Cast iron is difficult, but not impossible, to weld. In the past, cast iron was always difficult to repair: heat the part slowly in an oven, make the weld with a nickel rod, slowly cool the part in an oven--and hope the cast iron would not rickrack (it frequently did). Most welders wouldn't even attempt to weld cast iron due to the temperamental nature of such repairs. Fortunately, times have changed. Muggy Weld offers two solutions for cast iron repair: arc electrodes and gas torch rods.

Welding is a method of fabrication used by joining metals or thermoplastics, with the help of coalescence. In involves the melting of work pieces and addition of a filler material to form a pool of molten material. This weld pool cools to become a strong joint, in order to produce the weld. Remembering this is helpful when welding cast iron: during and after welding, the casting must either be allowed to cool slowly, or should be kept cool enough that the rate of cooling is not important.
