Core Responsibilities

Primary Functions

Read, interpret and verify engineering drawings, blueprints, welding symbols, material lists and work orders to plan and execute fabrication and welding activities with accuracy and compliance to specifications.
Set up, program (where applicable), and operate welding equipment including MIG (GMAW), TIG (GTAW), Stick (SMAW), and flux-cored (FCAW) machines to produce high-quality welds on carbon steel, stainless steel and aluminum components.
Perform fit-up, tack welding and full-penetration welds on structural components, plate work, piping spools, frames and assemblies while maintaining correct joint alignment, dimensions and tolerances.
Execute welding in accordance with approved Welding Procedure Specifications (WPS), procedure qualifications and industry codes such as AWS D1.1, ASME Section IX and other client-specific standards.
Conduct pre-weld preparation including cutting (plasma, oxy-fuel), beveling, grinding, cleaning, and dimensional layout to ensure proper joint preparation and fit.
Use jigs, fixtures, clamps and alignment tools to ensure repeatable, accurate fabrication and to reduce rework and welding distortion on assemblies.
Perform tack inspection and dimensional verification using measuring tools (calipers, tape, square, level) and document results on traveler sheets or production records.
Carry out weld inspection and quality checks including visual inspection, acceptance criteria verification, and documenting non-conformances for rework or NDE.
Execute basic nondestructive testing support tasks (visual inspection, magnetic particle testing (MT), dye penetrant testing (PT)) and coordinate with certified NDT technicians for advanced testing (UT, RT) as required.
Operate metal cutting and forming equipment (shears, rollers, press brakes, plasma cutters) to produce components that meet drawing specifications.
Grind, clean and finish welded joints to meet surface finish, clearance and cosmetic requirements and prepare parts for coating or assembly.
Maintain and adjust welding parameters (amperage, voltage, wire feed speed, shielding gas) to optimize penetration, bead profile and weld integrity for varying material thicknesses and positions.
Record weld data, heat input, filler materials and consumables usage for traceability and compliance with project and quality documentation.
Collaborate with engineers, estimators and production planners to review drawings, propose fabrication methods, identify cost-saving modifications and sequence work for efficient throughput.
Troubleshoot welding defects, distortion and fit-up issues, identify root causes, and implement corrective actions to prevent recurrence and improve first-pass yield.
Maintain personal and shop safety by following PPE requirements, lockout/tagout procedures, fire prevention controls, and site-specific hazard protocols; participate in toolbox talks and safety audits.
Keep welding equipment and tools in serviceable condition by performing routine cleaning, maintenance, electrode and nozzle replacement, and arranging for repairs when required.
Assist with material handling, staging and inventory control of consumables, plate stock and fabrication components; operate overhead cranes, forklifts or hoists as certified.
Mentor and train junior welders, apprentices and temporary staff on best practices, welding technique and safe operation of equipment.
Prepare finished assemblies for shipping or installation by packaging, dimensionally verifying and completing required documentation such as COCs, weld maps and material traceability records.
Participate in continuous improvement initiatives, lean manufacturing practices and Kaizen events to reduce waste, lower cycle times and improve product quality.
Adhere to customer-specific requirements, inspection plans and documentation processes including completing travelers, test reports and inspection checklists for each work order.
Support emergency or priority jobs by reorganizing workloads, performing overtime work as needed and communicating status updates to supervisors and project managers.

Secondary Functions

Assist in the development and revision of Welding Procedure Specifications (WPS) and work instructions based on field feedback and inspection results.
Support procurement and inventory reconciliation for welding consumables, rods, wires, gases, and PPE to maintain uninterrupted production.
Provide detailed input for job estimates, lead times and resource planning by communicating typical fabrication yields and man-hour requirements.
Liaise with QA/QC and project engineers to coordinate in-process and final inspections, ensuring corrective action items are closed on time.
Participate in cross-functional training to expand shop flexibility, including basic fit-up, pipe threading, or assembly line tasks.
Maintain accurate electronic or paper records of certification expirations, welding qualification tests and training completions.
Help implement and sustain shop housekeeping and 5S standards to improve safety and productivity.
Support site installation teams by providing fabrication guidance, fit-up templates and as-built adjustments when needed.
