It isn't cast iron - it is CRS and steel tubing

So if it is carbon steel then try cleaning all the dirt and grit off. We used to use a flex sanding disk on our hand held grinders to get pass the surface near the weld area or seam. In some cases we would use a hard disk and cut weld grooves for deeper penetration. I like stick welding when I was in my apprenticeship. We were taught to use several different types of welders but once outside the training never touched one again.

Good luck on getting your project finished.
