16 September 2013 - Resources on Duplex Stainless Steel - Bulletin 89
Mid September Bulletin
A thorough treatment of welding Duplex Stainless Steels (DSS) is found in AWS Welding Handbook Ninth Edition, Vol. 4 - Materials and Applications, Part 1, pages 351-368.
The subject of this Bulletin was dealt with in an Article on Duplex Stainless Steels - Best Practices for Selection and Welding, published (2) in the last issue of Practical Welding Letter for September 2013. Click on PWL#121 to see it.
Following a feedback message from a kind reader, we are preparing a thorough follow up note, to be published in the next issue of practical Welding Letter for October 2013.
It will include description and reference standards for additional testing to be used for qualifying Duplex Stainless welding Procedures.
Also to be used for validating current welding operations against results documented in Procedure Qualification Records (PQR).
As promised in the article, we publish here a list of knowledgeable Online Sources likely to provide to our readers useful insight and information on the subject.
If the sources are commercial companies, no endorsement or recommendation of their products is intended. Interested readers are urged to check on their own if any of the manufacturers' recommendations is worth their attention for their specific circumstances.
The addresses reported hereafter were live and correct at the time of their publication. There is no guarantee that they will always be so, because they are administered by the sources themselves and are under their control.
Note: References to articles or other documents are given here in one of two forms. If the links are "live" (usually underlined or otherwise highlighted) they are operated with a click of the mouse.
If they are URL's (Uniform Resource Locator), which is the analogue of an address, they begin with "http://..." or "www.". These are not live and must be copied and pasted entirely into the browser (after having selected them with the mouse or otherwise).
If they are long they may be displayed in two or more lines. In that case one has to care that the URL be copied completely in a single line without any space, and Enter.
If the information is important to you, you may save the selected pages in a suitable folder on your Computer for easy reference. You are welcome to forward this page to those of your friends who may profit of this information.
