  • General laborer or metal shop helper with basic shop exposure

Advancement To:

  • Journeyman Welder / Production Welder
  • Fabricator / Structural Welder
  • Certified Welding Inspector (CWI) or Welding Technician
  • Pipefitter or TIG Specialist
  • Maintenance Technician or Welding Instructor

Lateral Moves:

  • Metal Fabricator
  • Maintenance/Repair Technician
  • Quality Inspector (welding/fit-up)

Core Responsibilities

Primary Functions

  • Assist experienced welders by preparing metal components for welding — including cleaning, grinding, degreasing, removing rust/scale, and ensuring surfaces meet specified tolerances — to produce consistent, code-compliant welds.
  • Perform tack welding and fit-up of assemblies under supervision, using jigs, clamps and fixtures to hold parts in alignment and verify dimensions against engineering drawings and weld blueprints.
  • Operate and set up welding equipment across common processes (MIG/GMAW, TIG/GTAW, SMAW/stick) under guidance, including selecting electrodes/wire, adjusting voltage and amperage, and ensuring proper shielding gas flow.
  • Read and interpret blueprints, welding symbols, part prints and basic fabrication drawings to follow specified weld types, sizes and locations during assembly of components.
  • Measure and inspect parts using precision tools (tape measure, calipers, micrometer, combination square) to verify correct fit-up and alignment prior to welding, and document measurements as required by job packet or work order.
  • Grind, finish and clean welded joints using angle grinders, flap discs and flap wheels to meet smoothness, contour and cosmetic requirements without compromising structural integrity.
  • Prepare and maintain welding coupons and perform test welds for supervisor or quality personnel to qualify settings and procedures before production welding begins.
  • Maintain welding fixtures, consumables and tooling inventory: report low stock, swap gas cylinders safely, and follow storage protocols for fillers, fluxes and electrodes.
  • Adhere to all site-specific and OSHA safety requirements: wear required PPE (helmet, gloves, apron, respirator as required), follow lockout/tagout procedures, and maintain safe work areas free of trip and fire hazards.
  • Assist with oxy-fuel cutting, plasma cutting or mechanical cutting operations to shape parts to rough profiles before fit-up, following cutting specs and thermal-distortion minimization techniques.
  • Document production activities, including weld IDs, process parameters, and completed checklist items in job travelers or digital job tracking systems to support traceability and quality control.
  • Participate in daily toolbox talks and on-the-job training sessions, absorbing feedback from journeymen and foremen to continuously improve weld technique and process knowledge.
  • Assist quality control by performing basic non-destructive test preparation (visual inspection, cleaning for dye-penetrant or magnetic particle inspection) and flagging potential defects for inspection.
  • Support structural assemblies by setting up and aligning subassemblies on weld tables, verifying perpendicularity and squareness, and making minor adjustments to achieve dimensional tolerances.
  • Maintain equipment: clean welding guns, nozzles, liners and contact tips; perform routine checks on regulators, hoses, torches and grounding connections to ensure safe, reliable operation.
  • Follow welding procedure specifications (WPS) under supervision, including preheat and interpass temperature controls, to meet metallurgical and code requirements for the material being welded.
  • Assist with brazing, soldering or mechanical fastening as required for assemblies that combine welding and other joining methods, learning appropriate filler metals and flux selection.
  • Learn and apply basic metallurgy: identify common steels and alloys, understand their weldability, and follow recommended weld parameters to minimize cracking and distortion.
  • Troubleshoot common welding issues under guidance — such as porosity, lack of fusion, excessive spatter or warping — by adjusting technique, parameters or fit-up and consulting senior welders.
  • Conduct housekeeping of the welding area: remove slag, dispose of scrap to designated containers, keep walkways clear and maintain a clean, organized workspace to support safety and efficiency.
  • Support production scheduling by staging materials, assisting with part movement and communicating status updates to foremen so deadlines are met and rework is minimized.
  • Learn and maintain compliance with industry codes and standards commonly used in the facility (e.g., AWS, ASME, company-specific welding standards) and assist in preparing parts for final certification.
  • Assist with basic heat treatment or post-weld processing tasks (stress relief, controlled cooling) under supervision to meet mechanical property or distortion control requirements.
  • Participate in continuous improvement activities by suggesting small process changes, reporting repetitive defects, and contributing to a safer, more efficient welding environment.

Secondary Functions

  • Attend formal classroom training, certification courses and on-the-job mentorship to advance technical competency and prepare for journeyman status.
  • Collaborate with layout personnel and machinists to confirm part geometry and prepare items for final assembly.
  • Support ad-hoc maintenance requests for welding equipment and collaborate with shop maintenance staff for repairs or replacements.
  • Help track consumables usage and recommend ordering adjustments to supervisors to prevent production delays.
  • Assist in maintaining welding procedure documentation, updating job travelers and helping ensure traceability of materials and weld records.

Required Skills & Competencies

Hard Skills (Technical)

  • Proficiency or demonstrable training in basic welding processes: MIG (GMAW), TIG (GTAW) and Stick (SMAW).
  • Blueprint and welding symbol reading — ability to interpret weld type, size, length, and location from fabrication drawings.
  • Basic measuring and layout skills: tape measure, calipers, micrometers, squares, levels and protractors for fit-up verification.
  • Familiarity with welding equipment setup: power sources, wire feeders, regulators, hoses and ground connections.
  • Knowledge of common filler metals, electrode selection and shielding gas choices for carbon steel, stainless and aluminum.
  • Basic understanding of welding codes and standards (AWS fundamentals, elemental ASME awareness) and following WPS under supervision.
  • Grinding, finishing and surface preparation skills (angle grinders, flap discs, deburring tools).
  • Safe handling and storage of gas cylinders, welding consumables and hazardous materials; basic understanding of PPE and respirator use.
  • Hands-on experience or training in oxy-fuel and plasma cutting, and basic mechanical cutting methods.
  • Basic nondestructive testing preparation knowledge: visual inspection, surface prep for dye-penetrant and magnetic particle tests.

Soft Skills

  • Strong attention to detail and a meticulous approach to fit-up, weld quality and final inspection criteria.
  • Willingness to learn, receive feedback and progress through structured apprenticeship or certification steps.
  • Good communication and teamwork — ability to follow instructions from journeymen and coordinate tasks with fabricators and inspection teams.
  • Problem-solving mindset: identify and escalate issues, suggest practical adjustments, and adapt welding technique under mentorship.
  • Time management and reliability — meet production schedules, arrive prepared, and manage assigned work efficiently.
  • Physical stamina and manual dexterity for repetitive welding tasks, material handling and sustained focus in noisy/industrial environments.
  • Safety-first attitude with consistent compliance to procedures, hazard recognition, and proactive reporting of unsafe conditions.
  • Adaptability to changing priorities, work orders and part specifications in a dynamic fabrication environment.
  • Professionalism and a customer-oriented mindset when working on client-specific or certified projects.
