Welder Training and Testing Institute (WTTI) is an American institution focused on welding education and related industrial services. Founded in 1968 in Allentown, Pennsylvania, the organization originated as Breeden's School of Welding and later adopted its current name, expanding from classroom instruction to include hands-on welding training across gas welding and cutting, electric arc welding, and semi-automatic processes. The campus supports in-shop training with a dedicated shop and classrooms, emphasizing practical skills through a structured student-to-teacher ratio and session limits to manage instructional depth. In addition to training, WTTI operates an Industrial Services Division that supplies technicians to corporate clients and a Nondestructive Testing Institute that trains inspectors for the AWS Certified Welding Inspector exam.

Located in the United States, WTTI serves the needs of individuals seeking welding expertise as well as organizations requiring qualified welding personnel and related testing services. The school positions itself within the industrial machinery manufacturing ecosystem by preparing welders to meet rigorous industry standards for quality and safety, while also offering specialized testing and NDT training to support workforce credentialing and inspection capabilities.
