Core Responsibilities

Primary Functions

Interpret complex engineering blueprints, fabrication drawings, weld symbols, and technical specifications to determine project requirements and fabrication sequences.
Accurately lay out, measure, and mark dimensions and reference points on metal stock and plates for cutting, drilling, and forming.
Set up and operate a wide range of fabrication machinery, including plate rolls, press brakes, shears, and ironworkers, to cut and form steel components to required dimensions.
Precisely fit, align, and tack-weld components such as shells, heads, nozzles, manways, and structural supports according to blueprints and layout markings.
Execute high-quality, structurally sound welds using various processes, primarily Flux-Cored Arc Welding (FCAW) and Submerged Arc Welding (SAW), on carbon and stainless steel.
Perform multi-pass welds in all positions (flat, horizontal, vertical, overhead) on thick plate materials, ensuring complete penetration and adherence to Weld Procedure Specifications (WPS).
Operate overhead cranes, jib cranes, and forklifts safely and efficiently to handle and position large, heavy steel plates and fabricated assemblies.
Utilize thermal cutting processes, such as plasma arc and oxy-fuel cutting, for manual and automated cutting of parts and beveling of plate edges for weld preparation.
Grind, chip, and finish welds and surfaces using portable grinders and other hand tools to meet specified aesthetic and quality standards.
Conduct dimensional inspections and quality checks throughout the fabrication process using tools like tape measures, levels, squares, and calipers to ensure accuracy.
Prepare and fit shell courses for automated welding, ensuring proper root opening, alignment, and roundness to maintain tank integrity.
Install and weld internal and external components, including baffles, heating coils, ladders, platforms, and handrails, as specified in the project drawings.
Collaborate with shop supervisors and quality control inspectors to address any fabrication issues, non-conformances, or necessary rework.
Perform routine pre-use inspections and basic preventative maintenance on welding equipment and fabrication machinery to ensure they are in safe, working order.
Adhere rigorously to all company safety policies, procedures, and OSHA regulations, including proper use of Personal Protective Equipment (PPE) and safe material handling practices.
Set up and monitor welding parameters (voltage, amperage, wire speed) on welding machines to achieve optimal results based on the material, thickness, and process.
Assist in the hydrostatic or pneumatic testing of completed tanks and vessels to verify weld integrity and check for leaks, documenting the results as required.
Maintain a clean, organized, and safe work area, contributing to the overall efficiency and safety of the fabrication shop.
Accurately document work performed, track time spent on specific jobs, and complete required production and quality control paperwork.
Work effectively as part of a fabrication team, communicating clearly with fitters, welders, and supervisors to ensure seamless workflow and project completion.

Secondary Functions

Assist with routine shop maintenance, equipment checks, and general housekeeping to ensure a safe and efficient operational environment.
Participate in continuous improvement initiatives by providing practical feedback on fabrication processes, tooling, and shop layout.
Work closely with engineering and quality control teams to clarify ambiguities in blueprints and suggest practical fabrication solutions or improvements.
Engage in daily toolbox talks, safety stand-downs, and other safety meetings to actively promote and maintain a culture of safety and awareness.
