Heat Treating: Heat Treating Testing and Defects

Heat Treating Testing and Defects builds on the foundational knowledge provided in Heat Treating Processes and Equipment. Presented in THORS’ easy-to-navigate, highly visual, and interactive learning style, Heat Treating Testing and Defects provides application-based knowledge for some of the most common heat treating testing and quality control procedures. In addition, this course will help learners identify and understand the root causes of common heat treating defects, as well as methods to reduce or eliminate such quality problems.
