Low Alloy Karfe Welding Electrode
Saukewa: J707RH
GB/T E7015-G
Saukewa: AWS E10015-G
Bayani: J707RH shine babban tauri ultra-low hydrogen electrode tare da ƙarancin murfin sodium na hydrogen.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye) kuma ana iya haɗa shi a kowane matsayi. Ayyukan aikin walda yana da kyau.Lankwasawa mai sanyi, juriya mai tsauri da juriya na fashewar haɗin gwiwar welded suna da kyau.Ƙarfin da aka ajiye yana da babban filastik da tauri.
Aikace-aikace: Ana amfani da waldi na hull Tsarin, kuma shi ne ma dace da waldi na muhimmanci Tsarin Rp0.2≥590MPa high-ƙarfi karfe.
Abubuwan sinadaran na weld karfe(%):
| C | Mn | Cr | Si | Ni | Mo | S | P | S + P |
| ≤0.10 | 1.20 ~ 1.60 | 0.08 ~ 0.20 | 0.30 ~ 0.60 | 1.40 ~ 2.00 | 0.25 ~ 0.50 | ≤0.020 | ≤0.020 | ≤0.035 |
Abubuwan kayan aikin walda:
| Gwaji abu | Ƙarfin ƙarfi Mpa | Ƙarfin bayarwa Mpa | Tsawaitawa % | Ƙimar tasiri (J) -50 ℃ |
| Garanti | ≥ 690 | ≥590 | ≥15 | ≥34 |
Yadawa hydrogen abun ciki na ajiyar karfe: ≤4.1mL / 100g (Mercury ko gas chromatography hanya)
Duban X-ray: I grade
Shawarwari na yanzu:
| (mm) da Diamita na sanda | 4.0 | 5.0 |
| (A) Welding Current | 160 ~ 180 | 180 ~ 220 |
Sanarwa:
1. Dole ne a gasa wutar lantarki don 2 hour a 400 ℃ kafin aikin walda;
2. Yana da mahimmanci don tsaftace tsatsa, sikelin mai, ruwa, da ƙazanta akan sassan walda kafin walda;
3. Yi amfani da gajeriyar aikin baka lokacin walda.kunkuntar waƙar walda ta dace.
