ʻElektrode Kuʻi kila Haʻahaʻa Mahana
W107
GB/T E5015-C2L
ʻAWS A5.5 E7015-C2L
Wehewehe: ʻO W107 kahi electrode kila haʻahaʻa me ka uhi sodium haʻahaʻa-hydrogen.E hoʻohana i ka DCEP (direct current electrode positive) a hoʻopaʻa ʻia ka hiki ma nā kūlana āpau. Loaʻa i ka metala i waiho ʻia ka paʻakikī hopena maikaʻi ma -100°C.
Hoʻohana: Hoʻohana ʻia no ka hoʻoheheʻe ʻana i ke kila haʻahaʻa e like me 3.5Ni.
Ka hoʻohuihui kemika o ka metala i hoʻoheheʻe ʻia (%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Nā ʻano mechanical o ka metala i hoʻoheheʻe ʻia:
|
Mea hoʻāʻo |
Ikaika tensile Mpa |
Ikaika hāʻawi Mpa | Hoʻolōʻihi% | Ka waiwai hopena (J) -100 ℃ |
|
Hōʻoiaʻiʻo ʻia | ≥490 | ≥390 | ≥22 | ≥27 |
Ka nui o ka hydrogen diffusion o ka metala i waiho ʻia: ≤4.0mL/100g (ʻano glycerin) a i ʻole ≤7.0mL/100g (ʻano mercury a i ʻole gas chromatography)
Nānā X-ray: papa I
Manaʻo ʻia kēia manawa:
| （mm） Anawaena o ke koʻokoʻo | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| （A） Au Kuʻihao | 40 ~ 70 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
Hoʻolaha:
- Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma 350 ℃ ma mua o ka hana kuʻihao;
- He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka unahi aila, ka wai, a me nā mea haumia ma nā ʻāpana kuʻi ma mua o ka kuʻi ʻana;
- E hoʻāʻo e hoʻohana i ka ikehu laina liʻiliʻi i ka wā e kuʻi ai, ka kuʻi multi-layer a me ka multi-pass.
