Preface

This is the fourth volume of the five volume series f p the 7th Edition of the Weíàing H a w . This volume updates and expands the information on the weldability, brazeability, and solderability of metals and their alloys. Information contained in Volumes 1, 2, and 3 supplements the material presented herein with respect to welding metallurgy, joining processes, testing methods, residual stresses, and distortion.

The order of presentation has changed somewhat from the corresponding volume of the 6th Edition. The information.presented on many metals is more extensive. Chapters covering tool and die steels and commonly uséd, dissimilar metal combinations are now included. Carbon and low alloy steels, stainless steels, and high alloy steels (other than tool and die steels) are grouped in distinct chapters to show their similarities with respect to joining. The reactive metals, titanium, zirconium, hafnium, tantalum, and columbium, are grouped in a chapter for the same reasqm. Another chapter addresses the jojning of nonswctural metals including kryllium, uranium, molybdenum, tungsten, lead, and the precious metais. 

Some of the subjects covered in Section (Volume) i of the 6th Edition will be revised in Volume 5 of this Edition, when published. That volume should be retained until Volume 5 is available. An index of major subjects precedes the volume index. It enables the reader to quickly locate information on a major subject in the current volumes of Welding Handbock, including Volumes (Sections) 1 and 5 of the 6th Edition.
