There are two "pocket" resources that I know of, but I don't know that either is still in print.

The Lincoln Arc Welding Company had a publication titled "Metals and How to Weld Them".  Good resource.

Also, from Craftsman Tools, there was a pocket guide to welding that had a lot of info in it.

Check with both groups...perhaps they still provide them.

Try Lincolns web site. They also print a very comprehensive book called the ‘Welding Procedure Handbook’ which is dirt-cheap. If you live in the UK its available from:-

The James F. Lincoln Arc Foundation.
Mansfield Road. Aston,
Sheffield.  S26 2BS
ENGLAND.     Tel 0114 287 2401  

Otherwise use the web site
http://www.lincolnelectric.com/

Weld Pool site gives details of welding procedures for various materials http://home.istar.ca/~bsant/index.html

Very basic guide to arc welding at http://www.meg.co.uk/

Many more links to welding related web sites try  http://www. Gowelding.com

Try your Welding Products Supplier or representative. Here in Australia I have obtained pocket sized handbooks from BOC (British Oxygen Company), WIA (Welding Industries Australia, {a very comprehensive book}), Lincoln, Air Liquide, Strata and, Eutectic-Castolin.

Some of these only have information pertinant to their specific products, however most have oodles of generic information from standards information to techniques and procedures required to deposit a weld to deposition rates and most also have a set of conversion tables in the back.

I would imagine that these would be available around the world with the information structured towards the country of use.
