J556F
GB/T E5518-G
AWS E8018-G
Bayani: J556fe shine ƙaramin ƙarfe na ƙarfe na ƙarfe tare da foda baƙin ƙarfe da ƙaramin murfin hydrogen.Dukansu AC da DC ana iya amfani da su, kuma ana iya walda su a kowane matsayi.
Aikace-aikacen: Ana amfani da shi don walƙiya matsakaicin ƙarfe na ƙarfe da ƙananan ƙirar ƙarfe kamar Q390.
Abubuwan sinadaran na weld karfe(%):
| C | Mn | Si | S | P |
| ≤0.12 | ≥1.00 | ≤0.80 | ≤0.035 | ≤0.035 |
Abubuwan kayan aikin walda:
| Gwaji abu | Ƙarfin ƙarfi Mpa | Ƙarfin bayarwa Mpa | Tsawaitawa % | Ƙimar tasiri (J) -40 ℃ |
| Garanti | ≥540 | ≥440 | ≥17 | ≥27 |
Yadawa hydrogen abun ciki na ajiyar karfe: ≤10.0ml/100g (Mercury ko gas chromatography hanya)
Duban X-ray: I grade
Shawarwari na yanzu:
| (mm) da Diamita na sanda | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 70 ~ 110 | 100 ~ 140 | 140 ~ 170 | 190 ~ 240 |
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. Yi amfani da gajeriyar aikin baka lokacin walda.kunkuntar waƙar walda ta dace.
