ʻElekoda Kuʻihao Kila Kinoea
A302
GB/T E309-16
ʻAWS A5.4 E309-16
Wehewehe: ʻO A302 kahi electrode kila kila Cr23Ni13 me ka uhi titanium-calcium. Hiki ke hoʻohana ʻia no AC a me DC me ka hana hana maikaʻi loa. Loaʻa i ka metala i waiho ʻia ke kūpaʻa maikaʻi loa i ka haki a me ke kūpaʻa oxidation.
Noi: Hoʻohana ʻia no ka hoʻoheheʻe ʻana i ke ʻano like o ke kila kila, ka uhi kila kila, ke kila ʻano kūikawā (ʻo Cr19Ni9 like me ke kila kalapona haʻahaʻa), ke kila chromium kiʻekiʻe, ke kila manganese kiʻekiʻe, a pēlā aku.
Ka hoʻohuihui kemika o ka metala i hoʻoheheʻe ʻia (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.08 | 0.5 ~ 2.5 | ≤0.90 | 18.0 ~ 21.0 | 12.0 ~ 14.0 | 2.0 ~ 4.0 | ≤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） | 2.5 | 3.2 | 4.0 | 5.0 |
| Au Kuʻihao （A） | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Hoʻolaha:
1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma 150 ℃ ma mua o ka hana kuʻihao;
2. No ka mea, he papau ka hohonu o ke komo ʻana i ka wā o ka wiliwili AC, pono e hoʻohana ʻia ka mana DC i ka hiki ke komo hohonu. a ʻaʻole pono e nui loa ke au e pale aku ai i ka ʻulaʻula o ke koʻokoʻo wiliwili.
Ua hoʻokumu ʻia ʻo Wenzhou Tianyu Electronic Co., Ltd. i ka makahiki 2000. Ua hana mākou i ka hana ʻana i nā electrodes wili, nā koʻokoʻo wili, a me nā mea hoʻopau wili no nā makahiki he 20 a ʻoi.
ʻO kā mākou huahana nui e komo pū me nā electrodes wili kila kila, nā electrodes wili kila kalapona, nā electrodes wili hao haʻahaʻa, nā electrodes wili ʻili, nā electrodes wili nickel & cobalt alloy, nā uea wili kila māmā & haʻahaʻa alloy, nā uea wili kila kila, nā uea wili flux cored gas-shielded, nā uea wili alumini, ka wili arc submerged. nā uea, nā uea wili nickel & cobalt alloy, 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.
