OUR SERVICES:

Structural Repair and Restoration

This involves restoring the integrity and strength of load-bearing metal structures. Our expertise covers:

  • Crack Repair: Identifying and repairing stress fractures, fatigue cracks, and impact damage in steel beams, columns, and trusses using specialized welding procedures.

  • Corrosion and Wear Repair: Removing corroded or worn sections of structural steel and welding in new, custom-fabricated replacement plates or components to restore original strength.

  • Reinforcement and Reinforcing: Adding steel plates, angles, or other structural shapes to existing structures to increase load capacity or meet updated engineering specifications.

  • Connection Repair: Re-welding or repairing failed bolted or welded connections in steel frames, bridges, and industrial platforms.

  • Damage Restoration: Repairing structures damaged by fire, impact, or natural disasters, including heat straightening and component replacement.

Energy Infrastructure Solutions

We provide highly specialized welding and repair for the entire energy sector, from generation to storage.

Battery Energy Storage Systems (BESS) Repair:

  • Enclosure and Housing Repair: Welding and patching cracks, punctures, or corrosion on BESS container shells and support frames.

  • Rack and Tray Restoration: Repairing the structural racks and trays that hold battery modules, ensuring their stability and safety.

    EV Battery Repair:

  • Casing and Housing Welds: Precision TIG welding to repair damaged aluminum or steel battery casings.

    General Power Infrastructure:

  • Pipeline and Penstock Welding: High-pressure pipe welding for power plants, oil and gas facilities, and substations.

  • Turbine and Generator Component Repair: Specialized welding repairs on non-critical components of power generation equipment.

  • Support Structure Fabrication: Welding custom support structures, platforms, and mounts for energy equipment.

Complex Containment and Pressure Vessel Repair

Our services ensure the safety and reliability of systems designed to hold liquids or gases under pressure.

Tank and Vessel Repair:

  • Leak Sealing: Identifying and welding leaks in storage tanks, pressure vessels, and industrial containers.

  • Shell and Seam Repair: Repairing cracks, pitting, and corrosion on tank walls and weld seams.

  • Nozzle and Flange Replacement: Cutting out and replacing damaged nozzles, manways, and flanges.

  • High-Pressure Pipe Welding: Performing certified code-compliant welding on pipelines used for steam, chemicals, or other critical fluids.

  • Liner Repair and Replacement: Welding repairs for metal liners inside tanks and other containment structures.

Critical System Recovery & National On-Site Emergency Response

We excel in high-stakes environments where rapid response and precision are essential for minimizing downtime.

  • National Emergency On-Site Welding: Rapid deployment of mobile master welder to perform urgent repairs on failed machinery, equipment, or structural components.

  • Temporary Bracing and Shoring: Fabricating and welding temporary supports to stabilize damaged structures until permanent repairs can be made.

  • Heavy Equipment Repair: On-site welding repairs for cracks and damage on heavy machinery like cranes, excavators, and industrial plant equipment.

  • Rapid Prototyping: Quickly fabricating unique, one-off parts or patches to get a critical system back online.
