  • Guidelines for Welding Cast Iron

    A few facts about cast iron help in understanding the welding challenges. Cast iron typically has a carbon content of 2% 4%, roughly 10 times as much as most steels. The high carbon content causes the carbon to form flakes of graphite. This graphite gives gray cast iron its characteristic appearance when fractured.
