YD55-J
Description:
YD55-J is a gas-shielded flux-cored wire. Welding arc stability, slag easy. The product crack resistance, multi-layer welding is not easy to crack.
use:
Suitable for high impact, highly abrasive conditions. For single or multi-layer welding all kinds of worn parts surface repair, such as gears, dredging bucket, construction machinery, mining machinery.

Precautions:
1 welding workpiece should be degreasing, rust treatment.
2. Welding, the gas flow is generally 20 ~ 25L / min.
3 flux cored welding, dry elongation should be 15 ~ 25mm.
4 in the welding of large parts should be properly preheated to about 300 ℃.
5. Wire warehouse humidity should be maintained at less than 60%.
6. Non-vacuum packaging wire storage time should not exceed six months, vacuum packaging wire storage time should not exceed one year.
