Molybdenum neChromium Molybdenum Molybdenum Electrode Yekushongedza Simbi Inodzivirira Kupisa
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Tsananguro: R407 ielectrode yesimbi inodzivirira kupisa ine hydrogen sodium coating shoma ine 2.5% Cr - 1% Mo. Shandisa DCEP (direct current electrode positive) uye inogona kusungirirwa munzvimbo dzese. Kusungirirwa kunofanirwa kupiswa kusvika 200 ~ 300°C usati wabatanidza.
Mashandisirwo: Inoshandiswa pakunamira mapaipi anodziya zvakanyanya uye ane kumanikidzwa kwakanyanya ane tembiricha iri pasi pe550°C, michina yemakemikari yakagadzirwa, michina yekupwanya peturu, nezvimwewo.
Kuumbwa kwemakemikari esimbi ye weld (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
Hunhu hwesimbi ye weld:
| Chinhu chekuyedza | Simba rekusimba Mpa | Simba rekupa Mpa | Kureba % | Kukosha kwemhedzisiro (J) Kupisa Kwakajairika. |
| Yakavimbiswa | ≥590 | ≥490 | ≥15 | ≥47 |
| Yakaedzwa | 600 ~ 680 | ≥500 | 18 ~ 21 |
Kupararira kwehydrogen musimbi yakachengetwa: ≤4.0mL/100g (nzira yeglycerin)
Kuongororwa kweX-ray: Giredhi I
Inokurudzirwa yemagetsi:
| Dhayamita yetsvimbo (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Cherechedza:
1. Electrode inofanira kubikwa kweawa imwe pa350℃ isati yashandiswa pakunamira;
2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira.
