Job Title Structural Steel Fabricator and Iron Worker Position Summary Prep and welding of structural steel shapes and plates using MIG and stick welding methods, primarily carbon steel and some stainless steel. Welding in vertical, horizontal or overhead positions. Raise, place, and unite iron or steel girders, columns, and other structural members to form completed structures or structural frameworks. May erect metal storage tanks and assemble prefabricated metal buildings.

Essential Functions

• Read blueprints and drawings and take or read measurements to plan layout and procedures
• Determine the appropriate welding equipment or method based on requirements
• Set up components for welding according to specifications (e.g. cut material with powered saws to match measurements)
• Operate angle grinders to prepare the parts that must be welded
• Align components using calipers, rulers etc. and clamp pieces
• Weld components using manual or semi-automatic welding equipment in various positions (vertical, horizontal or overhead)
• Verify vertical and horizontal alignment of structural-steel members, using plumb bobs, laser equipment, transits, and/or levels.
• Connect columns, beams, and girders with bolts, following blueprints and instructions from supervisors.
• Hoist steel beams, girders, and columns into place, using cranes, or signal hoisting equipment operators to lift and position structural-steel members.
• Bolt aligned structural-steel members in position for permanent riveting, bolting, or welding into place.
• Position girders or other structural-steel using rope to guide them into position.
• Fabricate metal parts such as steel frames, columns, beams, and girders, according to blueprints or instructions from supervisors.
• Pull, push, or pry structural-steel members into approximate positions for bolting into place.
• Cut, bend, and weld steel pieces, using metal shears, torches, and welding equipment.
• Fasten structural-steel members to hoist cables, using chains, cables, or rope.
• Assemble hoisting equipment and rigging, such as cables, pulleys, and hooks, to move heavy equipment and materials.
• Force structural-steel members into final positions, using turnbuckles, crowbars, jacks, and hand tools.
• Erect metal and precast concrete components for structures such as buildings, bridges, dams, towers, storage tanks, fences, and highway guard rails.
• Unload and position prefabricated steel units for hoisting as needed.
• Drive drift pins through rivet holes in order to align rivet holes in structural-steel members with corresponding holes in previously placed members.
• Dismantle structures and equipment.
