Electrode Yekushongedza Simbi Yekupisa Yakaderera
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Tsananguro: W107 ielectrode yesimbi inodziya zvishoma ine hydrogen sodium coating yakaderera.Shandisa DCEP (direct current electrode positive) uye unogona kusveta munzvimbo dzese. Simbi yakachengetwa ichiri yakasimba pakusimba pa -100°C.
Kushandiswa: Kunoshandiswa pakusondera simbi ine tembiricha yakaderera senge 3.5Ni.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Hunhu hwesimbi ye weld:
|
Chinhu chekuyedza |
Simba rekusimba Mpa |
Simba rekupa Mpa | Kureba% | Kukosha kwemhedzisiro (J) -100℃ |
|
Yakavimbiswa | ≥490 | ≥390 | ≥22 | ≥27 |
Kupararira kwehydrogen musimbi yakachengetwa: ≤4.0mL/100g (nzira yeglycerin) kana ≤7.0mL/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 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
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.
