Industry & Occupation
Classification
Summary
Specialized technical job that manufactures metal parts by melting and joining base materials at butt positions using arc welding.
Description
Butt welders precisely align base materials such as metal pipes and plates at butt positions, use arc welding machines to melt the metal at high temperatures, supply filler metal while forming beads (weld lines) to join them. This is a specialized profession. To ensure the quality and strength of members used in bridges, piping, mechanical parts, and building structures, they are responsible for a wide range of processes including setting welding conditions, selecting base materials and filler metals, planning welding sequences, post-operation bead inspections, and distortion control. They must be those who have completed special education under the Industrial Safety and Health Act, and perform operations while thoroughly wearing protective equipment, ensuring ventilation, and managing safety.
Future Outlook
While the introduction of robot welding and automation systems is advancing, the demand for skilled workers continues to be high for complex shapes and high-difficulty welding.
