Welding Processes

TIG Welding (GTAW)

Precision welding for thin materials, stainless, aluminum, and critical applications. Clean welds with no spatter — ideal for visible structural work and high-purity environments.

  • Thin gauge carbon and stainless steel
  • Aluminum, copper, magnesium alloys
  • Aerospace and food-grade applications
  • Critical pipe and tube welds

MIG Welding (GMAW)

Fast, productive welding for medium to heavy carbon steel. The workhorse for structural fabrication, production runs, and most industrial repair work.

  • Carbon steel up to 1/2" thick
  • Structural fabrication
  • Production welding runs
  • Heavy equipment repair

Stick Welding (SMAW)

Field-tough welding for dirty, windy, or outdoor conditions. Ideal for heavy structural work, pipeline repair, and oilfield service where shielded gas isn't practical.

  • Heavy structural carbon steel
  • Pipeline repair (cellulose & low-hydrogen)
  • Outdoor field welding
  • Cast iron and dissimilar metal repair

Flux-Core (FCAW)

High-deposition welding for thick sections and structural work. Used heavily on heavy equipment overhauls, fracturing pumps, and large fabrication projects.

  • Heavy section carbon steel (1/2"+)
  • Self-shielded for windy outdoor work
  • C-Frame overhauls, structural beams
  • Fracturing equipment maintenance

Materials We Weld

Carbon Steel

A36, A572, A500, A992, mild steel plate and structural shapes. Thicknesses from 1/8" to 4"+.

Stainless Steel

304, 316, 321, duplex. Food-grade and corrosion-resistant applications.

Aluminum

5052, 5086, 6061, 6063. Trailers, tanks, transportation equipment.

Alloys

AR400/AR500 wear plate, Hardox, T1, Inconel, exotic alloys on request.

Typical Projects

  • Oilfield welding: fluid end maintenance, frac equipment repair, structural pipe support, well-site fabrication
  • Heavy equipment repair: excavator C-Frames, dozer blade reinforcement, dump truck body repair
  • Concrete plant fabrication: hopper repair, conveyor structural, silo modifications, batch plant retrofits
  • Manufacturing repair: equipment frames, press platens, structural rebuilds
  • Trailer & transport: aluminum trailer repair, frame straightening, custom mounts
  • Custom fabrication: brackets, mounts, frames, hoppers from drawings or sketch
