Hello yall. I need to weld a Cast iron steel seat bracket onto a mild steel motorcycle frame. What is the best process to weld this? Can it be welded GTAW process? What filler rod will be the most optimal? I talked with a old timer welder he suggested I weld a bead with a stainless rod not sure what grade onto the cast part. Then weld ontop of the stainless ontop the mild steel does this sound like a goood Idea? I am thinking i should SMAW weld it but my uncle wants done in GTAW. Some advice would be great.
