Profile

AWS-certified structural welder with 11 years of experience in heavy industrial and pipeline fabrication across petrochemical and offshore sectors. Specializes in SMAW, GTAW, and FCAW processes on carbon steel, stainless, and chrome-moly alloys up to 2-inch wall thickness. Maintained a 99.2% radiographic pass rate over 3,000+ weld inspections and reduced rework costs by $47,000 in a single fiscal year.

Work Experience

Senior Structural WelderMar 2019 - Present
Gulf Coast Fabricators LLC, Baton Rouge, LA
  • Executed SMAW and GTAW welds on high-pressure API 5L pipeline spools for three refinery turnarounds, achieving a 99.4% first-pass RT acceptance rate across 1,200 weld joints.
  • Mentored a crew of 6 junior welders on fit-up tolerances and weld procedure specifications, cutting average rework time per joint from 4.2 hours to 1.8 hours over 18 months.
  • Collaborated with QC inspectors to revise pre-heat procedures for P91 chrome-moly pipe, eliminating 14 repeat heat-treat failures and saving an estimated $31,000 in material and labor costs.
Pipe Welder IIJun 2015 - Feb 2019
Magnolia Industrial Services, Geismar, LA
  • Performed FCAW and SMAW on structural steel and process piping for a $220M ethylene plant expansion, completing 2,400 linear inches of certified weld deposit ahead of a 6-week compressed schedule.
  • Maintained personal radiographic reject rate below 0.5% across 800 inspected joints, compared to a site average of 1.9%, over a 14-month project duration.
  • Operated post-weld heat treatment equipment on alloy steel assemblies, logging and verifying 300+ thermocouple charts in compliance with ASME B31.3 requirements.
Welder / FabricatorAug 2012 - May 2015
Delta Steel & Fabrication, Zachary, LA
  • Fabricated structural steel frames, handrails, and pressure vessel nozzles using SMAW and GMAW processes, producing an average of 180 weld joints per week with a 97.8% visual inspection pass rate.
  • Reduced material waste by 12% by implementing a nest-cut planning method for plate steel, saving approximately $8,400 annually in raw material costs.
  • Completed AWS D1.1 structural certification test and ASME Section IX groove weld qualification within the first 90 days of employment, enabling assignment to higher-margin certified work.
