Welding Cast Iron With Low Hydrogen Rods. It can only be used for general wood welding. Low hydrogen welding rod can be selected by matching the strength properties and composition of the base metal.
Excellent welding characteristics in all positions except vertically downward. The low hydrogen electrodes have high deposition rates according to Fabricating Metalworking magazine. Low hydrogen welding rod is the generic name used to refer to electrodes or filler metal that is used to join two other base metals when performing shielded metal arc welding.
Choosing electrodes for welding cast iron typically comes down to three things.
CAUSTIC SODA - Pearls - Flakes 4. Using welding consumables like the MG-289 Cast Iron Welding Alloy rods that are designed for contaminated cast iron is the best way to ensure the weld is sufficient. CAUSTIC SODA - Pearls - Flakes 4. Low Hydrogen 7018 3.
