Kuʻihao kila kilaʻElekoda
A317
GB/T E309Mo-15
ʻAWS A5.4 E309Mo-15
Wehewehe: He electrode kila kila ʻo A317 me ka uhi sodium hydrogen haʻahaʻa. E hoʻohana i ka DCEP (electrode current direct). ʻOi aku ka maikaʻi o kona kūpaʻa i ka pala, ka haki, a me ka oxidation ma mua o A302 no ka mea aia ka molybdenum i loko o ka metala i waiho ʻia.
Noi: Hoʻohana ʻia no ka hoʻoheheʻe ʻana i ke ʻano like o ke kila kila, ka papa kila hui pū ʻia a me ke kila like ʻole i kū i ka corrosion medium sulfuric acid (sulfur ammonia).
Ka hoʻohuihui kemika o ka metala i hoʻoheheʻe ʻia (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.12 | 0.5 ~ 2.5 | ≤0.90 | 22.0 ~ 25.0 | 12.0 ~ 14.0 | 2.0 ~ 3.0 | ≤0.75 | ≤0.030 | ≤0.040 |
Nā ʻano mechanical o ka metala i hoʻoheheʻe ʻia:
| Mea hoʻāʻo | Ikaika tensile Mpa | Hoʻolōʻihi % |
| Hōʻoiaʻiʻo ʻia | ≥550 | ≥25 |
Manaʻo ʻia kēia manawa:
| Anawaena o ke koʻokoʻo （mm） | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Au Kuʻihao （A） | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Hoʻolaha:
Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma kahi o 250 ℃ ma mua o ka hana kuʻihao.
Ua hoʻokumu ʻia ʻo Wenzhou Tianyu Electronic Co., Ltd. i ka makahiki 2000. Ua hana mākou i ka hana ʻana oʻeleka uila hoʻoheheʻes, nā koʻokoʻo wili, a menā mea hoʻopau kuʻihaono nā makahiki he 20 a ʻoi.
ʻO kā mākou huahana nui e komo pū me ke kila kilaʻeleka uila hoʻoheheʻes, nā electrodes wili kila kalapona, nā electrodes wili hao haʻahaʻa, nā electrodes wili ʻili, nā electrodes wili hao nickel & cobalt, nā uea wili kila akahai & haʻahaʻa, nā uea wili kila kila ʻole, nā uea wili flux cored gas-shielded, nā uea wili alumini, ka wili arc submerged. nā uea, nā uea wili hao nickel & cobalt, nā uea wili keleawe, nā uea wili TIG & MIG, nā electrodes tungsten, nā electrodes gouging kalapona, a me nā mea pono wili a me nā mea hoʻopau ʻē aʻe.
