Nickel and Nickel Alloy Welding Electrode
Ni327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
Whakaahuatanga: Ko te Ni327 -6 he electrode nickel-based me te iti-hydrogen sodium coating.Whakamahia te DCEP (direct current electrodepai).He pai rawa te kirihou, te pakari me te kapiti o te konganuku kua penapena.Ko te konganuku kua penapena he whakarea roha rarangi rite ki tera o te maitai, he kaha te kaha me te kaha o te waikura i te pāmahana rūma me te pāmahana teitei.
Taupānga: Kei te whakamahia te reira mo te fehokotaki'anga o Ni9% maitai, a ka taea hoki te whakamahi mo te fehokotaki'anga o maitai rerekē me koranu uaua-ki-weld.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Ētahi atu |

Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % |
| Ka whakamanahia | ≥620 | ≥350 | ≥32 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 |
| Waehere naianei （A） | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Panui:
1. Me tunu te electrode mo te 1 haora i te 300 ℃ i mua i te mahi fehokotaki.Ngana ki te whakamahi i te pewa poto ki te wea;
2. He mea nui ki te horoi i te waikura, te hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.
3. Whakamātauria ki te whakamahi i te pūngao raina iti ina fehokotaki'anga, maha-apa me te maha-haere fehokotaki'anga.
