Low Zazzabi Karfe Welding Electrode
W607
GB/T E5015-G
AWS A5.5 E7015-G
Description: W607 ne a low-zazzabi karfe lantarki da low-hydrogen sodium shafi.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye) kuma yana iya waldawa a duk wurare.Ƙarfin da aka ajiye yana da tasiri mai kyau a -60 ° C.
Aikace-aikace: Ana amfani da shi don walda ƙananan zafin jiki kamar 09MnD.
Abubuwan sinadaran na weld karfe(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤0.020 | ≤0.025 |
Abubuwan kayan aikin walda:
| Gwaji abu | Ƙarfin ƙarfi Mpa | Ƙarfin bayarwa Mpa | Tsawaitawa % | Ƙimar tasiri (J) -60 ℃ |
| Garanti | ≥490 | ≥390 | ≥22 | ≥27 |
Yadawa hydrogen abun ciki na ajiya karfe: ≤6.0ml/100g (glycerin hanya) ko ≤10mL/100g (mercury ko gas chromatography hanya)
Duban X-ray: I grade
Shawarwari na yanzu:
| (mm) da Diamita na sanda | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 40 ~ 70 | 60 ~ 90 | 100 ~ 120 | 140 ~ 170 | 170 ~ 200 |
Sanarwa:
1. Dole ne a gasa wutar lantarki don 1 hour a 350 ℃ kafin aikin walda;
2. Yana da mahimmanci don tsaftace tsatsa, sikelin mai, ruwa, da ƙazanta akan sassan walda kafin walda;
3. Za a iya preheated ɓangaren da aka yi masa walda a kimanin 150 ° C kafin a yi walda don hana tsagewa.
