It is possible to weld cast iron, although it can be problematic due to the high carbon content. This carbon content is often around 24%, which is about ten times that of most steels. The welding process causes this carbon to migrate into the weld metal and/or the heat affected zone, leading to elevated brittleness/hardness.
Hardfacing, also known as hard surfacing, is the application of buildup or wearresistant weld metals to a part's surface by means of welding or joining. Most worn parts don't fail from a single mode of wear, such as impact, but from a combination of modes, such as abrasion and impact. For example, vertical mill grinding rollers are usually ...
