Metallurgy for Welders

     Lets face it, if you wield a welding torch for a living like I do, you probably don't have a degree in Metallurgical Engineering. People like us rely on experience and destructive testing as a form higher education. I came across this article from The-Fabricator.com that takes a no-nonsense approach to basic metallurgy for welders. Check it out here, Metallurgy for Welders
     Also I've heard good reviews on the book Metallurgy for the non-Metallurgist from Amazon.com.
Its a bit pricey though, it goes for two bills.

Tube Coping Calculator

     Without the right tools, coping tubing can be confusing to layout by hand especially when offsets are involved. I came across this calculator in a dark corner of the internet. I printed out a few of these and they're pretty accurate. You're welcome. Cope tubing manually.
