How do you weld cast iron?
Frequently Asked QuestionsCast iron is a term applied to a wide range of iron-carbon alloys with more than around 1.6% carbon. Cast irons cancover a range of chemical compositions and metallurgical structures which give different mechanical and physicalproperties. The weldability of the different types of cast iron can vary considerably and this requires the use ofdifferent filler metals, welding processes and techniques. Before attempting any weld or repair of cast iron, it isnecessary to determine its type and, preferably, its chemical composition and condition together with the applicationfor which it was designed. Once these factors have been established, it is usually possible to determine whether ornot a weld or repair is feasible together with the optimum process and technique.
