Core Responsibilities

A Highway Welder's day-to-day activities are focused on ensuring the structural integrity and safety of public infrastructure.

Primary Functions

  • Execute high-quality welds on structural steel components for bridges, overpasses, and support structures using Shielded Metal Arc Welding (SMAW) and Flux-Cored Arc Welding (FCAW) processes.
  • Interpret complex engineering blueprints, shop drawings, and Welding Procedure Specifications (WPS) to accurately determine project requirements and welding parameters.
  • Perform all-position welding (flat, horizontal, vertical, overhead) on various metal types and thicknesses, often in exposed, outdoor field conditions and at significant heights.
  • Set up, calibrate, and operate a variety of welding equipment, including multi-process power sources, wire feeders, and gas flow regulators, ensuring optimal performance.
  • Utilize air carbon arc gouging, plasma cutting, and oxy-fuel torches for precise metal cutting, joint preparation, beveling, and the removal of defective welds.
  • Expertly weld and repair crucial structural elements like steel girders, beams, columns, and decking in strict accordance with the AWS D1.5 Bridge Welding Code.
  • Install, repair, and weld metal guardrails, sign gantries, and other roadside fixtures to meet or exceed Department of Transportation (DOT) and federal highway standards.
  • Conduct thorough visual inspections of all welds to identify and remediate defects such as porosity, undercut, or lack of fusion, ensuring compliance with stringent quality control standards.
  • Operate rigging and provide clear hand signals for crane operators to safely move and position heavy steel components into place for fabrication and welding.
  • Fabricate and assemble metal structures by cutting, bending, and fitting components with precision prior to performing final welding operations.
  • Adhere rigorously to all site-specific and OSHA safety protocols, including lockout/tagout procedures, fall protection plans, and confined space entry permits.
  • Weld reinforcing steel (rebar) splices and assemblies for cast-in-place concrete structures, ensuring proper alignment and structural bond.
  • Meticulously grind and prepare surfaces and joints for welding, removing rust, mill scale, and other contaminants to ensure a pristine surface for a quality weld.
  • Work effectively and safely from aerial lifts, man baskets, and complex scaffolding systems to access work areas on large and complex bridge structures.
  • Maintain accurate and detailed daily logs of work performed, materials consumed, and equipment status to support project documentation and tracking.
  • Collaborate effectively with ironworkers, riggers, crane operators, and other tradespeople on the job site to coordinate tasks and ensure seamless project execution.
  • Perform post-weld heat treatment (PWHT) operations as dictated by project specifications to relieve residual stresses and improve the mechanical properties of the weldment.
  • Complete all work in full compliance with federal, state, and local building codes, as well as company-specific quality assurance and safety policies.
  • Operate stud welding equipment to install shear connectors on composite bridge decks, ensuring a strong bond between steel beams and the concrete slab.
  • Measure, lay out, and mark workpieces using straightedges, squares, and measuring tapes to ensure precise cuts and fits for complex assemblies.

Secondary Functions

  • Assist in job site setup, material staging, and daily cleanup activities to maintain a safe, organized, and efficient work environment.
  • Actively mentor and provide on-the-job guidance to welder apprentices and helpers, fostering the development of the next generation of skilled tradespeople.
  • Participate in and contribute to daily safety briefings ("toolbox talks"), actively identifying and discussing potential hazards and mitigation strategies.
  • Support the on-site management of materials and inventory, tracking the usage of welding consumables, gases, and other essential supplies.
