Summary
A skilled trade that assembles steel frame members and metal structure parts based on drawings and joins them using welding or bolt tightening. Constructs frameworks for architectural and civil engineering structures or industrial equipment on site.
Description
Assembly ironworkers assemble steel frames and metal structural members at construction sites or in factories. They read drawings, measure and level installation positions, temporarily fix with clamps or jacks, and join members using gas welding, arc welding, or bolt tightening. They frequently use cranes and high-place scaffolds, with emphasis on safety management and quality control. They adjust work plans according to site weather and surrounding conditions, collaborating in teams to complete structures.
