Haʻahaʻa Mahana kilawiliwiliElectrode
W707Ni
GB/T E5515-C1
Hōʻike: W707Ni he haʻahaʻa haʻahaʻa haʻahaʻa kila electrode i loaʻa Ni i loko o ka haʻahaʻa-hydrogen sodium uhi.E hoʻohana i ka DCEP (direct current electrode positive) a hiki ke wili ʻia ma nā kūlana āpau.Loaʻa i ka metala i waiho ʻia ka paʻakikī maikaʻi ma -70°C.
Hoʻohana: Hoʻohana ʻia no ka wili ʻana i ke kila wela haʻahaʻa e like me 2.5Ni.
ʻO ka hui kemika o ka weld metala(%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Nā waiwai mīkini o ka weld metala:
| Mea ho'āʻo | Ka ikaika tensile Mpa | Hua ikaika Mpa | ʻO ka lōʻihi % | Waiwai hopena (J) -70 ℃ |
| Hōʻoiaʻiʻo | ≥540 | ≥440 | ≥17 | ≥27 |
ʻO ka maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤6.0mL/100g (ʻano glycerin) a i ʻole ≤10mL/100g (mercury a i ʻole gas chromatography method)
X-ray inspection: I ka helu
Manaʻo ʻia i kēia manawa:
| （mm） Anawaena lāʻau | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| （A） Ke au wiliwili | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Hoʻolaha:
- Pono e kālua ʻia ka electrode no 1 hola ma 350 ℃ ma mua o ka hana wili;
- He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka aila unahi, ka wai, a me nā haumia ma nā ʻāpana wili ma mua o ka wili ʻana;
- E ho'āʻo e hoʻohana i ka ikehu laina liʻiliʻi i ka wā e wiliwili ai, multi-layer a me multi-pass welding.
