- For your next practice, try
- working with different thick-
- nesses of steel. Working with
- pieces both thicker and thinner,
- you will notice that you have to
- change your techniques somewhat.
- Experiment with torch angle,
- flame size and speed of movement
- from right to left. How thin
- gauge steel can you weld? See if
- you can weld 1/4" thick steel
- without difficulty.~

- If you need to weld anything
- thicker than 1/4" extra precaut-
- ions will be necessary. The
- sparks and slag will be bigger
- and travel farther. The heat
- generated will be more dangerous

- Try mitering and welding two
- pieces of round tubing. You can
- use old American-made bicycle
- frame tubing again.
- Miter one of the tubes to
- fit against the other with a
- large rat-tail file. Try to get
- a fit accurate within 1/8" all
- the way around. Weld them toget-
- her as indicated, let them cool,
- then smash them apart with a
- hammer.
