In metalworking, heat treating describes a variety of techniques and processes of heating materials for the purposes of hardening, tempering, or annealing a material, such as glass or metals like steel or copper. As a heat treat supervisor, your duties are to supervise and coordinate other heat treating equipment setters, operators, and tenders, ensuring their work meets the required technical specifications and is completed promptly. Your responsibilities also include training new operators and processors and overseeing their activities until they become familiar with the machinery and heat-treating processes the facility utilizes.
