Core Responsibilities

Primary Functions

Interpret and analyze complex engineering drawings, blueprints, 3D models, sketches, and work orders to determine project requirements, material specifications, and the precise sequence of fabrication operations.
Set up, calibrate, and operate a wide range of fabrication machinery, including CNC press brakes, hydraulic shears, laser cutters, plasma cutters, and turret punches, to accurately cut and form sheet metal.
Execute precise bending and forming operations, calculating bend allowances and deductions, and selecting the correct tooling and dies to achieve specified angles and radii without compromising material integrity.
Perform various welding processes, primarily TIG and MIG, to join and assemble metal components, ensuring welds are strong, clean, and meet both structural and aesthetic standards.
Skillfully use hand and power tools such as grinders, sanders, buffers, and drills to deburr, finish, and prepare fabricated parts for subsequent processes like painting, powder coating, or plating.
Conduct rigorous in-process and final quality inspections using precision measuring instruments including digital calipers, micrometers, protractors, and height gauges to verify parts conform to dimensional tolerances.
Lay out, measure, and mark dimensions and reference points on sheet metal stock according to blueprints or templates, ensuring optimal material usage and minimal waste.
Assemble complex metal structures and components by fitting, aligning, and securing parts using welding, bolting, and riveting techniques.
Troubleshoot and resolve fabrication issues as they arise, adjusting machine settings, modifying techniques, or consulting with engineering to address design or material challenges.
Manage workflow and prioritize tasks effectively to meet tight production schedules and deadlines without sacrificing quality or safety.
Read and understand job travelers and production orders to ensure all required materials, processes, and specifications are correctly followed for each unique job.
Operate forklifts and overhead cranes safely to handle and transport large sheets of metal and heavy fabricated assemblies within the facility.
Select appropriate gauges and types of sheet metal (e.g., stainless steel, aluminum, carbon steel) based on project specifications and technical requirements.
Perform routine checks and preventative maintenance on fabrication equipment to ensure operational readiness, safety, and longevity, reporting any malfunctions for repair.
Program or input parameters into CNC-controlled machinery, making necessary adjustments to offsets and settings to maintain accuracy throughout a production run.
Fabricate custom components and one-off prototypes for research and development projects, working closely with engineers to refine designs.
Ensure all finished products are properly identified, stacked, and protected to prevent damage during handling and transportation.
Maintain a clean, organized, and safe work area by adhering to 5S principles and all company safety policies and OSHA regulations.
Document production activities, including materials used, time spent, and parts completed, accurately in the company's ERP or production tracking system.
Collaborate with other team members, including welders, machinists, and assemblers, to ensure a smooth and efficient production flow from start to finish.

Secondary Functions

Mentor and provide guidance to apprentices or less experienced fabricators, sharing knowledge of techniques, machinery, and safety protocols.
Participate actively in continuous improvement initiatives and lean manufacturing events to enhance efficiency, reduce waste, and improve overall quality.
Assist the materials handling team with inventory counts and organization of raw metal stock to ensure accurate records and availability.
Serve as a member of the shop's safety committee, contributing to safety audits, risk assessments, and the development of improved safety procedures.
