Yakiita Worker (Metal Heat Treatment)
やきいたこう
Industry & Occupation
Classification
Summary
Specialized manufacturing technician responsible for the heat treatment process of heating and cooling metal parts and tools to control their physical properties.
Description
Yakiita workers (metal heat treatment) perform operations to heat metal products and parts to appropriate temperatures and then control cooling to enhance and manage physical properties such as hardness and toughness. They mainly operate heat treatment furnaces such as quenching furnaces, normalizing furnaces, and tempering furnaces, managing temperature, atmosphere adjustment, and selecting cooling methods. After processing, they conduct inspections such as hardness measurement and microstructure observation to confirm quality. This is an important process in factory production lines, requiring high attention to detail, specialized knowledge, and physical stamina.
Future Outlook
With increasing demand for high-performance parts in automobiles, aircraft, electronic devices, etc., the need for precise heat treatment technicians remains stably high. As smart factories advance with IoT, there is a trend toward requiring skills in process monitoring and automation.
