How can the ductile iron pipe be welded?
If the hole on the ductile iron pipe, you can use special hoop lined flexible rubber ring, rubber ring and pipe wall coating with rubber ring, glue to be fixed.
Welding cast iron is mainly in three aspects: carbon control, stress elimination, structural adjustment. You can choose better welding materials, such as WE777 and other imported welding materials. Crack resistance is very good. In addition, the sewing process can be adopted in the structure to increase the stability of the welding effect. You can learn more about WE777 welding applications.
The nickel electrode cold welding, such as Z408
