How to Weld Cast Iron | Metal Casting Blog
2020-5-22 · The welding rod should be melted in the molten weld pool, rather than directly by the flame, to minimize temperature gradients. Braze welding. Braze welding is a common method for joining cast iron parts due to the minimal impact on the base metal itself. A welding rod provides the filler that adheres to the cast iron surface.
Tips for Choosing the Right Contact Tip | Bernard
However, when wire is fed from a drum (e.g. those 500 pounds and larger) and/or when using solid wire, an undersized contact tip may improve welding performance. Because wire from a drum tends to have less cast, it feeds through the contact tip with less or no contact — having a smaller bore exerts more pressure on the wire, creating greater
