How to Weld Dirty Cast Iron Parts

Brandon at Zeigler’s Welding, in Olympia, WA, uses Muggy Weld 72 electrode to weld a dirty, heat-affected cast iron manifold.

72 is recommended for non-machinable welds on exhaust manifolds, furnace grates, cast iron stoves, machine bases etc., as it has a high penetration, can anchor deep into the subsurface of dirty cast iron, and seals in porosity generating contaminates.
