- Prep, square, align, and tack components using appropriate tools and techniques.
- Fit nozzles (threaded, SW, BW, flanged) with proper orientation, projection, and weld prep.
- Perform advanced layout including heads, shells, saddles, stiffeners, and internal structures.

Tools & Equipment

- Operate cutting torches, plasma, grinders, drills, overhead cranes, jacks, and alignment tools.
- Use precision measuring tools (levels, squares, micrometers, calipers, pi tapes).
- Safely rig and move heavy components.

Workmanship & Quality

- Maintain high standards of housekeeping, 5S, and organization.
- Check work for squareness, alignment, bevel correctness, and dimensional accuracy.
- Verify fit-ups prior to welding, ensuring proper gaps, land, and root alignment.

Collaboration & Leadership

- Work closely with welders, supervisors, engineering, and QC.




- Mentor junior fitters and apprentices.
- Provide feedback on drawings, BOM discrepancies, and manufacturability issues.
- Support continuous improvement initiatives (Lean, 5S, etc.).

Required Experience & Qualifications

- 7+ years of fitting experience in an ASME Section VIII pressure-vessel fabrication environment.
- Proven ability to fit complete vessels and assemblies independently.
