Simbi Inodziya ZvishomaKushongedzaElectrode
W707Ni
GB/T E5515-C1
Tsananguro: W707Ni ielectrode yesimbi ine tembiricha yakaderera ine Ni mu hydrogen sodium coating ine hydrogen shoma. Shandisa DCEP (direct current electrode positive) uye inogona kusungirirwa munzvimbo dzese. Simbi yakachengetwa ichiri yakasimba pa -70°C.
Kushandiswa: Kunoshandiswa pakusondera simbi ine tembiricha yakaderera senge 2.5Ni.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % | Kukosha kwemhedzisiro (J) -70℃ |
| Yakavimbiswa | ≥540 | ≥440 | ≥17 | ≥27 |
Kupararira kwehydrogen musimbi yakachengetwa: ≤6.0mL/100g (nzira yeglycerin) kana ≤10mL/100g (nzira yemercury kana gas chromatography)
Kuongororwa kweX-ray: Giredhi I
Inokurudzirwa yemagetsi:
| (mm) Dhayamita yetsvimbo | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Cherechedza:
- Electrode inofanira kubikwa kweawa imwe pa350℃ isati yashandiswa pakunamira;
- Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira;
- Edza kushandisa simba diki pakusanganisa simbi, kusanganisa simbi dzakawanda uye kusanganisa simbi dzakawanda.
