Tempering Technician Training Certificate
NGA Members $299 / Non-Members $399
Introducing the Tempering Technician Certificate program—a six-course online training for production personnel that walks furnace operators step-by-step through the entire heat-treatment process, training them on tasks and best practices to help ensure high product quality. Developed by the tempering experts of NGA’s Fabricating Committee, the 3.5-hour training is broken down into quick-hit, interactive training segments that can be taken on a smartphone or computer, with a certificate of achievement upon completion of the training and tests. Good for one year upon enrollment, each training can also be quickly referenced on the production floor when completing specific tasks.
