Capping Metal Pipe
On most welding projects involving round pipe, rectangle or square tubing, its almost inevitable to have an open end some where. This is not recommended for a variety of reasons. General appearance and appeal are just one.
- Moisture in the environment will eventually begin to rust the metal from the inside out.
- Open ends on outdoor projects will not only attract insects, they will allow a nice place for them to live and thrive.
- Its impossible to paint the inside of metal pipe and tubing.
- Overall appearance is diminished.
- Capped ends complete any metalworking project.
Step 1. Cut the Caps
No matter what size pipe or tubing, the first step is easy. Cut the caps, or parts you plan to use to weld over the open ends. For these 2″ metal rockers I use 18 gauge sheet metal cut into small octagons. The caps should be cut just enough to cover the openings, but not hang over the edges.
