There is a new encyclopedia (or "wiki") of welding and gases terms online sponsored by the Gases and Welding Distributors Association (GAWDA). It's called GAWDAwiki. [url]www.gawdawiki.org/gwiki/index.php/Main_Page[/url]
The wiki is interactive, which means you can use it as a reference, add new terms and definitions, or add more information to existing terms. Please take a look at it and see what you think. It's a great tool for beginners and pros!
