Haʻahaʻa Welding Steel Welding Electrode
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Hōʻike: W107 he haʻahaʻa haʻahaʻa haʻahaʻa electrode me ka haʻahaʻa-hydrogen sodium coating.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 -100°C.
Hoʻohana: Hoʻohana ʻia no ka wili ʻana i ke kila wela haʻahaʻa e like me 3.5Ni.
ʻO ka hui kemika o ka weld metala(%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Nā waiwai mīkini o ka weld metala:
|
Mea ho'āʻo |
Ka ikaika tensile Mpa |
Hua ikaika Mpa | Elongation% | Waiwai hopena (J) -100 ℃ |
|
Hōʻoiaʻiʻo | ≥490 | ≥390 | ≥22 | ≥27 |
ʻO ka maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤4.0mL/100g (glycerin method) a i ʻole ≤7.0mL/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 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
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.
