Session W11: Welding Symbols Workshop
Richard Campbell, Bechtel Fellow & Welding Technical Specialist
AWS welding symbols are a great communication tool, but are quite often misunderstood. While designers typically know what weld joint or weld they want, the welding symbol they place on a drawing is often either drawn incorrectly or is misinterpreted by the welder making the weld. Furthermore, many welding inspectors do not fully understand welding symbols and as a result may be misinspecting welds. The goal of this seminar is to provide a good understanding of AWS welding symbols, with explanations of their proper and improper use. This seminar is geared for all involved with welding symbols – from designers who place them on drawings, to the welders who know what the designer wants (regardless of what the symbol says), to the welding inspector who has to verify that the final weld meets the welding symbol requirements. It will also be great for new engineers who do not have experience with symbols, shop and field supervisors, and anyone else involved in manufacturing and welding. Examples of welding symbols which frequently trip up users and of real-life samples are provided.
Session W12: The Why and How of Welding Procedure Specifications Workshop
Scott Helzer, American Welding Society
As a welding professional who is constantly responding to customer demands for increasing the performance and quality of weldments while controlling costs, optimizing your WELDING PROCEDURE SPECIFICATIONS (WPSs) for performance and profitability SEMINARS may be the key. A well written WPS Defines, Measures, Analyzes, Improves, & Controls (DMAIC) quality in the welding process. This two-part workshop will begin by comparing and contrasting CSA W47.1, W59 and D1.1. The balance of the morning presentation is focused on fundamentals of WPSs for both the seasoned professional and for those individuals seeking to become more proficient in the authoring and application of a WPS in fabrication as well as a hands on approach to advanced instruction in the formulation and writing of WPSs in the afternoon.
W13: Aluminum Welding Technology Workshop
Frank Armao, Lincoln Electric Company
This workshop will inform on the advances in Aluminum Welding technology by exploring new process, equipment, and support materials. Attendees will also be interested in improving performance of their products thru a discussion on materials used, joint preparation, alloys, wire size, packages, and welding gases. A question and answer period will be allowed to address specific problems. The main goal is to improve the competitive advantage and reduce costs in producing quality aluminum welds.
Session W15: Resistance Welding
Menachem Kimchi, The Ohio State University
As new and advance materials are being deployed in the manufacturing industries, welding and joining present a major challenge to engineers and technicians involved in product design and manufacturing. The automotive industry is a prime example in applying these advanced but sometimes difficult to weld materials.
This resistance welding course is designed to provide the participants with complete understanding of the resistance welding processes and relate it to the welding of these advance state of the art materials. The course will cover a range of topics, from basic material and process concepts to solving production and product quality problems.
W22: Metallurgy Applied to Everyday Welding Workshop
Scott Helzer, American Welding Society
Although metallurgy is a standard subject in general engineering, it doesn’t provide the information that welding professionals need in controlling weld and heat affected zone properties. This workshop starts with coverage of physical metallurgy, serving as a solid refresher or a clear introduction and move into the metallurgy of welds in carbon and low-alloy steels. This short course will help you understand how welding affects the properties of base materials, and the performance issues caused by welding resulting in discontinuities and defects.
