FAQS on what to use to weld cast iron

Q: What is the best method to weld cast iron?

A: Use a nickel-based welding rod (e.g., Ni-CI or Ni-Fe) for stick welding. Preheat the cast iron to 500-1200°F to reduce cracking and cool it slowly post-welding for durability.

Q: Can I weld a backhoe hydraulic pump made of cast iron?

A: Yes, but clean the surface thoroughly and use a low-heat technique like TIG welding with nickel filler. Avoid rapid cooling to prevent structural weaknesses.

Q: What is the price of cast iron per pound?

A: Cast iron typically costs $0.20-$0.50 per pound for scrap, while new material ranges from $1.50-$3.00 per pound, depending on grade and supplier.

Q: Does engine water pump repair require cast iron welding?

A: If the pump housing is cracked, nickel-based welding rods and preheating are essential. Ensure proper post-weld annealing to avoid future leaks.

Q: How costly is cast iron welding compared to replacement?

A: Welding costs $100-$300 for labor and materials, while replacements range from $200-$800. Welding is economical if damage is localized and structural integrity remains.
