Do I need a welder or can I use rivets?

You can use rivets or a combination of welds and rivets.
Full Answer
You can use rivets or a combination of welds and rivets. Welding provides the strongest, most permanent bond, but rivets are acceptable for non-structural sections or if you lack welding tools. Seal any riveted seams against moisture.
