Nickel uye Nickel Alloy Welding Electrode
Ni327-6
GB/T ENi6620
AWS A5.11 ENCrMo-6
Tsanangudzo: Ni327 -6 is nickel-based electrode ine low-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrodepositive).Simbi yakaiswa ine yakanakisa plastiki, kuoma uye kutsemuka kuramba.Deposited metal ine linear yekuwedzera coefficient yakafanana neiyo yesimbi, uye ine simba rakawanda uye yakasimba inodzivirira ngura patembiricha yekamuri uye tembiricha yepamusoro.
Chikumbiro: Inoshandiswa pakunama yeNi9% simbi, uye inogona zvakare kushandiswa kugadzira simbi dzakasiyana uye yakaoma-ku-weld alloys.
Kemikari yakagadzirwa nesimbi weld (%):
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 | Zvimwe |
|
0.5 ~ 2.0 | 1.0 ~ 2.0 | 12.0 ~ 17.0 | ≤0.015 | ≤0.020 | ≤0.5 |

Mechanical zvimiro zve weld simbi:
Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % |
Guaranteed | ≥620 | ≥350 | ≥32 |
Yazvino inokurudzirwa:
Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 |
Welding ikozvino (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Cherechedza:
1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 300 ℃ isati yaitwa welding.Edza kushandisa arc pfupi kuti weld;
2. Zvakakosha kuchenesa dzine ngura, oiri, mvura, uye tsvina pazvikamu zvinonamatwa tisati tapisa.
3. Edza kushandisa simba remutsara mudiki paunenge uchitsvaira, multi-layer uye multi-pass welding.
