Electrode Yesimbi Yekushongedza Yesimbi Yakaderera
J556Fe
GB/T E5518-G
AWS E8018-G
Tsananguro: J556fe ielectrode yesimbi ine upfu hwesimbi uye hydrogen yakaderera. AC neDC zvinogona kushandiswa, uye zvinogona kusungirirwa munzvimbo dzese.
Mashandisirwo: Inoshandiswa pakusanganisa simbi yekabhoni iri pakati nepakati uye simbi ine alloy yakaderera senge Q390.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | S | P |
| ≤0.12 | ≥1.00 | ≤0.80 | ≤0.035 | ≤0.035 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % | Kukosha kwemhedzisiro (J) -40℃ |
| Yakavimbiswa | ≥540 | ≥440 | ≥17 | ≥27 |
Kupararira kwehydrogen musimbi yakachengetwa: ≤10.0mL/100g (nzira ye mercury kana gas chromatography)
Kuongororwa kweX-ray: Giredhi I
Inokurudzirwa yemagetsi:
| (mm) Dhayamita yetsvimbo | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 70 ~ 110 | 100 ~ 140 | 140 ~ 170 | 190 ~ 240 |
Cherechedza:
1. Electrode inofanira kubikwa kweawa imwe pa350℃ isati yashandiswa pakunamira;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira;
3. Shandisa nzira pfupi yekupinza simbi pakusanganisa simbi. Nzira yakamanikana yekusanganisa simbi ndiyo yakakodzera.
