Haʻahaʻa Welding Steel Welding Electrode
W607
GB/T E5015-G
AWS A5.5 E7015-G
Hōʻike: W607 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.ʻO ka metala i hoʻopaʻa ʻia he hopena maikaʻi ka paʻakikī ma -60 ° C.
Hoʻohana: Hoʻohana ʻia no ka wili ʻana i ke kila wela haʻahaʻa e like me 09MnD.
ʻO ka hui kemika o ka weld metala(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤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) -60 ℃ |
| Hōʻoiaʻiʻo | ≥490 | ≥390 | ≥22 | ≥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 | 100 ~ 120 | 140 ~ 170 | 170 ~ 200 |
Hoʻolaha:
1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma 350 ℃ ma mua o ka hana wili;
2. 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;
3. Hiki ke hoʻomehanaʻia ka'āpana welded ma kahi o 150 ° C ma mua o ka wiliʻana e pale i nā māwae.
