Fabricator

The Fabricator is responsible for measuring, marking, cutting, beveling, fitting, assembling, aligning, and preparing piping components, structural steel, storage tank components, equipment supports, and other fabricated assemblies in accordance with approved engineering drawings, isometric drawings, material specifications, dimensional tolerances, and project quality requirements.

The role involves coordinating with welders, pipe fitters, riggers, QA/QC inspectors, and supervisors to ensure that fabricated components meet the required dimensional accuracy, material traceability, fit-up quality, safety, and production targets.

3. Key Responsibilities
A. Fabrication and Assembly Activities
Perform fabrication activities for piping spools, structural steel assemblies, pipe supports, brackets, platforms, frames, skids, and other project components.
Read and interpret fabrication drawings, piping isometric drawings, general arrangement drawings, assembly drawings, and shop sketches.
Measure, mark, cut, prepare, fit, and assemble materials according to approved drawings and specifications.
Fabricate carbon steel, stainless steel, alloy steel, and other specified materials according to project requirements.
Carry out layout, marking, setting out, and dimensional measurement before cutting or assembly.
Ensure correct orientation, dimensions, elevations, angles, and alignment of fabricated components.
Perform tack fitting and assembly preparation in coordination with qualified welders and fitters.
Maintain correct joint gaps, bevels, root faces, offsets, and alignment according to approved drawings and welding requirements.
Use clamps, jigs, fixtures, wedges, and other approved tools to maintain dimensional accuracy during assembly.
Prevent distortion, damage, and unnecessary material wastage during fabrication.
Coordinate fabrication sequences to minimize rework and improve productivity.
Complete assigned fabrication activities within the approved work schedule without compromising quality or safety.
B. Drawing Interpretation and Measurement
Read and understand piping isometric drawings, fabrication drawings, spool drawings, structural drawings, and material details.
Identify pipe sizes, nominal pipe diameter (NPS/DN), wall thickness, material grades, fitting types, flange ratings, and component specifications.
Understand dimensions, center-to-center measurements, face-to-face dimensions, elevations, offsets, and orientations.
Identify weld joint locations, branch connections, reinforcement requirements, and assembly details shown on approved drawings.
Use measuring tapes, steel rules, spirit levels, squares, bevel gauges, calipers, and other measuring instruments as required.
Verify dimensions before cutting, fit-up, welding, and final assembly.
Check material dimensions against drawings and report discrepancies to the supervisor.
Confirm the latest approved drawing revision before starting work.
Seek clarification from the supervisor or engineering team if drawings are incomplete, inconsistent, or unclear.
Avoid unauthorized changes to dimensions, component configurations, or design details.
C. Piping Fabrication and Fit-Up
Fabricate piping spools using pipes, elbows, tees, reducers, flanges, branch fittings, valves, and other specified components.
Verify pipe sizes, wall thicknesses, material grades, and fitting specifications against the approved isometric drawing and material requirements.
Mark cutting locations and prepare pipes to the required dimensions.
Perform pipe end preparation, beveling, edge cleaning, and fit-up preparation as specified.
Position elbows, tees, reducers, flanges, and branch connections in the correct orientation.
Check flange alignment, bolt-hole orientation, face-to-face dimensions, and component rotation against the drawing.
Maintain the specified root gap, internal alignment, hi-low limits, and joint preparation requirements.
Check spool dimensions, overall length, offsets, and orientation before releasing the assembly for welding.
Coordinate with welders to ensure that the fit-up meets the approved Welding Procedure Specification (WPS) and project requirements.
Ensure piping components are adequately supported during fit-up and welding.
Prevent contamination of stainless steel and other materials requiring special handling.
Protect flange faces, machined surfaces, threads, and instrument connections from damage.
Ensure that temporary attachments and tack welds are handled according to approved project procedures.
Report any mismatch, incorrect component, or dimensional discrepancy before welding begins.
D. Structural Steel Fabrication
Fabricate structural steel beams, columns, base plates, gussets, brackets, stiffeners, frames, platforms, ladders, and handrails as assigned.
Read structural fabrication drawings and identify member sizes, material grades, hole locations, and connection details.
Mark, cut, drill, grind, and prepare structural members according to approved drawings.
Assemble structural components using appropriate fixtures, clamps, and measuring tools.
Verify squareness, straightness, level, plumb, diagonals, and overall dimensions.
Prepare components for welding or bolted connections according to the approved design.
Ensure that holes, slots, notches, and cut-outs are positioned correctly.
Maintain required tolerances and prevent excessive distortion during assembly.
Coordinate with welders and inspectors to resolve fit-up and dimensional issues.
