Electrode Yesimbi Yekushongedza Yesimbi Yakaderera
J606
GB/T E6016-D1
AWS E9016-D1
Tsananguro: J606 ielectrode yesimbi ine simba rakawanda ine hydrogen potassium coating shoma. Inogona kushandiswa pakushongedza nzvimbo dzese neAC neDC. Kugadzikana kwekushanda kweAC welding kwakaderera pane kweDC welding.
Mashandisirwo: Inoshandiswa pakushongedza simbi yepakati nepakati ine kabhoni uye simbi ine simba rakaderera, senge Q420, nezvimwewo.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | Mo | S | P |
| ≤0.12 | 1.25 ~ 1.75 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.035 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % | Kukosha kwemhedzisiro (J) -30℃ |
| Yakavimbiswa | ≥590 | ≥490 | ≥15 | ≥27 |
| Yakaedzwa | 620 ~ 680 | ≥500 | 20 ~ 28 | ≥27 |
Kupararira kwehydrogen musimbi yakachengetwa: ≤4.0mL/100g (nzira yeglycerin)
Kuongororwa kweX-ray: Giredhi I
Inokurudzirwa yemagetsi:
| (mm) Dhayamita yetsvimbo | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 | 5.8 |
| (A) Welding Current | 40 ~ 70 | 70 ~ 90 | 90 ~ 120 | 140 ~ 180 | 180 ~ 220 | 210 ~ 260 |
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 arc operation pfupi pakusanganisa. Nzira yakamanikana yekusanganisa ndiyo yakakodzera;
4. Kana chikamu cheweld chakora, chinofanira kupiswa kusvika pamusoro pe150°C uye kutonhodzwa zvishoma nezvishoma mushure mekuwelda.
