Structural Welder Job Description
The candidate should possess a minimum of five years welding experience in shipyard with flux-core arc welding (FCAW). FCAW is a minimum requirement for ALL welding positions. Work will be performed in shop, production table, and shipboard environments.
Using the approved parameters and filler materials, the welder will weld various joints (fillet, groove, and lap) in all positions and with multiple passes. The completed welds must meet quality standards and work must be performed in accordance with safety policies and procedures.
The welder will also perform cutting and gouging with carbon electrodes to cut, shape, and groove metal. The welder will also use various pneumatic and electric tools to grind excess materials, remove discrepancies, and clean weld joints.
Assessment Criteria
If a candidate was previously certified at NASSCO, but the certifications are currently expired, the candidate will need to recertify by accomplishing a 3G (3/8” groove weld joint with steel backing). Candidates who are new or do not have certification records in the company’s system will need to complete the assessment requirements described below.
Note: During the assessment and requalification, the candidate must follow all safety procedures. Any safety infractions will result in disqualification.
FCAW Welding Process
The candidate must demonstrate the consistent ability to perform flux core arc welding with carbon dioxide (CO2) shielding gas.
During the assessment process, the candidate must demonstrate the following:
- Perform assessment safely (adhere to all safety requirements)
- Conduct shielding gas drop test
- Change wire
- Measure fillet welds
- Set weld parameters and achieve proper surface preparation prior welding.
Perform welds that pass all required tests (visual inspection, fracture test, and ultrasound test).

Assessment Location
Weld School
Structural Welder FCAW Assessment
The welding assessment will be conducted at the shipyard, in the Weld School. The duration of the assessment varies based on the skill and ability of the candidate. The timeframe is between 1.5 to 3 days. The candidate will be provided a maximum of one (1) hour for familiarization with the equipment.
Module 1 (4-8 Hours)
Process and Positions
Testing Requirements
Vertical, horizontal, and overhead on a 12 inch fillet joint.
Horizontal, vertical, and overhead 3/8” plate with backing strip using 811N3 0.045” wire.
- S9074-AQ-GIB-010/248 REV.1
- Visual Inspection (Mil-Std-2035)
- Ultrasound test (UT) inspection.
Module 2 (4-8 Hours)
Process and Positions
Testing Requirements
Three (3) plates with ceramic backing tape. Positions include vertical, horizontal, and flat on a ¾” X 12” plate using filler material 81K2-C 0.045 wire.
- Requirements for welding and Brazing procedure and Performance Qualification (S9074-AQ-GIB-010/248 REV.1)
- Visual Inspection (Mil-Std-2035)
- Ultrasound test (UT) inspection.
Module 3 (4-8 Hours)
Production Simulation
Production simulation consists of the following tests using 81K2-C with 0.045 wire:
- 36” fillet joints with wraps (flat and vertical).
- 36” fillet joints (flat, vertical, diagonal, and overhead).
- Watertight collar (inner and outer weld joints).
- Air arc equipment set-up and single pass weld removal.
- Koike/Bug-o welding carriage equipment set-up and single pass weld.
Aluminum Welding Assessment
Welders who are certified to weld aluminum and categorized as structural welders. Upon completion of the aforementioned certification (FCAW), the candiate could conduct an assessment on aluminum welding if he/she has adequate experience with this process.
The aluminum welding is based on marine-grade 5xxx, which is required on certain military vessels – particularly on Repair projects. The assessment duration is 2-4 days (not including FCAW assessments).
The following provides assessment requirements for 5xxx aluminum welding:
Module 1 (1-2 Days)
Process and Positions
Plates: 12” in length, ½” thick (aluminum backing and ceramic backing).
Positions: Flat, vertical, horizontal, and overhead (overhead with aluminum backing).
Gas: Mix gas Helium (He) / Argon (Ar).
X-ray test
Module 2 (1-2 Days)
Process and Positions
Testing Requirements
Simulation: 5xxx
Positions: Horizontal flat, vertical, overhead fillet welds on 6” T-bars
Insert: 6” insert on ½” thick material with ceramic backing.
Visual test (VT) inspection
Pipe Welder Requirements
The ideal Pipe Welder candidate should have a minimum of five years welding experience. This candidate should have experience with structual welding as well as pipe welding, as this position will require the ability to perform work on both processes.
During pipe welding assignments, the candidate will utilize FCAW and GTAW processes to weld groove joints as well as fillet joints. In most cases, these weld joints will be in restricted positions, thus requiring advanced-level welding skills.
Prior to conducting pipe welding assessments, the candidate must first accomplish the structural welding assessment. The pipe welder assessment entails four modules, as referenced below.
Pipe Welder Assessment

Assessment Results
The Training Admin will email the assessments to the Subcontractor Admin Team. Candidates who pass the assessment will move on to Pre-Boarding.
Note: Aluminum plates require x-ray testing by a third-party entity. This could require additional time to process the plates.
Prerequisite Training
Candidates must complete all prerequisite training prior to their first day of work. It is the Coordinator’s responsibility to provide the Sub Admin valid evidence of a Candidate’s completion of prerequisite training.
