Yakaderera Tembiricha Simbi Welding Electrode
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Tsanangudzo: W107 isimbi yakadzika-tembiricha electrode ine yakaderera-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka) uye inogona kusungirirwa munzvimbo dzese.Simbi yakaiswa ichiri iine kunaka kwesimba kusimba pa -100°C.
Chikumbiro: Inoshandiswa pakushongedza yakaderera tembiricha simbi senge 3.5Ni.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Mechanical zvimiro zve weld simbi:
|
Test chinhu |
Kusimba simba Mpa |
Goho simba Mpa | Elongation% | Impact value (J) -100℃ |
|
Guaranteed | ≥490 | ≥390 | ≥22 | ≥27 |
Diffusion hydrogen yemukati mesimbi yakaiswa: ≤4.0mL/100g (glycerin nzira) kana ≤7.0mL/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 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
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.
