Cast iron cracks. It can often be mended.
Careful welding and brazing repair of cracked and broken cast iron: engine and machinery housings, stoves, gates, ornamental pieces, and equipment parts.
- Process: Preheat, nickel filler or brazing
- Technique: Short peened passes
- Cooling: Slow and controlled
What it is, and why it matters.
Cast iron is brittle and sensitive to heat, which is why it cracks when it is welded the wrong way. Repairing it takes preheat, slow cooling, the right nickel-based filler or brazing method and short, peened passes that manage stress.
We assess whether a crack is repairable, stop-drill and prepare it and tell you honestly about the risk. Some parts are worth saving, such as antique ironwork and expensive housings, and some are better replaced. We will help you decide.

Cast Iron Repair: common questions
Can cast iron really be welded?
Yes, in many cases, but it takes preheat, slow cooling and the right filler. Success depends on the part and the crack, and we tell you the odds before we start.
Is brazing better than welding for cast iron?
Sometimes. Brazing uses less heat and can suit thin or delicate pieces, while nickel welding can be stronger on thicker castings. We choose per job.
