Foreword

(This Foreword is not a part of AWS D1.6:1999, Structural Welding CodeStainless Steel, but is included for

information purposes only.)

This code covers the requirements for welding stainless steel components other than pressure vessels or pressure pip-

ing. For many years, fabrications involving stainless steel welding have used ANSI/AWS D1.1, Structural Welding

CodeSteel, to provide the requirements for quality construction. However, as the D1.1 document is written for the car-

bon and low alloy steels commonly encountered in structural fabrication, it does not explicitly address the unique re-

quirements of the stainless steels. The AWS D1 Structural Welding Committee thus recognized the industry need for a

D1.1 analogue designed for the welding of stainless steel wrought and cast shapes and plates.

The most noticeable feature of D1.6:1999 is the allowance of prequalified Welding Procedure Specifications (WPSs)

for the austenitic stainless steels. This exemption from qualification testing is based on considerable experience with the

most widely used stainless steels.

The D1.6 Code is the product of a pool of experts arriving at a consensus position, in keeping with the American

National Standard Institutes requirements. Like all prototype documents, D1.6:1999 is acknowledged by the D1 sub-

committee on stainless steel as being subject to considerable scrutiny by industry. Criticism, comments and suggestions

are welcomed by AWS as a means to improve the technical and economical aspects of the D1.6 provisions. Requests

for official interpretations, comments or suggestions should be sent to the Secretary, Structural Welding Committee,

American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126.
