Dan has an extensive background in brazing engineering, with more than 50-years of hands-on experience in that field.

As a respected expert in brazing, Dan has become known worldwide as an excellent seminar leader, trainer and speaker, just one example of which was demonstrated when he was presented with the Materials Engineering Institute Instructor of Merit Award by ASM International for "..excellence in technical expertise, presentation skills, and quality support materials..".

Dan travels regularly around the US each year, and to many other countries of the world, not only teaching brazing seminars and conducting in-house brazing-training programs (as mentioned in more detail below in the "Background" section), but also visits many companies as a consultant and problem-solver. As a well-versed brazing auditor, Dan helps companies determine if they are doing the correct things to ensure good brazing of components in their operations.

Dan has published numerous articles on the subject of brazing in leading journals in the brazing/welding/heat-treating field, a partial listing of which appears below in the section entitled "Publications". These articles have been well received, especially by those who are responsible for running brazing-plant operations, and have generated many positive comments.

Dan also regularly publishes brief brazing articles on this website, as well as on several other blog-sites, including those hosted by Industrial Heating magazine. These articles can be seen in the "Brazing Articles" tab shown at the top of this page.

Dan's extensive knowledge and experience in brazing has also proven useful over the years when companies are seeking an "Expert Witness" in legal matters between themselves and their workers, suppliers, or customers. Dan's understanding of brazing has enabled clients to bring about resolution to their legal issues, usually without having to go inside a courtroom.

Dan has been operating his own brazing consulting and training business for the last 25-years.

Background and Capabilities:

Brazing Training -- Dan has conducted intensive brazing-engineering training seminars for more than 50-years, and continues to do so. These brazing training seminars (varying in length from 1-day to 5-days) are taught each year around the U.S., Canada, Mexico, and several Pacific-basin countries, consisting of regionalized general brazing seminars, as well as intensive in-house specialized training seminars for individual companies, based on their particular needs.

In the past, for many years, Dan conducted semi-annual 3-day furnace brazing seminars in Detroit for Wall Colmonoy along with Robert Peaslee, taught an ASM Brazing Fundamentals course in Materials Park, Ohio, and prior to that, many 3-day torch brazing seminars several times each year while employed at Handy & Harman.

Consultant -- Dan currently visits many companies each year, reviewing and auditing their brazing operations so as to help them define solutions to their brazing and metals-joining problems.

Communicator -- Dan speaks several times each year before trade, civic, and church groups, meetings ranging in size up to several thousand people.

Trade Shows -- He has participated in many shows around the world during the last 50 years, as a technical speaker, as technical-session chair, as host at hospitality suites, and working in booths on the trade show floor.

Brief Brazing Career Chronology:

Kay & Associates, Simsbury, CT. (1996 -- present)
-- The leading US provider of non-biased brazing training programs, audits, and brazing consulting and problem solving.  Kay & Associates (K&A) was purchased in August , 2023, by Prince & Izant Company (P&I), a major brazing products/services supplier to the industry worldwide.  This new P&I/K&A relationship allows the highly effective and meaningful training programs that have been conducted by K&A for almost 30-years to continue into the future.

-- Dan will continue to be (as a part of P&I) a leading, independent consultant/trainer to the brazing industry on all aspects of brazing engineering, business development, strategic planning, and development of in-house technical expertise for brazing problem solving and problem prevention. Dan's training programs vary from hands-on training in torch and furnace brazing to large brazing forums at hotels around the world.


Wall Colmonoy Corporation, Madison Heights, MI. (l980--1995)
(Manufacturer of nickel-alloy powders for furnace brazing and thermal-spray, and a high temperature heat treat and brazing processor of metal parts)

-- While at WCC, Dan held various operating postions, including: Asst. Vice President of Manufacturing (he was responsible for overall operations at all five of WCC's Nicrobraz Division processing plants around the US; plant general manager for the Detroit Processing Plant (this plant manufactured all the company's brazing products, and also had numerous vacuum and atmosphere furnaces for commercial brazing and heat-treating operations); Brazing Products Manager (world-wide); and also was the director of the Brazing Engineering Center (WCC's Detroit-based R&D center for development of brazing products and applications for same).


Handy & Harman, New York, N.Y. (l974--l980)
(Leading manufacturer, supplier, and refiner of precious metal alloys)

-- Brazing Products Engineer. Dan was the head brazing engineer on corporate engineering staff involved in customer liaison, brazing-training, new product development, and the marketing and advertising for the brazing product line. Also responsible for trade show development, salesmen training, and problem solving for customers.
