Preface

This is the fourth and final volume of the Eighth Edition of the Welding Handbook. The title of Volume Four is Materials and Applications-Part 2. Publication of this volume not only completes the Eighth Edition, it also concludes publication of the Welding Handbook for the 20th Century.

In this volume, the American Welding Society recognizes those who worked in developing, interpreting, and sharing the technologies described in these editions by serving as chairmen of the Welding Handbook Committee (see facing page).

The Eighth Edition of the Welding Handbook is a fitting tribute to their legacy, as it is the result of thousands of hours of preparation by current volunteers. Originally the Welding Handbook Committee had planned to publish Materials and Applications as a single volume. However, it became evident during compilation of the text that the material was too voluminous to be contained in a single volume. Evidence of this is that the final two volumes exceed 1100 pages, compared to 547 smaller pages in the Seventh Edition.

Volume Four contains ten chapters supplementing the ten chapters contained in Volume Three. Both of these volumes represent a considerable expansion of the information in the previous editions.

In many instances, it is new material never before published by the American Welding Society. One example of new content is the chapter on coated steels. It is 85 pages in the Eighth Edition, compared to 11 in the previous edition.

The chapters on stainless steels, tool and die steels, and titanium also have been revised extensively. The stainless steels chapter provides an overview of ferrite, its effects, and its measurement.

The tool and die steels chapter presents previously proprietary information. The titanium chapter greatly expands the previous treatment of welding metallurgy.

It should be noted that the Welding Handbook is unique, in that it is a far more lengthy dissertation on broader subject areas than other peer-reviewed AWS publications.

Volumes Three and Four of the Welding Handbook have a high level of technical content, yet this material is presented in a manner understandable to typical readers. The authors drew on industry sources to independently confirm that the information represents the latest technology. Volumes Three and Four should stand as authoritative texts for welding information on the vast array of materials welded in the world.

This volume, like the others, was a voluntary effort.

The title page of each chapter bears the names of the Chapter Committee members and the Welding Handbook Committee members responsible for that chapter. Other individuals also participated in a variety of ways, particularly in chapter reviews. Preparation of this volume alone required the collaboration of more than 100 volunteers.

All participants contributed generously of their time and talent, and the American Welding Society expresses its sincere appreciation to them and to the employers who supported their work. They have enabled the Welding Handbook Committee to realize its goal of issuing the Welding Handbook as a peer-reviewed and peer-approved publication.

The Welding Handbook Committee expresses its appreciation to the AWS staff members who assisted with this volume, especially Bill Oates and Alex Saitta for editorial assistance, the Technical Division staff engineers for their technical assistance, and the Publication Services Division staff for graphics assistance.
