Industry & Occupation
Classification
Summary
A technical job that applies heat treatment to metal materials and parts to optimize mechanical properties such as hardness and toughness.
Description
Annealers (metal heat treatment) heat metal products and parts to a specified temperature, hold them for a certain period, and then slowly or rapidly cool them to remove internal stresses and improve the material's hardness and toughness. They properly measure furnace temperatures and control the atmosphere to ensure product quality. The work involves handling heavy objects using cranes or hoists and working in high-temperature environments, making safety management and quality inspection crucial.
Future Outlook
With the diversification of materials and development of high-performance materials, the demand for precise heat treatment technicians is increasing. Amidst advancing automation and IoT in equipment, acquiring data analysis and maintenance skills is also required.
