This is a question on types of steel.

I have the welding cart I made with mild steel. I was thinking of welding some large ubolts on the side to hold cables.

The bolts I have are normal shiny metal bolts (not stainless, not galvinized). Can I weld it to mild steel with MIG using 25% CO2 without anything special?

I could try it and see what happens - but I really appreciate the responses when I ask a question in the forums. I always learn more than I would expect.

Thanks in advance.
