The ferritic/austenitic duplex stainless steels (DSSs) discussed in AWS D10.18M/D10.18:2018 have proven to be weldable using proper welding procedures. The processes GTAW, GMAW (includes all transfer modes), SMAW, FCAW, and SAW have all been used with success on these alloys. Automatic and mechanized welding such as orbital welding with the GTAW, GMAW, and FCAW processes have also been used with success on duplex alloys. Manual welders that have experience with austenitic stainless steels should be able to apply many of the techniques they have learned from these alloys to the welding of duplex stainless steels, while of course keeping in mind the exceptions to be noted within this document.
Provides an introduction to all of the important topics in welding engineering. It covers a broad range of subjects and presents each topic in a relatively simple, easy to understand manner, with emphasis on the fundamental engineering principles.
Math for Welders is a combination text and workbook designed to help welding students learn and apply basic math skills. The basic concept behind each math operation is explained at the opening of the unit. Next, students are given clear instruction for performing the operation. Each unit includes a variety of welding related practice problems to reinforce what the students have learned. The practice problems are identical to the types of problems the students will be required to solve in a welding shop. In addition to teaching basic math concepts, the problems give students a preview of the types of challenges they will face in a work environment. This helps the students develop solid troubleshooting skills that will serve them throughout their careers as welders.
An authoritative source of reference on every aspect of thermal welding and associated cutting processes. Each process is examined clearly and comprehensively from first principles through to more complex technical descriptions suited to those who need more technical information. Copiously illustrated throughout and with an extensive glossary of terms, this book is essential reading for welding and production engineers, metallurgists, designers, quality control engineers, distributors, students and all who are associated with the selection and application of equipment and consumables.
