Electrode Yekushongedza Simbi Yekupisa Yakaderera
W607
GB/T E5015-G
AWS A5.5 E7015-G
Tsananguro: W607 ielectrode yesimbi inodziya zvishoma ine hydrogen sodium coating yakaderera. Shandisa DCEP (direct current electrode positive) uye inogona kusungirirwa munzvimbo dzese. Simbi yakachengetwa ine simba rakanaka pa -60°C.
Kushandiswa: Kunoshandiswa pakushongedza simbi ine tembiricha yakaderera senge 09MnD.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤0.020 | ≤0.025 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % | Kukosha kwemhedzisiro (J) -60℃ |
| Yakavimbiswa | ≥490 | ≥390 | ≥22 | ≥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 | 100 ~ 120 | 140 ~ 170 | 170 ~ 200 |
Cherechedza:
1. Electrode inofanira kubikwa kweawa imwe pa350℃ isati yashandiswa pakunamira;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira;
3. Chikamu chakasungirirwa chinogona kupikiswa pakupisa kunenge 150°C chisati chasungirirwa kudzivirira kutsemuka.
