Welder Training and Testing Institute

Welder Training and Testing Institute (WTTI), was founded in 1968 in Allentown, Pennsylvania, and was originally called Breeden School of Welding. In 1973, the school was renamed and the scope of work expanded to include welder training, testing and inspection services for individuals and industry. Ownership of the company shifted to a small welding and management group headed by Robert Wiswesser, who had been an instructor, assistant director and eventually director of the school under the Breeden ownership.The name change was intended to signify a shift in the business from an instructional institution to an organization with a dual mission. Now, WTTI would not only train welders, but also provide industrial services to corporations who needed outside product inspection, testing, welder certification, consulting and in-plant training seminars.
