A header operator is a metalworking professional that operates a cold heading machine. Heading is a process that includes forging, extruding and upsetting in one, allowing you to expedite the production of products like bolts, screws, and lug nuts. Your duties as a header operator include loading the materials into the machine and conducting the proper ratioing process, ensuring that the final product is not victim to buckling. Diameter ratio is generally consistent at 3:1, but you must be able to adapt to different situations, changing the ratio when necessary. Header operator is a more advanced position that requires machinery skills. While there are no post-secondary academic qualifications, it’s essential to have several years of metalworking experience before transitioning to a header operator career.
