Why does cast iron crack when welded?

Identify the alloy It is less malleable in comparison to steel or wrought iron. The heating and cooling cycles during welding cause expansion and contraction in the metal, inducing tensile stress. Cast irons do not stretch or deform when heated or stressed—instead, they crack—making them extremely difficult to weld.

How do you repair a cast iron pipe joint?

1. Step 1: Clean Away Corrosion. If water or a bad smell comes from an old leaded joint, use a cold chisel and hammer to gently tap the lead back into the joint.
