If you want to consider the strength requirements after welding, it is recommended not to weld. If you want to weld together without too much force, it is possible. You can weld with stainless steel electrode or cast iron electrode.
1. Before welding, proper surface cleaning shall be done, and the welded joint shall be obliquely cut into a U-shaped groove.
2, stop crack holes at both ends of the crack to prevent crack expansion during welding.
3. When the repair angle is not good, U-shaped or V-shaped groove formed by cold slotting of WE100 electrode can be selected.
4, as small as possible for welding current, medium arc length, slightly inclined to the welding direction.
5. It is recommended to use short and thin welding beads and narrow transverse swing welding torches for welding passes. Before stopping arc welding, fill the weld joint, usually without heat treatment, and allow the parts to cool slowly.
If you want to consider the strength requirements after welding, it is recommended not to weld. If you want to weld together without too much force, it is possible. You can weld with a stainless steel electrode or a cast iron electrode.
But the rust on the surface needs to be polished. Copper welding wire for pig iron and steel plate belongs to brazing and has no strength at all, and because the high brazing temperature will also lead to the risk of cracking of pig iron. Generally, special cast iron welding rods for dissimilar welding of pig iron and steel plate, such as WEWELDING777 cast iron welding rods for flange of carbon steel or elbow welding of ball-milled cast iron and carbon steel in some projects, can be welded by cold welding process.
