi ka wehe ʻana i ka slag, a me ka weld nani.
Hoʻohana: Hoʻohana ʻia ia no ka hoʻopili ʻana i ka nickel-copper alloy a me ke kila like ʻole, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻololi.
ʻO ka hui kemika o ka weld metala(%):
C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥62.0 | ≤0.015 | ≤0.020 |
Nā waiwai mīkini o ka weld metala:
Mea ho'āʻo | Ka ikaika tensile Mpa | Hua ikaika Mpa | ʻO ka lōʻihi % |
Hōʻoiaʻiʻo | ≥480 | ≥200 | ≥27 |
Manaʻo ʻia i kēia manawa:
Anawaena lāʻau (mm) | 2.5 | 3.2 | 4.0 |
Ke au wiliwili (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Hoʻolaha:
1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma kahi o 250 ℃ 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.
