Molybdenum a me Chromium Molybdenum Heat Resistant SteelwiliwiliElectrode
R107
GB/T E5015-A1
AWS A5.5 E7015-A1
ʻO ka wehewehe: R107 he pearlitic heat-resistant steel electrode me ka haʻahaʻa-hydrogen sodium coating i loaʻa ka 0.5% Mo. E hoʻohana i ka DCEP (direct current electrode positive) a hiki ke welded i nā kūlana āpau. .
Hoʻohana: Hoʻohana ʻia ia no ka hoʻopili ʻana i nā paipu paila me ka mahana hana ma lalo o 510 ° C (e like me 15Mo, a me nā mea ʻē aʻe), a hiki ke hoʻohana ʻia no ke kuʻi ʻana i ke kila ikaika kiʻekiʻe.
ʻO ka hui kemika o ka weld metala(%):

Nā waiwai mīkini o ka weld metala:
| Mea ho'āʻo | Ka ikaika tensile Mpa | Hua ikaika Mpa | ʻO ka lōʻihi % | Waiwai hopena (J) Ma'amau Temp. |
| Hōʻoiaʻiʻo | ≥490 | ≥390 | ≥22 | ≥47 |
Maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤6.0mL/100g (ʻano glycerin)
X-ray inspection: I ka helu
Manaʻo ʻia i kēia manawa:
| Anawaena lāʻau （mm） | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |

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 ʻaila unahi, ka wai, a me nā haumia ma nā ʻāpana wili ma mua o ka wili ʻana.
