Dear Randy:
There is a book titled "Welding steels without hidrogen cracking" by Bailey et Al. In this book you can obtain information about safes procedures (preheat, heat imput, post'heat, etc.) for weld medium carbon steels, high carbon steels and alloy steels developed by The Welding Institute. You can get information about this book from Woodhead Publishing Limited: www.woodhead-publishing.com
I hope this help you.
