Luckily, this handy little volume caught my eye. "How to Weld 29 Metals" is, well, just that. I learned that low-carbon steel is pretty much a welder's dream, whereas high carbon steel makes arc welders cry. Well, not really, but it does require a little more cajoling (heat treatment, etc.)
|Here's me experimenting with techniques I learned in the manual. (Just kidding, it's some other guy.)|
So I know the burning question in all of your minds is: what are the twenty-nine metals? (And for Sanderson fans, what are their Allomantic properties?)
1. Low Carbon Steels
2. Medium Carbon Steels
3. High Carbon Steels
4. 3 1/2% Nickel Steels
5. 4 to 6% Chromium Steels
6. Cromansil Steels
7. Man-ten Steel
8. Cor-ten Steel
9. Yoloy Steel
10. Yoloy Steel
11. R.D.S. Steel
12. Chrome-Vanadium Steels
13. Chrome-Molybdenum Steels
14. Manganese-Vanadium Steels
15. 12-14% Chromium Stainless Steels, 16-18% Chromium Stainless Steels
16. 18% Chrome–8% Nickel Stainless Steel, 25% Chrome–12% Nickel Stainless Steel
17. Stainless Clad Steel
Okay, right now the word "steel" looks like gibberish to me.
18. Austenitic Manganese Steels
19. Cast Steel
20. Cast Irons
21. Malleable Iron
26. Monel Metal
No, Everdur and Herculoy were not just stuck in there to see if you were paying attention; they are actual industry name for metals, copper-silicon-manganese and copper-silicon-tin alloys, respectively.
To weld, you deposit molten metal (usually of the same variety) on the melted surface of the joint.
|This is from learn-how-to-weld.com; the book didn't actually contain any visuals of this.|
Some metals are actually pretty wacky to deal with. Aluminum, for example, does not show any visible change as it melts (you know, like iron turns red, then white hot). Instead, it suddenly collapses when it reaches its melting point.
You should definitely consult this book if you want to arc weld metal. Also if you want to see diagrams entitled "Double Vee Butt Joints– Hands Down Position Coated or Shielded–Arc Electrodes".
