How To Weld Cast Iron With Tig. View Cast Iron Stick Electrodes. MIG welding cast iron Although cast iron can be welded with the MIG process and specialised flux-cored electrode wires the resulting welded joint wont be as strong as with MMA arc welding.
China has a high carbon content which may cause it to become brittle or harden irregularly both of which may cause unexpected breakage during the welding process. Aluminum bronze tig welding rods are much cheaper than nickel rods. A good tip for using this rod on welding iron castings is to set the gtaw machine on AC just like you would weld aluminum.
Prepare the electrode by grinding it to a point and inserting it into the collet.
Once a good weld deposit is made the two sides of the crack can be welded together. Youll end up cracking it. MIG welding cast iron Although cast iron can be welded with the MIG process and specialised flux-cored electrode wires the resulting welded joint wont be as strong as with MMA arc welding. Once you try to curtail the extreme heat and quick cooling of the electric welding process then oxy-acetylene is the option.
