W707Ni
GB/T E5515-C1
Tsanangudzo: W707Ni isimbi yakadzika-tembiricha electrode ine Ni mune yakaderera-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka) uye inogona kusungirirwa munzvimbo dzese.Simbi yakaiswa ichiri iine kunaka kwekusimba pa -70°C.
Chikumbiro: Inoshandiswa pakushongedza yakaderera tembiricha simbi senge 2.5Ni.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % | Impact value (J) -70 ℃ |
| Guaranteed | ≥540 | ≥440 | ≥17 | ≥27 |
Diffusion hydrogen yemukati mesimbi yakaiswa: ≤6.0mL/100g (glycerin nzira) kana ≤10mL/100g (mercury kana gasi chromatography nzira)
X-ray kuongorora: Ini giredhi
Yazvino inokurudzirwa:
| (mm) Tsvimbo dhayamita | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Cherechedza:
- Iyo electrode inofanira kubikwa kweawa imwe pa350 ℃ isati yaitwa welding;
- Zvinokosha kuchenesa ngura, chikero chemafuta, mvura, uye tsvina pazvikamu zvewelding tisati taputirwa;
- Edza kushandisa simba remutsara mudiki paunenge uchitsvaira, multi-layer uye multi-pass welding.
