Sun Mon Tue Wed


These two Sunday seminars require separate registration at an additional cost to the regular IBSC program. Cost for either the morning seminar or the afternoon two-part seminar is $225 each ($195 for members). Cost for the full day of combined seminars is $385 ($325 for members).

Fundamentals of Brazing
Tom Sandin, Business and Applications Manager, WESGO Metals
9:00 am - 12:00 pm

This seminar presents the basics of brazing, including the fundamentals of wetting, spreading, contact angles, surface oxides and cleanliness. The advantages and disadvantages of brazing, and its critical steps and manufacturing issues will be covered. Principles related to joint design, fixturing, joint clearance, and thermal-expansion mismatch will be presented, and cleaning, filler metal selection, and methods of applying will also be reviewed. Cleaning and protection of the joint and filler metal during brazing using fluxes and atmospheres will be described, as well as heating sources such as oxyfuel, induction, resistance, molten flux, radiant, convection, laser and electron beam. Destructive and nondestructive inspection, codes and standards, and health and safety issues will be summarized.

Fundamentals of Brazing is intended for engineers and supervisors who need a basic knowledge of brazing for research, manufacturing and the planning, management, or supervision of these operations. Beginning practitioners and technicians who need to be introduced to braze joining, and entry –level and supervisory personnel who are responsible for brazing also benefit from the material that will be covered.

About the Speaker:
Tom Sandin has 32 years braze industry experience, primarily in aerospace jet engines and related components, leading New Product Development for jet engine repairs and DER approval. Tom was also a General Manager for a commercial braze shop serving the medical, semi-conductor, power generation and marine industries. Commercial atmosphere and vacuum furnace brazing of ceramics, ferrous metals, nonferrous metals, aluminum and alloy metals. As Wesgo’s Business & Applications Manager, Tom is developing opportunities for new alloys in braze and other applications. He holds two patents related to brazing processes and alloys.

Brazing Processes and Applications - Part I
Ceramic Brazing
Dr. Toshi Oyama, Development Manger, WESGO Metals, Morgan Advanced Ceramics
1:00 pm - 2:00 pm

This course presents the basics of brazing involving ceramic materials. After brief introduction of the history of ceramic brazing, a conventional process involving metallizing-and-brazing is described. The course then discusses active metal brazing process where ceramic material is directed brazed by using active brazing filler metals. Key parameters for reliable ceramic brazing are explained in detail, using technical data and application examples.

The material covered in this course enables you to understand the basic principles of ceramic brazing, and to use them to brazing ceramic applications.

The Ceramic Brazing seminar is intended for engineers and supervisors who need a basic knowledge of ceramic brazing and for engineers, supervisors, and operators who are involved in ceramic brazing.

About the Speaker:
Dr. Oyama received a M.S. and Ph.D. in Material Science and Engineering Department, Stanford University, where he studied creep deformation of metals, specifically on superplastic properties of ultra-high carbon steels. Since joining WESGO Metals in 1987, he has been involved in all aspects of technical activities at WESGO Metals. He plays a key role in new product and process developments. The process development involves casting, rolling, powder metallurgy as well as melt-spinning technologies. He is the author of over 30 technical papers and four patents. He lectured in many technical conferences. He is a member of the ASM International, American Welding Society, and Japanese Welding Society.

Brazing Processes and Applications - Part II
Brazed Joint Design and Allowables
Dr. Yury Flom, Materials Engineer, NASA Goddard Space Flight Center
2:00 pm - 4:15 pm

At the present time an industry standard methodology for design and analysis of the brazed joints has not been developed. This seminar will address the strength of the brazed joints, the methods of mechanical testing and our ability to evaluate the margins of safety of the brazed joints as it applies to the design of critical and expensive brazed assemblies. Mechanical engineers responsible for design and stress analysis of the brazed structures will benefit the most from attending the Brazed Joint Design and Allowables seminar.

About the Speaker:
Dr. Yury Flom has over 23 year of experience working in the Materials Engineering Branch at NASA Goddard Space Flight Center. Prior to that he was working in power industry. Most of his carrier Dr. Flom has been involved in failure analysis investigations, materials selection and testing, welding and heat treatment. His experience includes the support of all major Goddard flight missions launched between 1985 and 2008 as well as evaluation and troubleshooting of the Ground Support Equipment and the Center Facilities. He was responsible for the materials evaluations in over 19 Mishap and Close Call Investigation Teams at Goddard and NASA-wide. In 1999, he established a vacuum brazing laboratory at Goddard and has been providing brazing services to all Goddard flight projects and research activities. He designed and built an Electron Beam brazing system capable of brazing tubular assemblies. Dr. Flom represents NASA on AWS C3 Brazing and Soldering Committee and is teaching a graduate course on brazing at Ohio State University. Dr. Flom obtained his B.S. in mechanical and welding engineering from Kiev Polytechnic Institute and M.S. and Ph.D. in Material Engineering from the University of Maryland.
