I was thinking of using these interlocking tube connectors to attach my engine cage to the frameThe connectors are chromoly and the cage is mild steel, is it ok to just mig that like normal?
Reply:Do you know what kind of chromoly?depending oon the carbon content, preheating might be necessary.Mig with "normal" wire will most likely do fine (depending on the grade of chromoly).
