Flash (Spark) Welder
ふらっしゅ（ひばな）ようせつこう
Industry & Occupation
Classification
Summary
Flash welders are specialists who use electrical resistance to heat and melt the joining surfaces of metal members and join them by applying pressure.
Description
Flash (spark) welders set the joining surfaces of metal parts into a dedicated flash welding machine, combine energization and pressurization to heat and melt them, and integrate them by upset welding. In the work, they clean the surfaces of members, confirm dimensions, and adjust energization time, current value, and pressure settings. They manage sparks and thermal deformation generated during welding, and after welding, perform deburring and quality inspection. Shift work in factories requires knowledge suited to the materials handled, such as steel and aluminum, and the wearing of safety equipment.
Future Outlook
While demand for metal joining in the automotive and electronic components fields remains stable, the introduction of welding robots and automation is advancing, requiring advanced skills and equipment maintenance capabilities.
