Hereof, can I weld to cast iron?
Cast iron is difficult, but not impossible, to weld. In most cases, welding on cast iron involves repairs to castings, not joining casting to other members. The repairs may be made in the foundry where the castings are produced, or may be made to repair casting defects that are discovered after the part is machined.
Additionally, can you weld cast iron with mild steel MIG wire? Cast iron can be welded perfectly well using a stick welder and nickel rods, or with pre-heating by a gas welder using cast iron rod. But what if you fancy doing it with a MIG welder? It can be done, and without too much difficulty, although the resulting join won't be as strong as the more accepted methods.
Accordingly, what kind of welding rod do you use on cast iron?
There are two common types of Cast iron Welding Rod, Ferro-Nickel and Pure Nickel. Ferro-Nickel are typically 53% Steel and 47% Nickel. Ferro-Nickel Rods are cheaper than pure Nickel and are ideal for welding Cast Iron to Steel. Pure Nickel will produce a softer, more malleable weld deposit.
Can I weld cast iron with a MIG welder?
MIG Welding Cast Iron While any professional wouldn't recommend MIG over other forms, welding cast iron is very much possible with a MIG welder. The best choice in MIG wire would be specialty nickel wire, but this is the most expensive option, stainless steel MIG wire can also be used.
