• Ability to pass X-ray testing on aluminum weldments
• Experience with .052 Fluxcore welding on 3/8" carbon steel plate in 2G, 3G, and 4G positions
• Must meet applicable work location and eligibility requirements for naval shipbuilding projects

Weld Test:

• MIG Pulse weld .047" aluminum plate
• Welding in 2G, 3G, and 4G positions
• Aluminum welds will be subject to X-ray testing
• .052 Fluxcore weld test on 3/8" carbon steel plate
• Carbon steel testing in 2G, 3G, and 4G positionsWe are seeking experienced Structural Welders with advanced skills in welding both carbon steel and aluminum plate for structural fabrication and heavy industrial or marine applications. The successful candidate will be proficient in Flux-Cored Arc Welding (FCAW) on carbon steel and Pulse MIG (GMAW-P) on aluminum, consistently producing high-quality butt welds that meet destructive and non-destructive testing standards.

Candidates must demonstrate the ability to weld in multiple positions and successfully complete rigorous pre-employment welding qualification tests.

Essential Duties and Responsibilities

• Perform structural welding on carbon steel and aluminum plate in accordance with approved Welding Procedure Specifications (WPS).
• Produce high-quality complete joint penetration (CJP) butt welds in multiple welding positions.
• Weld structural components while maintaining dimensional accuracy and proper weld quality.
• Read and interpret blueprints, fabrication drawings, welding symbols, and work instructions.
• Prepare material by measuring, beveling, grinding, fitting, and aligning weld joints.
• Operate FCAW, GMAW-P (Pulse MIG), grinders, plasma cutters, and other fabrication equipment.
• Inspect completed welds for proper penetration, fusion, profile, and workmanship.
• Perform weld repairs when required while maintaining quality standards.
• Work safely while complying with all company, customer, and OSHA safety requirements.
• Maintain clean work areas and properly care for welding equipment.

Required Welding Qualification Tests

Applicants must successfully pass the following pre-employment welding tests:

• Process: Flux-Cored Arc Welding (FCAW)
• Wire: .052" Flux-Core Wire
• Material: 3/8" beveled carbon steel plate
• Joint Configuration: Butt joint with backing strip
• Test Positions: 2G 3G 4G
• Test coupons will be subjected to guided bend testing.
• Welds must meet all applicable visual and bend-test acceptance criteria.

Aluminum GMAW-P (Pulse MIG) Qualification

• Process: Gas Metal Arc Welding – Pulse (GMAW-P)
• Material: Aluminum plate
• Joint Configuration: Butt weld
• Test Positions: 2G 3G 4G
• Test coupons will undergo radiographic (X-ray) examination.
• Welds must meet all applicable radiographic acceptance standards with no unacceptable discontinuities.

Required Qualifications

• Minimum of 3 years of structural welding experience in heavy fabrication, shipbuilding, marine repair, defense, transportation, or industrial manufacturing.
• Demonstrated experience welding structural carbon steel using FCAW.
• Demonstrated experience welding aluminum using Pulse MIG (GMAW-P).
• Ability to produce high-quality butt welds in flat, horizontal, vertical, and overhead positions.
• Ability to read and interpret fabrication drawings, weld symbols, and welding procedure specifications.
