I mean it welded just like the raw pipe I rerouted around the steering arm, it was for a circle track truck. Kind of surprised it welded as well as it did since it was coated inside.
It was mild steel, it didn't need back purged and I don't know if he ever ran it on the track.
So some one takes a cracked header to a welder to repair then expects the welder to guarentee it will not crack like it did from the factory.
