The frequently asked question “Can cast iron be welded?” is not unjustified.
This is because, depending on the type, cast iron is considered in the technical literature to be either only conditionally weldable (carbon is present in globular form) or not weldable at all (carbon is present in lamellar form).
However, at TM Lasertechnik we have often been able to prove the opposite. There are conditions under which cast iron can also be welded in lamellar form.
